Airthings

it used to work great. now i cant get the thing to sync. tells me sync to refresh the data, but wont. i refresh it and everything, and it does not even try.

neat data

Good product but does not stay connected to the internet as implied unless you have a wired network connection. The device connects to the internet wirelessly if you open the app and then force an internet connection to your router. This is probably done to extend battery life. Battery does not seem to last as long as advertised. Usually need changing every 4 to 6 months.

The dates in 7-day and 30-day views are misaligned. Please fix.

not working

highly recommend 👌

Very nice and good UI/UX in the app

works great, graphing of data is automatic which is great.

it is disappointing to see that such an expensive unit (brand new View Plus with good batteries and constantly powered through USB-C) does not hold the measures when the Internet is down so they can be transmitted later. Yes, while online, it does an amazing job.

Why do I need a stupid app to just use an air monitor???

Works the way it is supposed to.

The airthings is good to have. Without one you are blind to your air quality.

I never get a notification that the battery is dying and sometimes have issues with syncing but generally a good app.

Great app and air monitoring device. I use it to monitor the radon, temperature, and humidity levels in my basement. It's very accurate and reports continually in the app on my phone.

Battery dies quickly

Didn't want to review, kept begging for it, so this is what you get for begging non-stop without allowing me to select an option that says don't ask me again.

I'm giving an honest review here. I bought an Air thing corentium 2 last winter. after 3-4 months it stopped working saying I had to contact support. which I did, and the support guy (Don) was awesome through the whole process of troubleshooting and sending a replacement. now the replacement worked fine for 5 months full (mid May to mid October 2026) and now it says "CONTACT SUPPORT" Again. at this price point I expected at least a reliability of 3 years. I don't want to contact support anymore

This app does not support sharing access to the device with another user. This is a pretty basic feature for most smart monitoring/security apps. I created a new account for another user, added the device, but it reset the device and all the data! I also no longer have access to the device from the original account. There was no warning that would happen. So now I have lost all my air quality data which was the sole purpose for buying the view plus.

Total Disappointment. Their most expensive device stopped working right after their limited warranty period. And they are refusing to replace it. After investing heavily on this ecosystem, this approach is unacceptable. These are not cheap Chinese thermometers but advanced and expensive devices. I don't suggest anyone to spend their money on this brand.

it's average but accurate

Solid app. Never had an issue, not stuffed with advertisements or marketing notifications. does exactly what I'd expect in a well designed and easy to use UI.

can't trust the app graph values and I can't get an answers from the customer support.

very good at monitoring the air quality in my home.

working well

Poorly designed. This app is designed to communicate via Bluetooth to the airthings radon monitor. Why it needs to be connected to the internet to do this I do not know. We had a power outage and I wanted to check radon levels and I could not because there was no internet connection at the time. If all you are doing is reading data off of the device why do we need to be connected to the internet? in order to get a reading I constantly have to play with it.

dont understand why everything need the internet, cant use offline

I bought the mini wave. However it doesn't do all of the things advertised on the front of the package. It also seems like if you look at their other products, they only do 1 specific things so in order to get a complete picture of the quality and safety of the air you're breathing you have to have more than 1, and they are somewhat expensive. I went a different route.

UI needs work

connectivity for wave mini is weak customer service is poor

Working Well!

Wonderful snap shot of my sealed crawl space, very accurate, will always have one in olace!

They removed the important battery status from app start page, so you have to go down into setting to see battery level. please put little battery back on home screen!

easy to setup gives you consistent reading after 24hr to a week its now been 2 weeks and its gone from 270 to 350 im having someone come in friday to put in a randon set up in my sump room, so glad i bought this, ill update after its installed and see where the readings sit.

Works most of the time, low battery is not managed well and can cause data loss.

Best device I've seen on market, a keeper

historical data has been removed from app

For such expensive devices, the data is represented pretty poorly in this app. It provides graphs of air quality over different periods of time, but the most important information, the air quality right now, doesn't match across these graphs and it's hard to tell how recent the results are. I don't know if it's a deficiency of the devices or the app, but so much of the focus seems to be on average air quality over time whereas I care way more about air quality right now.

just never get the Bluetooth sensors

great and accurate device

seems to be working great! information being received that I had no idea how what condition my finished basement was in.

needs manually refreshed since they replaced the old app. looking for a replacement that os active monitoring again

A must have device if you live in an area with high radon.

Works like it says following radon levels

The app won't Bluetooth sync in the background, and it throws ads up periodically.

people were acting like I was exaggerating about smelling cigarettes in my smoke free building until I showed my building manager the exact timeline of when it's happening overnight. the convenient graphs are undisputable proof!

too difficult, not random grafic

Excellent tool for the homeowner. Very accurate.

it's exceptionally annoying that i have to open the app and manually update the status. you cant schedule refreshes, so your ability to see metrics over time depends on remembering to manually updating it on a regular basis.

Great product. I recommend it to my customers that are concerned with their indoor air quality.

works good.

Radon sensor is fantastic

it sucks. because it's at a low poi

working as expected. I appreciate the updates and insights

Discrepencies between two devices. I have been using two diferent devices, placed one next to the other for the last 5.5 months: Wave (since Jan 2025) and CorentiumHome2 (since Feb2026). The radon readings between the two have major separation in absolute values with Corentium showing up to (and sometimes even more than) twice the values read by Wave. The trend seems to be the same between the two though,as far as I can see with the naked eye. Do they need a recalibration of any sort?

Works well, great info at my fingertips.

The old software worked just fine. This updated does not work at all. Always asking me to sync and will not sync.

the original app was easy to use and I could quickly see what I needed to know. now I don't even know where to find the radon level or anything else. Why change a good thing?

Excellent monitoring, a must have in every home with a basement. If you spend time in your basement you need this to monitor radon levels. Very easy to use, place in basement and walk away. You'll get reports right away, but long term monitoring will give you a better picture of the radon levels.

I don't get it. I know I need to wait for some of the data to stabilize, and it's only been a week, but for the data I could reasonably see today, the combination of unknown measurements (bqm3, ugm3, ppb, inhg - literally Greek in some cases) and the defyingly dumb interface means I can't figure out even where to find the graph I saw yesterday of barometric pressure. There's a learning curve here and I'd like an eli5. I'll come back and review again once I'm less frustrated

awesome detector

It is glitchy. Doesn't sync when needed.

Great app when it works. never connects to my device. is there anyone i can email about this

NO AUTO SYNC, which means you need to open the app and sync the data yourself when you're near the device, otherwise you don't know what the readings of Radon are. Sorry, but this make the app completely useless. It used to be a better software, and btw a way better support (last time I contacted them, the guy was responding usually after my second message, and it took him a couple of days!) Today I would consider buying a device from another brand

Unusable. The app can see my sensor but refuses to add it to my home.

Wonderful device

I find the interaction with cell phones is incomplete. For instance, if you change your phone, the data disappears until you reconnect your new cell to the Airthing... I lost data twice because of that. Another thing, if you read data for a short period, you see the spikes, but if for a long period, you don't see the spikes anymore, i find the spikes super important. one more, if you download the csf file, you need more software to make a graphic out of it, grrrrr

Not a fan that I can't use the device without the app or an account.

Packed full of usefully information, great app. .......Love it!

would be nice if it was wifi not just BT.

app doesn't sync with device or save data properly

the app is waaaaay to slow to load the data

when device fails the company stops communicating. 15 months for 250 bucks. buy a different product

Excellent app! Works exactly as it supposed to! Finally I have a full overview of my indoor air quality including Radon (which is a problem here in Switzerland). Thanks to this app, I know now that my Radon values are good, but must ventilate often! I have 2 suggestions: 1- it would be great to have an outdoor unit to compare with, 2- Please add a switch to the app to change between air pressure at the device altitude, and air pressure at sea level (which is the commonly used value!) Thanks!

well I don't understand why the old app didn't update the very first time of trying to log into this app it said I'd tried to log in too many times and I had to try back later. it was the first try. I'd give zero Stars if I could

Zero trust in this company. There should be a provision to scrub data and restart as well. App and poor s/w execution always reveals the underlying failure of companies like this. Expensive toy at best...

handy

June 2026 edit: Looks like ANOTHER bad apo update. Now the graphs will not load unless I open the app, kill the app, then open it again. SO SICK of these extra steps!! FIX YOUR APP!! From 2024 review: AirThings recently put out a buggy Android app release and got a lot of bad reviews for it (including one from me). But their customer support and subsequent app update were impressive. Revising my rating.

it would be great if graphs could just stay at a static range. scrolling through something like air pressure is annoying when the size of the chart keeps changing as I scroll. I'm trying to get an idea visually of the changes but that makes it so much harder. The pollen forecast is laughable, just giving some vague levels without any meaning behind them. it also shows "today" twice(or today is Tuesday, so it shows Today and Tuesday) but with different forecast values.

Have HAD Airthings Radon Detector (ARD) for 16 months with satisfactory performance. I LIKED having the graphs, which I could correlate with factors such as rainfall. Would say it WAS a 5* device/app combination. HOWEVER, upon installing app Ver 8.0.5 a few weeks ago, I lost ALL 16 months of history. It also does not seen to be collecting new history. I get only CURRENT readings. Most of the ARD's value to me has been lost. It is now a 1* device. Nice update!

sensor won't load all the info. says it needs firmware update. try to do update and nothing happens.

Constant sync issues since the migration to the new app. Makes me consider throwing out the device at this point.

I've got to figure out what to do with the data.

Would be better if it worked with Google Home.

old app was much better as this new one is constantly looping "fetching data" instead showing any actual data. Solution was: log in browser and it automatically started working on phone.

wave + from 2021. The first 4 years no problem only slow sync. then after pushing new app i was disappointed as is less user friendly and syncing is slower, you cannot lit the unit on app and can't see the battery status. after 5 years now the new firmware update was pushed and im not able so sync anymore and the support is slow and inefficient. i just wrote i can send to them and let them play with it. I tried all possible.

Device never finishes syncing, blocking ability to see plots.

Good app

I haven't had any problems, very reliable. We have large and ancient dogs, a 17 year old at 51 pounds and 12, 83 require additional needs and monitoring their humidity, temperature, and overall air quality is crucial. my 83 pound dog is very sensitive to humidity and the push notifications have come in very handy with adjusting their environmental needs.

når jeg prøver å hvilke som helst grafer så står det bare "fetching data" og jeg ser aldri noe annet enn live verdier i appen

bugs fixed, thank you!

works but App sucks

Becoming very intrusive with notifications and all kind of proposals. They believe they are the only application in the phone... didn't find a way to sync my device. Missing the good old app. Example of 'doing too much' edit; +1*, the sync is launched by "pulling down" the sensor name field. This was not obvious, a simple button is much better... Edit: Stay away from this useless app. Most of the time, the sync simply hangs, then no way to see the datas. Now using Home Assistant.

everything is good

overall the app usually works and connects. I wish we were able to change the order in which they update.

suddenly getting advertisement notifications.

The product is not really accurate and sometimes they show a factor 10X to 15X of normal value. I am disappointed compared to the price tag.

For 6 months already, the new app no longer syncs in the background. As a result, I don't get any timely notification when the air quality is bad. I have to manually open the app and do a sync before I get any alert, which makes it rather useless. The old app, by comparison, while much more basic, reliably syncs in the background and gives me timely alerts, which makes it infinitely more useful than this new app.

Not even one star. Same goes for their Wave Plus thing. Costly gadget that provide absolute zero value and/or use. Sync fails. Fw update fails. Unpairing fails. Everything fails. Airthings fails.

very easy to set up and use

The new app removed the auto background sync for Bluetooth. On the old app, if my phone was in range it would auto sync and give me notifications about my air quality (ie. if radon is too high). The new app does not do that and will only update/sync if you open the app and manually sync the device. This defeats the entire purpose of having a connected air quality monitor if you have to manually check it everytime.

Devices are OK. Every once in a while they stop collecting data. There's no option to reboot in the app. Which is a FAIL for any device app. I have to manually reset. Should AirThings repy, don't bother, update your app so it detects failures and reboots itself. Your devices are too expensive to not have such features. And I use a USB cable for continuous power, just more fail...

fantastic idea but lousy execution. x axis labels are unreadable. Too small and too faint. and having that axis move around dynamically compounds the legibility problem because the axis moves up and down. this should be easy to fix if anyone is paying attention

The updated version has somehow extended the battery life of my Wave Mini, which makes up for the fact that it no longer displays battery status as precisely as the old version.

Working great until May12, then all 4 of my Views "spontaneously" lost network connectivity. Support has so far only provided a standard troubleshooting document, so no real help. Hoping they do more. As others have mentioned, network connection should be a lot easier.

The application used to work very well, but since the last update I can manage to access my device's historical data and when syncing it gets stuck in syncing status endlessly. in addition Support never answer emails.

I originally purchased the View Plus and wave. The reassurance the data provides is excellent ensuring I take mitigating steps should I need to such as opening window to increase ventilation. I have now also purchased the Renew. The Renew really helps to keep my air clean, mostly left on auto but when I need to I change to boost. Excellently made, premium looking and conversation starter. I'm very happy.

The app has stabilized since the last update. It's now reliably syncing with my two Airthings units as soon as the app is opened. I just wish it had a 'run in background' option. We had a week of extremely low temperatures in February and my radon mitigation system stopped working due to ice in the exhaust pipe! The Airthings unit in my basement detected the problem and the app alerted me. Very helpful.

new app won't sync with the devices. I can never tell if it's logged on or not. older program was easier to use and check but now it is just a waste of my time.

The UI is barely an improvement from the old Airthings app but what's immediately frustrating is that the new one has not been able to consistently sync. I've switched back to the old app as it always syncs. Update: problems with the new app not syncing have been resolved. The UI/UX has also been overhauled and is much better now. I still think I prefer the old app's line graph though.

The last update ruined the app. Ever since I updated this app yesterday I cannot sync my 2 wave devices. It starts to sync the 1st one then freezes. I now have no idea if the readings are accurate.

This airthings is a great device but the company has set it up to hammer your wifi network. As such it will connect/disconnect hundreds of times each day and overwhelm your wifi log/overuse network resources.. there is no reason for this, but support says thats how it works. Because of the way all new routers hate this type of connection, I've stopped using the device. There is zero reasons the company cannot change the wifi to just stay connected, but they won't update it properly.

Great devices and app. I have the view and the wave. I put the wave in my crawlspace and the view in my basement for monitoring radon. Both devices have proved invaluable at monitoring and also helping to locate radon infiltration points. I wish I could see the info from both devices on the same trend. Mainly radon. When radon levels fluctuate, it would be nice to be able to see which monitor goes up first. It's not hard to look at the individual trends but it's easier if they were on the same.

Seems like it works great! I would only suggest to make a note that a mitigation was completed and to start a new statistics period from that point of time. I think it would help monitoring.

This company ruined connectivity between my measurement device and phone by bluetooth on purpose so they could sell connection hubs to customers with already working single device. They made accessing the data by BT almost impossible by firmware and app changes that were forced. You can't sync with the device anymore by pressing a button in app, it's totally arbitrary now if it happens or not, and without hanging about the device with the app open for tens of minutes you never get to see data.

All old data is gone! Why wouldn't they just update the app instead of completely wiping out the old one? And if you're going to create a new one, *import our data into the new app* , it's in the same account! Radon fluctuates over time, so basically this is little starting from a brand new device. So disappointing.

The device synced once and then stopped syncing entirely. I followed the troubleshooting steps, kept my phone right beside the unit, and still got no usable data. For a brand-new product, that is not acceptable. Support was courteous, but the product was unreliable and the return process felt more cumbersome than it should have been.

I initially bought one to check radon levels in our basement. As the results started to accumulate over a month. It turns out the basement was at a red level and we need to install a radon exhaust system ASAP. After a few more months of checking for Radon, Humidity, and Temp levels. I decided to also purchase the mini. The mini checks bad air and gas. I have the combo going at all times. The devices only take a few AA batteries and last for months. The app is super easy to use. I love it.

The new app no longer supports automatic syncing, which is a major issue. Users expect to see their data immediately upon opening the app, but now every time you launch it, you must manually trigger a sync and then wait 15–30 minutes before new data appears. This change effectively makes Wave device unusable for most people. The previous version synced automatically without any issues. Update: with new app, one has to wait 29 days before you can see radon data after replacing battery.

Its nice to have a reasonably priced real-time radon monitor, but I have two major gripes with this app: (1) even though I'm getting a constant radon reading on the device itself throughout the day, when I go to look at data in the app it says "no data" regardless of what time period I select. (2) there is only a single push notification setting for the app; there's no way to disable the weekly nag message that doesn't give you any useful information

dropping a star.app was better, when they cut over to the new app, they deleted all my data or didn't migrate it, so that's unfortunate as I've been using them for years. the new app is slower than the previous, the graphs are more crayon like in drawing and don't look as precise, they always need to pause to update and seems to favor Bluetooth now even though I have a hub, I'm missing one of my devices that's still visible in the old app, and devices drop off now with no warning of low battery.

The app unnecessarily requires Internet access to work, a big problem for me. There is no app option for data download to your phone, you must use their website for that. Data sampling issues seem to have improved, but the app has stopped automatically collecting data. I have to start the app and manually trigger download of data from the sensor.

Since the forced update the app doesn't poll the sensors in the background anymore, which makes all the notifications just silly. If I'm in the room I know it's cold. Bought four, one worked; rest had corroded AAs in the package. One of those worked after being brushed hard, but it's failed again. Customer support wanted the date codes off cells tossed months earlier and ultimately offered nothing.

I don't like the new interface. the old app allowed you to see radon, temperature and humidity as a stacked view and see the correlation between them at any given point in time. please bring back this view. Additionally, now you cannot choose a custom date range to extract averages. Please bring back this functionality.

The Older App was Better. This new app doesn't automatically sync. You must do manual syncing which makes using the Wave Mini useless for me. I was getting VOC and temp alerts before and now I have to sync. No more alerts. The app is nice looking though. If I knew I was not going to be able to get alerts I would not have spent so much on the devices.

Why is syncing so damn hard. Come on people this is a primary feature that should be bullet proof. You need to set up rigorous testing after even the most minor software changes to make sure everything is perfect. Your customers use many Bluetooth devices and know what a normal pairing experience is supposed to be. when I read all of the customer debugging you expect when a device will not connect, I do not think you are being reasonable. do not make this our problem.

the old app was just fine, and I miss it. ever since the upgrade, i can not activate the glow light anymore to distinguish devices. they have a glow light button, but its not working, reaching out didn't help, the just referred me to the same instructions. Also, can not reorder devices in device list. can not export data. the app does allow free access to devices, otherwise they would be useless pucks. this review is for the app, not the devices themselves.

Poor design, Data is not accurate enough !! Before the updated version i was able to see CURRENT Radon readings, like what the temperature NOW in real time. Not Anymore. Now l had high reading for 3/4 of a day. Going down very slowly. With old app, i would open up windows and the levels would go down to 0.3 or lower after just 3 hours now it is averaging out everything- stupid design in my opinion. I can see average or readings over several days, why did you take this away???

Way too many app changes over the time I've owned it, and their app is way too invasive. Don't like it. The sensors are fine, but since you can't use them without the app, I'm judging it on the worst part of their whole system. Terrible. Very slow to update, and I regularly have to do multiple update cycles to get it to pull the data from all of our sensors.

Using BT I can see recent values, but the graph doesn't plot them. This is because the graph only updates when the latest batch of recorded values are sent over (usually every hour); to limit the BLE traffic and in effect save battery. But it would be nice to still plot the recent values so that I can compare them with the others!! Then on the batch update it could just fill in any missing ones! Please fix! Also graph doesn't show max values, they're hidden because of averaging! That's very bad!

displays the data in easy to read ways. Now, 1. if only I could select the thresholds where the app notifies me, 2. i could display a single type of air contaminant in my home (ex show all the radon for all sensors, scroll down a little and show all CO2 levels throughout the home, and so on) it would be perfect.

The current app Ux is horrible. The data sync status is not easy to see; the information kind of exists on the dashboard but does not match what is visible in the graphs. Navigation inside and between graphs feels like giving worm medicine to your cat: painful, frustrating, you don't really know if you got it all in, and in any case the result is an ugly mess. It is quite sad that the monitoring devices seem to do ok job for the price point, but the app makes it all moot.

No ability to change sync rates. The View Plus device connects and disconnects at least 1700 times a day. It caused my router to reboot from CPU errors at least once every two days. it would be nice to change the update frequency so that CPU cycles on the router are not wasted on updates I do not care to have so frequently.

Was forced to upgrade to the new app after the (perfectly functional) old app was deprecated. The new app does *not* allow background syncing with bluetooth like the old one did, instead the AI chatbot is prompting me to buy a hub. At least give the option to allow for background syncing. No, I don't want to buy a hub to support my *one* monitor. edit: turns out the AI assistant was prompting me to buy an airthings hub to fix this problem, but that product doesn't exist anymore. thanks guys

I'm off-grid with no wifi and rely only on mobile data. If my signal is bad, despite Bluetooth, I cannot access and get readings from any devices. I just get a network error saying try again later. I should be able to access the devices using Bluetooth regardless of whether I have an internet connection. Also, the app update is miserable. It's impossible to see all chart data for temperature, for instance, in a single screen for one day, just small segments of the chart with paging.

A little expensive, but you get what you pay for. Nice online interface with different time scale ranges. I'm using a Wave, and View Plus together, and the connection is flawless, and constant. View plus needs to be powered with USB to connect by wifi. I've had 3 different radon detectors, and this one is slightly less sensitive, but reasonably accurate for what I need. I would love to have outputs to control a humidifier, dehumidifier and air purifier. Very satisfied with this product.

The new app makes it unclear on how to sync the device. they really need a simple button instead of a pull down of the screen which is sometimes faulty on some phones. Additionally, the old app would align the line graphs one above the other so that you could visually correlate humidity and radon levels. that is no longer the case, they are on different screens, I think that was a mistake.

The updated app caused me to lose over year's worth of data! now, the app doesn't seem to connect and just tells me that it takes over a month to gather the data and that I need to wait. There is no way to ensure the device is even syncing with the app. Which leaves me wondering about its validity. Time to trash the multiple Airthings devices that I have and move to a better option / product. Stay away from Airthings!

Doesn't sync in the background any more. Their support confirmed that the new app just doesn't support it. So you won't get things like radon alerts until you open the app. And yes I did the connectivity reset (why doesn't it offer to do this automatically?). It didn't work at all until I did that. Before that, I tried removing and readding my device to fix it. Don't! It says you don't lose your data, but it puts it all in a "past measurement" that can only be accessed in the web dashboard.

Being forced to " log-in" everytime is a real pain in the Ars. The information format was much better on the old app. Original app gave you scaling to make sense of the information. Only positive thing is that it updates or " syncs" faster on the "new" app. If I had a choice I would pick the original app. One word describes this app, "Disappointing".

A downgrade from the old app but it works well enough. I prefer a here and now reading to having to work it out from a graph of 3 hours to one year. Also, not sure if you can actually say always show the three hour average not the 24 hr average. Interface more cluttered than the old one with more clicks required to get approximately the same info. Hope it was a nice school project for someone. Appreciate that an average over hours or weeks is going to be more accurate but it makes it fiddly

This app worked great until about a month or two ago, and it just stopped connecting to the internet so you can't see your device. It just doesn't update, even when you reset it. Apparently they know about the problem but just haven't fixed it. I'm not sure how a company just doesn't fix the connectivity for an internet based app, but it basically renders the device useless for anything accept viewing radon levels on the device.

newer app is disappointing. no battery level indicator and the stats are clunky and congested. prior version of app showed battery signal right on front and then when you look at device it clearly shows readings for each parameter. no fluff no confusion. received an email that old app will be discontinued but I will continue to use it as long as I can even if no longer supported.

Won't graph data... it will sync and tell me the latest readings, but when I try to view the data graph over the last 24hr or 7 days (or any timespan)... it just says "no data". it worked fine for 2 days, then stopped working. very buggy, and disappointing. I might have to return the sensor and buy a product that works better (yes I've tried restarting phone, it successfully syncs, etc).

I like my Airthings Wave. I still learning what affects the radon readings, CO2, VOC etc. I have to reduce my overall rating by 1 Star because of this new app. The main page seems very busy and the labels are smaller. I like being able to "drill down" in the history graphs but in my opinion I would have le left them off the main page. Just my opinion. They are good monitors.

app does not help set up new device, it only tries to collect and sell your personal data. it closes immediately if you do not agree. device itself does not support Bluetooth pairing with app on phone (not visible to phone Bluetooth even tho device reads Add Device and is right next to phone). it would be hard to imagine a less helpful app.

The device appears to work fine. The app is quite frustrating. it offers no search function. It notifies me I have messages to read but offers no way to access them. Then, the message notification goes away. The app offers tips that have a 'Learn More' button that either gets ne nowhere, to a message there is a o problem and I have no access, or in the one link that worked it offered a poor follow up.

I love the updated devices list, which has mini graphs for each device right there in the list. the format is no longer just a list of the devices and their current readings, but more like mini info panels, all laid out next to one another for a quick gathering of not just current numbers, but the trends. Overall, Airthings have been wonderful. not just the devices and their software, but the company and its top notch customer support. I can't recommend them enough!

The new app is disappointing. Sure it syncs with the device, but it does not save the data at all times. Customer Service did not provide much assistance. let's hope there's an update to rectify the problem. Update: After 3 weeks, Customer Service did follow up to check on my status. I'm not sure what they did, but for the last couple of weeks, data is now saved and shown in the charts. I appreciate their help and communication, even offering to send a new unit.

EDIT July 31, 2025. I've boosted my rating to 5 stars. They now allow downloading data by date. This is a massive improvement and keeps files a manageable size. I have a few minor issues with format but I cope easily. It has been perfectly reliable over more than two years. Graphics on mobile are very good and allow you to see a year's data or drill down to 3 hours. Highly recommended.

The new app (that we were forced to change to) really sucks!!!! main problem is viewing the graphs one at a time instead of being able to scroll through vertically. Radon levels in my area changes drastically with air pressure changes, and seeing that simultaneously on the graphs was a value that has been lost with the new app. NOT AN UPGRADE!!!!

I have to backtrack on a recent 5 star review of the new app. I like the layout, BUT I get a ton of connection issues...every 4 out of 10 times. Old app is still installed on my phone and has ZERO issues finding the device for a reading. updates also prevents multiple readings (one after the other) within a short period. You're forced to wait a few minutes before you can get a new reading....that is...if you get past the connection issues. The classic "if it ain't broke, don't fix it."

The app constantly errors out stating "sync failed". This happens despite the fact that both Bluetooth and WiFi are working fine and the Wave Radon sensor is located within 2 feet of the android tablet running the Airthings app. Sync failure occurs more than 50% of the time, and requires re-starting the Airthings app.

UPDATE: The app is working well. Maybe it would be better to show graphs as candles - otherwise peaks are smoothed when zoomed out. OLD: The app was working fine for me before today - like 5 stars fine. But today a blocking screen appeared with a choice either to give green light to "personalize your journey" or "continue privately". Ridiculously, the private option does not work, so I am cut off the air quality data. So 1 star until fixed.

March 2025 still same issues. The previous app was useful & accurate and I was very happy with both its interface and its reliability. This new app is confusing, and clunky and most of the time does not even see my devices. It won't sync, it's not reliable, and considering this is for well over $2,000 worth of equipment, I'm extremely disappointed as the use of the app was one of the main reasons for my purchase. At this point I would no longer recommend their equipment or software.

I've had a Wave for a while before I realized it had a Bluetooth feature. I set it up this morning and connected the app. As soon as it connected it automatically began updating the device firmware without a confirmation prompt or informing me that it would be destroying over a year's worth of Radon data without backing it up first. I feel like that would have been really good to have and now it's starting all over again.

Unable to add device. Trying to push add button and nothing happened. Simply it doesn't work at all. Updated: Customer service contacted me right away to help fix issues with the app. I decided to try one more time myself. I deleted and re-opened my account, then uninstall and re-installed the app. After that I was able to add my device and so far it works OK now

The sync fails. After being forced to update to this app my devices haven't successfully synced. The app is useless. Going back to the wave app while it still exists! I have followed every article on their website and the syncing still doesn't work. I have even completely reset my devices and they sync once and never again after that. Pretty piss poor products for the amount of money they cost!

Why is this considered an upgrade from the first version? It's worse in every way. Connectivity is unreliable, and the app just seems buggy. I used to see all sensors graphed together, but now you have to select them individually. And that's if you don't get a "Something went wrong" message. Why companies continue to "fix" something that isn't broken is beyond me.

Absolutely useless. Just doesn't work. Sick of seeing the message "something went wrong" Do not buy an Airthings device if you are relying on this app to get any information from the device. I gaurantee that you will be disappointed. Why Airthings can't make a device that you can just pair like any other Bluetooth device is beyond me. I can buy a cheap pair of chinese bluetooth ear buds which work better than this. Would give it no stars except there isn't an option for this.

It doesn't alert me when the CO2 levels are high, I have to go into the application to get it to tell me that something is wrong. it's a great sensor with an application that's lacking. I have talked to customer service a couple of times, Bluetooth syncs just fine, when I trigger a sync, but there is no passive monitoring. I was told I shouldn't open a window, around it, how else am I supposed to get fresh air into the room. A series of help desk interactions later and I'm frustrated.

I checked the accuracy of the unit's radon detection with a mail in test kit. I had them in the same location for 4 months. They were within 10% of each other. Good enough for home use. The app is simple to use and as I got the view plus, I am also able to monitor other air quality items. I had some problems with the first unit in that it stopped reading Radon after 5 months. I contacted the company and after a few email exchanges, they replaced the unit under warranty. Highly recommended.

Rarely syncs. App says it is the current version. App says device firmware is current version. After multiple attempts to sync, it says it is up to date, but says it's offline and gives no data in the web dashboard, but appears to display current conditions. Hasn't updated in about 5 months. I was pretty excited when I first got it, but nothing but trouble and I'm very disappointed and I feel like I wasted my money. Looking for a replacement.

Syncing never works so can't do its sole purpose while the old app would sync fine. Just says syncing failed with no actual information to debug with. Edit: syncs fine after resetting it. Though the data from time it stopped syncing to now is seemingly lost so not great. Why it randomly started needing that only on the new app is not clear. Bumped up review to 3 stars. It's ok, but no value improvements really from old app I can tell.

Doesn't sync with my devices. Went back to the old app. I liked the old data visualization better anyway. Edit to respond to the developer: I don't want to troubleshoot your app. That's work and frankly what I paid _you_ to do when I bought the device. For the price of the device, the app should work as expected.

EDIT: After removing/re-adding the device completely from app it now works. History is gone otherwise works I was forced to this new app, but my device is no longer syncing. I tried reconnecting the device and it connected initially but now it fails to refresh the data. This is my second attempt at the new app. I tried this before and encountered the same problem. Back then I just decided to go back to the old app. But now I received an email from Air things that I need to move to this new app

We have 2 devices, an Airthing and an Ecoqube. We have had them side by side for over a month as well as using them apart. They aren't even remotely close in readings. The Ecoqube responds quickly to changing conditions such as an open window. The Airthing doesn't. The Airthing often goes the opposite direction of the Ecoqube as well. We have done other tests, such as running an exhaust fan at high cfm. Ecoqube responds correctly. Airthing does not. Airthing gets one star for updating software.

don't uninstall your old app. it actually works better than this one. it tells me it can't connect to my devices on the new app, but when I go back to the old one, works just fine connecting to everything don't get me wrong, I'm a new technology adopter and the new feel of the app is fine, but this app feels like it didn't go through testing. connection to devices is a key element, there should not be this many people having the same issue if the software and testing was sound b4 release.

Terrible update. It wasn't until after installing that it told me I couldn't use it with my radon detecting Airthings device. And then to go back to the old app, I had to reset my entire device, losing all my data. I guess when the old app breaks down my device will become an expensive paperweight. Horrible way to treat customers.

I received an email requesting me to install this new app and uninstall their old app. This app couldn't sync data to my air waves gen 2. After several hours of trying to get my devices to sink, I finally was able to perform syncs (by reset Bluetooth connection). However, my latest data still show yesterday to midnight. No data from today, yet app says data synced. Arghhhh.

This app is not better than the existing one it's replacing, which is very frustrating. Syncing is extremely slow (when it happens at all), and even after syncing, the app says "No recent data" and doesn't show anything for the last 3 weeks. This is with a Wave Plus. I hope things improve before the old app is fully deprecated.
