Opensignal - 5G, 4G Speed Test

easy, quick and usefull to use.

This app needs multiple permissions on your phone to measure internet speed. Are you ready to sell your privacy?

don't work 😭

awesome app with awesome features and portability!!

very accurate

best apps ever, thanks you

Please bring 6G++ services available in Bihar India as soon as possible.

best app. find Tower Location

good 👍

Giving me optimum results

good app working very well

fake app when using smart

Absolutely useless. I opened it, disabled their 100 checks per day, and refused their checks on my SIM card. I wanted a map of cell towers, not an app tracking me every 15 minutes. When the map actually opened, it showed about 40 towers along the highway headed past my house, and none anywhere else. I know that i sit inside a 5G tower's range, this app didn't show ANY coverage in my area. This is an app data mining a map rather than combining FCC and user stats. UNINSTALLED!

Simply the best.

really good and accurate,free no ads until now, awesome thanks

wrong information

good

chris bartow is hackr

It does what it says it does. runs smooth. good app.

good app 💯

very good

very bad 😞

tower location information wrong.

very helpful

patta ganna

very nice app but if you check speed again it get stock in loop,you need to close it and restart the app.

On Trial

This app rocks. It opens people's eyes.

works very well and it's free. That's best you can get thank you !

very nice but one function is missing not functioning anymore the arrow to the direction of network source.

I live in the city, this doesn't show a SINGLE tower on the map.

Didn't really work.

open signal -5,,,

good app good service

very good easy to app

great app

It is an easy to use and understandable free app. It has no ads. It's the best I've tried at locating the closest cell towers to you. Very simple, uncluttered and usable app.

ok

I’ve been using this app for a few weeks, and it’s been a game-changer. The real-time tracking is spot on, and the visual charts make it super easy to see exactly which apps are consuming data in the background. Setup was seamless, and the interface is clean with zero clutter.

This seems to be quite a good app and pretty accurate too overall. It's a useful way of checking the strength of your WiFi and mobile phone signal. I just wish it was easier to delete the history.

wish it stores data of each speed test like in an account with maximum details. and wish it shows signal quality data. and more cell tower data. wish better yet simple lightweight ui

Excellent and no ads..

shows some towers in the middle of the ocean so not particularly accurate in places but does get some correct so could be useful. app itself has a nice ui with some handy tools.

​1 Star – Broken permission loop makes the app completely unusable ​I shouldn't have to jump through endless technical hoops, clear caches, and toggle deep system settings just to get a basic app to work. After granting all required location and phone permissions in Android settings, the app gets stuck in an endless loop asking for the exact same permissions over and over. It’s a frustrating, broken user experience. Uninstalled and moving on to a better alternative.

love it

why for signal take permission phone account details its fraud sell contact details

hsidei

seems ok

nice

Very good

thoda sa aur experience badhao

nice app

very good app very beginner friendly interface and simple but really useful tools

New Delhi Delhi

ok

Very good app shows signal strength speed etc for every operator, improve video test to include 4k video test

Very helpful

Excellent

Easy ui, tells me everything I need to know about network performance and signal. shows me where the towers are.

good 👍

helped me assess coverage before switching service providers.

very good app

Bigyan nang 5 star yan hahahah❤️😘

it doesn't give me a signal strength meter

perfect😍

sinal wala

Scam

Accurate test every time... Thank you developer

good application apps

Great Apps

Works perfectly and it's really helpful! I just don't know why my phone's mobile data won't work sometimes but it's just my phone's fault. Really well done, and the errors explaining a possible cause/solution is really nice

does not work

useless

Great apps. better

great app in the world 🌎🌍

Very good and light speed test app.

It helped me to choose the best network provider for my location to switch from my existing provider. Thank you so much to the developer!!

good

it's working worth

ਬਹੁਤ ਜਿਆਦਾ ਨੈੱਟਵਰਕ ਖਰਾਬ ਹੈ ਮੇਰੇ ਘਰ ਵਿਚ ਸੱਤ ਈਆਰਟੇਲ ਦੇ ਕਨੈਸਨ ਹਨ ਇਸ ਤਰਾਂ ਹੀ ਰਿਹਾ ਜਲਦੀ ਬਦਲ ਦੇਵਾਂਗੇ ਬਹੁਤ ਜਿਆਦਾ ਘਟੀਆ ਹਨ

lovely 😍 👌

I can't update

thank you❤

Excellent

The coverage map no longer gets updated, it's probably abandoned

App is very useful

good

very supportive application and easy to use. perfect coverage results and location find out.

UNTESTED more good reviews give it a go

Very fast,detailed information,so easy to use.Actually a properly useful app !

great app period.

Nice kaayo sya gamiton bal an nimo imong speed test

thank you for making this app.love you !

Excellent app, it is so easy to tast signal.

Great

t mobile sucks I can't get on the internet I can't even order groceries I can't do nothing no no I guess I'll have to do something different look for another cell phone company

it's a basic speed tester. there are MUCH better ones available

Been using this app for years and it's always done me right!

Edit 2 - four years later the app is still bad. shame they never fixed it. Edit- issues still not resolved. UI looks nice but doesn't function. -New speed tests stopped showing up on the map but are still being logged. Reported this issue months ago without any information or fix.

great tool, but instead of only having an always-on location for sampling, should also have a check-in feature so you can send a sample, at least you'd get some sparse data points from it.

I was able to point my yagi antenna at the nearest 4G LTE Verizon tower using this app. It showed on map where the tower was located relative to my house. The yagi antenna is connected to a cell phone signal booster in my house. I ran and re-ran speed tests with the app while in my office, and ran up to the roof to fine-tune the antenna's bearing between tests. Successful installation! Would recommend the app.

This is one of the best speed test apps available, free of ads, which is why I have it installed on my phone. I appreciate that the developer prioritizes customer service over making money through ads. Best of luck to the developers; you are doing great work.

For years this app Fails by never giving connectivity failure notifications. Also, Not clear why you cannot check your cellular signal if wifi is in use. Only when you shut off wifi can you check your tower connection. Does not give you an actual average speed no matter how often you test. So what I do is first boot into the app and run the test (it won't connect), then call 611 while running the test to force it to connect and make it get back to 5Mbps.

Great for accurate speed tests. To find cell towers and signal strength, for all providers: use Cellmapper. By far best app, hands down. This is for USA. You can add your own recorded data, to the map as well. This is a big plus. Make sure to put the phone on the dash, where it can collect relevant signal strength data. (Up high, so the signal strength is best possible.)

Great app, thanks for that! 🤗 But the Network Stats is practically unusable in the app, it keeps saying it's "unavailable at this zoom level" despite it's quite zoomed out and I still have to zoom it out more and consequently it becomes irrelevant as to too large area with many cities around..., I can't get it for only one city.

Look like you as user helping them more to collect data using your device than them to help you to in return. Used the app for aprox 1 month and no change in signal mapping for my network in my region. Speed test are kind inaccurate same spot same network few seconds apart test speed difference are too high. Speed test pointer on the map is inaccurate too. Support look dead, contacted them and even after weeks didn't answer back nothing.

This app is cool! It allows you to see every single tower your phone could connect to.(keep in mind you could only see your provider towers) it also came with a handy speed tester! I'm not too sure about the follow the arrow thing... It doesn't work for me but I'm sure It would work for others! Overall great way to see my cell phone tower!

Used this app to hopefully point my cell phone signal booster in the right direction. It shows on direction with an arrow saying point the antenna that direction for 100% but the signal on the booster is still non existent. It also shows a small blue line on a different screen that is roughly 120 degrees off from the first arrow with no explanation for the difference. This app simply sucks.

It may be a good be app but this novice has no freaking idea how to use it...and you're no help. The maps are too dark to read and I can't even find how to lighten them. Surely there must be something easier for us 'dumbys' to locate our cell tower locations. Also...I use a mobile hotspot; will this app work for this device also? Sorry, but I'm thoroughly frustrated with technology at this point. Just give me 2 tin cans & a piece of string again.

I've been looking at a number of cell tower locators and this app blows the others away. It seems to show me all the cell towers even the ones I'm not connected to plus it shows me both T-Mobile and Sprint but not at the same time which is puzzling nevertheless show me the location of the towers and having an arrow that points in the right direction is far superior to any of the other apps for cell tower location

It's a vaguely useful app for checking network coverage but it's a battery drainer and the coverage maps are surprisingly really poor with only a very small number of dots on the map in most areas that show general coverage. If you zoom into the map there aren't enough data points from individual operators to be of any use. Other similar apps are better.

Good app and gives accurate speeds unlike other apps which shows good speed of Jio (10-15mbps) but practically it has poor speed in my area (1-2mbps). Only problem is it refuses to change my network provider to BSNL when I change mobile data to the other sim for measuring it's speed. So I am giving it 1 star rating because it is not changing even after uninstalling the app. Please add dual sim support for God's sake.

I couldn't recognize OpenSignal when I reinstalled it. It's like someone dropped 95% of the useful features and made it into your below average run of the mill test app. Even basic configuration, like how many times or how often I like the app to rest isn't available. Are we supposed to move over to their Meteor app now?

lady and gentlemen, I would say this app really good. This app will lets you know what cell tower you're connected and guide you to that cell tower too. One more good thing is that can show 4G booster locations too. You can find out who's are using 4G booster to floating 4G signal in you area. Awesome.. right?

I would like to see more transparency of when the maps are updated. Also I posted a review of this app in 2018 stating that the cellular "heat" spots on the map are two small to be realistic. I still strongly feel that way. *Would also be FANTASTIC If the maps would differentiate 5G from mid-band & mmWave. Or at least 5G and Mid-band/mmWave combo. It's understandable if that's not technically possible. But if the phone shows a 5G UC (or equivalent) I would think that data could be harvested.

It works well in some cases, but I recently spent a week where there was good 4g/5g coverage by some carriers, but not mine (T-Mobile). The app said I had 100% network connectivity, but in reality, it was about 90% "Emergency Calls Only". I could only get real service in a very limited portion of the park. The app could not distinguish emergency service (911 service) versus actual service that (for calls texts or data). The apps utility is extremely limited without that distinction.

I used it several years ago and it was good. Now it's an mainstream app that doesn't show all information... And collecting data can not be changed, either 100 times a day in the background or not at all, why not something in between. It can be used for Speedtest, but just use librespeed test in an Browser.

Simple and accurate, especially when you want to know how much downtime your provider does to your monthly data in total. If this feature become more solid with valid log, I'd even pay the percentage to the developer from the compensation I got after the settlement from provider for their disintegrity to fulfill their service contract. Let me know if anyone else is in agreement, so that we can have a better bottomline.

The new app has hidden and over simplified the cell phone tower locations map. This was an important feature since phones often use multiple towers at once with Dual-Band Dual-Cell HSDPA. Now it just points to the closest tower. If no one has already tested in that location (often happens in remote areas) this make it more difficult to figure how to get the best signal between towers or for planning a trip in advance with the inability to choose a different location and the lack of information.

Does not track well. I allowed it to use my location all the time. I was really hoping this would actually record data accurately. It does not. I went for a drive for hours today through the rocky mountains in Colorado. There were many times I had no signal. It still hasn't recorded a single time I had no service. There is simply no point in doing this if the app can't do the one thing it was designed to do. Fix it or forget it.

Although the app has a considerable array of features, it is still simple and straightforward to use. Furthermore, one of the reasons I'm giving it five stars is that there is no shortage of explanations for the technical terms having to do with telecommunications, wireless signals, data streams etc. I was never bothered by any ads, and the physical functionality of it and the extensive database of coverage maps is not lacking at all, in my opinion.

In a dual SIM phone, the speed test report assigns test results according to SIM 1, even if SIM 2 were used for the test. I get pretty good speeds on AT&T (despite getting LTE+ only on my unlocked phone) so have that SIM in slot 1, but once in a while I want to figure out if T-Mobile 5G has improved to switch to SIM #2 for a test. These dismal results are then attributed to AT&T. Likely this means that OpenSignal's entire dataset is suspect.

Does the same job as any other speed test app. Gives you fairly accurate and consistent readings when you compare with the likes of Ookl***. But the part where OpenSignal beats its competitors is that you get ZERO popups and ads. For this reason I uninstall Ookl*** and will now only ever use OpenSignal. Also they have a VideoTest utility within the same interface that gives you stats for streaming video over your network connection. AGAIN NO ADS. 5 Star app and would recommend to everyone

Works as advertised- perfectly! Not 1 single issue in a couple weeks worth of usage. Nice work on the app. ...it could use a little revision as far as getting the functions to be a bit more obvious on-screen and the ads would be more tolerable as a small banner on the GUI. Just my two cents. =)

There is a tower 3 miles give or take from my location and the arrow doesn't point to it just spins around randomly and depending on how I move my phone upright or flat and up in the air or down towards the floor.... also doesn't show any towers on the map.... which is the only reason I got this app to try and instal a wifi booster.

The tower location is approximated by the data provided, other apps allow premium users to actually refine the location to where the antennas are installed. If you think the compass will point you to the tower you're wrong, it will point to where the signal is stronger and can be just a temporary strong reflection. On top of this there is no way to see the coverage map from a PC.

It doesn't detect the presence of a secondary SIM and so the carrier information of any speed test run from it is wrongly detected. For instance, I have two SIMs: Jio (SIM 1) and Airtel (SIM 2). Mobile data was on for SIM 2, which is Airtel. But, this app wrongly detected its carrier name as Jio. I'm sure this would lead into incorrect carrier reports at your end.

This app is a good app to have it allows you to check your data the level of data your consuming test your download and upload speed and if your not shure if your wifi is working on your device it makes it alot easyer on you just open up the app a thay also have a map that gives you the locations of the local carriers, works really good i always download this app on all of my devices 📡🔎📐

I've used this app off & on for at least 10 years, since 2010 or 2011, loved it since I 1st found it. It is accurate, the app is easy to navigate, it doesn't take a rocket scientist to understand the graphs & data, & I have found no better or more reliable app to help locate your cell towers in your general vicinity. And I have purchased the upgrade in the recent past but don't know how to get it back after factory reset. Even still, excellent choice in an app of it's type.

I rarely rate apps yet alone leave comments. I am just so impressed with this app that I felt I had to. First of all, it is very user friendly. You do not need to have any technical knowledge in order to benefit from the information it provides. Each tool is well explained in the app. Thanks to the developers for a phenomenal job! I'm looking at the extra thought developers applied when choosing what to download now. Can't say enough good things about it! Not even any rotten ads!

Inaccurate cell tower locations data. It thinks cell towers are at residential locations. I tested by going near those locations and my signal does not get any better. Other sources and apps save the towers are much farther away and when I go to those my signal gets better. This app's data is inaccurate. It's kind of weird because it lists the towers' IDs and everything.

So far so good. Nice utility for your cell tower location as well as most other locations by cell company giving data on latencies and download/upload speeds, location, direction of tower and more. Other utilities include speed and video stream tests. Not a bad set up. The only complaint is there's no legend for the coverage colors. But that should improve with time.

One of the best reliable Mobile Network (3G-4G-5G) Speed ​​Test and Cell Info APPs. I have been using this great tool since it was first launched to the Android market (Play Store), I bought it and it never dissapointed me. This APP is getting better and better on each update, and is constantly being updated. Good job, Guys! Please keep it up! Thank You! ツ👍🏻 • One question ⇨ How can I delete Speed/Video Speed Test History Log manually without clearing data on Android APP Settings?

I downloaded this because I didn't have any signal at a family members house, after I downloaded this app I was able to maintain a constant 4g signal while upstairs wherever I had my phone. I deleted it after arriving home and just re-downloaded it because one of the apps I use keeps saying "reconnecting" I usually have 1 to 3 bars of 4g or 1 bar of 5g but the app requires more service so I'm hoping it will help the app work better.

This app is easy to use. You can find out how strong your signal is with a push of a button.Find out what towers are in your area, and which one you are getting your signal from. You can see what cell phone providers are strongest in your area (Verizon, AT&T & T-Mobile). The only thing I wish I could do with this app is to change which tower I'm using when I have a weak signal just to see if I can get a better signal. Besides that I'm really pleased ☺ and happy with this app 😊 2 thumbs 👍 👍up!

I don't understand what this app is for! The name "Open Signal" I thought was to crowd source and make mast locations more accurate. But after months of submitting data the mast locatiions are still miles away and in the wrong direction from the location I know they are located. Seems a total waste of time and should be renamed Closed Signal, because there is nothing "open" about this app or project!

The speed test, was less accurate than I'd hoped for, however the cell tower location, despite being in an extremely rural area, was spot on to the location of the nearest tower according to the carrier, and having the tower 'compass' is very beneficial for installing a repeater.

Had barely any signal & I think I was getting throttled but as soon as I checked out my network it didn't do right but within minutes got amazing speeds which I paid to get.Got 25 gig at 4G then slowing after but it was so slow only got to use 6 gig all month until now ! I guess they get away with it till you check them out to see what is the problem is

Dear developers. I've tested your app in St.Pete (Russia) and considered it as useless because of the folloving reasons: - quality of mobile network could be tested by Speedtest by Ookla. There is no need to install your app; - location information of cell towers is useless because non of actual tower locations are marked in my region but i've got many fake locations. Some of them are in Neva river.

Seen the app change over time, used on several devices. Developer please do not go super user friendly. Always keep advanced features available for people who want more details/more stats. You have a good app going and are doing good work. Cell towers map can't ever seem to find cell towers STILL, after all these app updates. I keep hoping one day it will work. Obv the lack of ads and nagging for ratings is a pleasant plus. Whole heartedly support you!

It does some things I'm not interested in. The tower compass is what i would like to see function properly. It never has for me. In one place i was able to use it because, like another review, the arrow was the opposite of the general direction i knew the tower to be. Would be nice to be able to use this to focus my booster, but can't trust it.

It provides false network stats. I was using Vi, but it was showing that airtel and jio are faster than vi in my area (Jalgaon, Maharashtra,India), then I purchased jio and then airtel, experienced them, did the speed tests, still vi was much more faster than the others and also this app is unable to detect the sim card company while doing the speed test.

Love it. Just checks the connection strength, very consistent, and I really like the simple but refined and easy to nav UI. It's nothing spectacular but it's made to do something, it does it, does it quite well, and quickly gets you accurate information that, ime, providers lie about or will just not fix something unless you complain. Sometimes not even that. e

I've been using open signal off and on for many years. I love the concept and the information is very helpful. It would be nice if the follow the arrow feature had the north bearing on it. When comparing the follow the arrow to the tower association map, they don't match.

The app is overall good. Found no major bugs/issues. But one major thing that I'm fed up of is that it uses only slot 1 for checking out the towers. It should also operate for slot 2 as well. Like there can be an option to select for which we want 🙂

From our house we can barely connect to any network so I bought a signal repeater. The antenna has to be pointing to the network tower so my purpose for this app. Surprisingly, there are a lot of towers showing and I know there isn't so much of it in our area. What's so funny is that there are more or less 10 towers showing that is in the lake waters nearby. Also the signal finder will point you to a direction where there isn't any tower. 😂🤣

Not sure if I can trust an app that skips frames during the test but still gets a really high rating with no buffering. Maybe I don't understand the test but it was taken when the video that streaming was buffering at that same time. Weird. Getting no better than 2mbps but it's telling me I'm getting 8. All changed at last second. So I downloaded something 2.5mbps app still says 8.

Works as a speed test app only. Has never monitored signal quality on any phone I've used it on. It says that it does, it says "it takes some time to collect data" it has a setting that says it will collect data 100 times a day. But it never does. So I don't know how it's signal maps can be accurate.

If we are to believe the coverage maps from carriers I shouldn't be getting just 1 bar outside my ofice. By sharing the signal measurements collected by this app you help get at the truth. So that we can all make informed decisions about our mobile services. The app works. It's free and has no intrusive adds. 5 stars deserved. Update Moto G7 Android 9. Does display the data signal whether mobile data or wifi -1 star for the unresolved bug.

Removed ability to export the data to the SD card randomly for no reason, and also just stopped collecting data, so the network availability chart for the last month is just at 0, neat. So now after they updated the app to a new interface, there is still no export option and it just doesn't even work, android 10, all permissions granted, 0 measurements after a day. Save your battery and don't install

Botched reporting. When poor performance of network, it will not complete test, so no reporting of bad services. But else when you move to better coverage, then it will automatically collect data in the background, to show that network operator is performing on top. Seems sponsored by specific operator to always keep it on top.

This was my go to app and I would recommend it to my family and friends. Now, this app just plain freezes up especially on the upload test for mobile connections. Wifi is less of a problem as it happens 30% of the time but I got it mainly to check my mobile speed. I thought that it was an old device and android 8.0 issue but I have tested it on new devices running Android 10.0 and still get the same problem. I have uninstalled this app and don't recommend it to anyone anymore.

This app is junk. The cell tower map is hopelessly inaccurate and even shows that my device is connected to a 3G tower even when it is actually connected to a completely different 4G tower. Well it's a free app without ads so I guess this is to be expected, but what's the point of providing free ad-less apps like this if they are useless? LJ, Norwich, UK.

Everything is very buggy indeed. I wanted to check the coverage maps of different providers like Airtel, Jio, Idea, etc. But in the coverage maps section, the menu for selecting the carriers disappears or shows ony a single option i.e, 'show all'. The menu loads sometimes and immediately disappears. It is very frustrating to use the app especially the maps section. Please rectify it at the earliest. If it was fixed, the app deserves a better rating.

It works great except for one thing that is about utterly obnoxious. If I am somewhere without service it will constantly ask to search for an available network. It doesn't give the option to disable it in the app or give the option to not allow "show over apps". It literally pops up every 10 seconds or less. I love the rest of the app, but it is getting uninstalled because of this. I've had to close it over 100 times to write this review and I wish I was exaggerating.

Very good app, it isn't ad based and doesn't try to be showy. Shows you exactly what you NEED , in my instance it's the area signal for my network (UK, 3 network). Best part is that it accesses signal strength from one device to another i.e. tablet connection to WiFi via my phone's data.. great if you don't have home broadband..

A week into this now. It still says no information available . The app also does not tell what company owns what towers so you may see the choices. It does appear to have a real time arrow pointing to the tower you are allegedly connected to but again, no way of knowing who owns it. It does not tell you after both speed tests it offer if your results are good, bad, or indifferent. The average layman could not possibly decipher whether the numbers given for yp and download speeds are good.

App is useless!! It shows a map and pre added network list and the average speed experienced by customer. If you zoom in your location, it will say network data not available after zooming in !! If the app doesn't let me zoom to my location, how will I know the exact speed here ! Doesn't show any tower location or any such information. Average speed shown is also wrong, I guess that's because application doesn't let you zoom to your location, and shows overall city's speed !!

Mediocre. Not nearly as good as Sensorly was before it shut down. Ads have been removed and the app has been greatly improved, thanks! There is no measurement mode. I want to expand signal maps at the time of my choice and have zero battery usage and privacy impact otherwise. Useful, but I'm looking for something better.

It is almost an excellent App if the minor mistakes are overlooked. It shows the direction of the router and gives a good indication of Latency, Download and Uploaded speeds. I recommend very much to install it. After almost 5 years, I changed my mind. I will uninstall it.

It does not give the info it claims to. It's zoom in, zoom out, over and over never ending. Needs instructions if it truely does all you say. The only info I get is the speedtest sometimes. I believe this app was not developed to give info but take info from downloaders for only their own purposes.

Lots and lots of useful data, such as latency and signal strength comparison between all major carriers, cell phone tower map (and names), speed tests for wifi and cellular modem speeds and, last but not least, detailed coverage maps. Also had a cell tower compass but I'm not sure how useful this feature is...

This app use to be good but now ig never shows where the cell towers are no matter how long you let it run for it just says searching, the only time it did actually show a cell tower that one was about a mile out to see. I know where all my towers are in my area and i know for sure that there isn't any out at sea, it also gives false speed readings now where it never use to. Please take time to make this a good app again! Ookla gives a far more accurate readings on speed tests than this does now

In all the years I've been using Android phones and apps, I've only rated 2 other apps at all. An app really has to be exceptionally good or abysmally bad to get me to put forth any effort at all in telling others what I think. Here is what I think: EVERYONE NEEDS THIS APP! It's so perfect in it's simplicity. It gives exactly what I want quickly, accurately and with almost zero effort....FOR FREE, AND there are no ads!!! I could seriously hug the people behind this app!!!!!

I think this app is designed for the benefit of the networks rather than users, to make their coverage look better than it is. Stats are completely false. I struggle to get a data signal at home, yet the app shows my connectivity as 100%. Take any info from this app with a pinch of salt. Use Ofcom website for more realistic network coverage in UK.

I'm rural for 3 years now, and the network coverage maps from the cell companies are total lies! I was hoping this app would help me find who has better coverage in this desolate area. So far the tower location maps on this app are wrong, there are no att towers, or any towers where this app says there are. I've physically gone to the locations where the app maps them. I also can not find a way to check locations of the other networks as I'm on att and this app only shows my providers towers.

An incredibly useful app. Essential for all of your devices. Accurate speed tests (mobile or Wi-Fi), locate towers, compare your carrier to others in your area, see how your coverage will be when you travel, and more. Excellent for troubleshooting network problems, testing performance, or simply to learn a bit more about mobile connectivity. *Remember, the maps and data are crowdsourced. The more you use it, the better the data will be, and blank map areas will be filled in & more accurate!*

Manage phone calls and SMS??? Can't see any good reason for this. How can user be sure you don't read contact list, calling list, and SMS? Is these 'reading' really Related to measure internet speed? How? Why? Suspicious to say the least. User beware. Edit, top right side 3 dots, Flag as inappropriate, and give your reason. Maybe we users can stop this nonsense spying on our call and sms log.

Use "Network Cell Info" instead. OpenSignal isn't accurate in showing which tower exactly the app is connected to. "Network Cell Info" will display way more information, plus let you know any time a cell you're connected to changes. It also displays the signal strength to a second best tower that the radio can switch to at any time.

This used to be a great little app. Now, sadly, it has regressed. As others have reported, the cell locations no longer show on the map. Also, I no longer see advanced information, I can't see the option to export my readings and I don't understand how to control the data usage (so the speed tests eat away my data allowance). So, time to vote with my feet. Let me know when you make it as good as it was 2 years ago.

Last time I tried this app was a couple of yrs ago and the cell tower locator didn't work.Now 2 yrs later I dl'd on a newer phone and again the cell tower locator isn't working. It keeps saying it's searching for towers and never shows anything. I remember several yrs ago in 2014 or so it used to work.It would draw a straight line from you to the current tower and all other tower info would pop up, along with their network. Why does this NEVER work anymore? Coverage & speed test work fine fyi.

main thing I was looking for was the cell phone tower map. it's a bit tricky to find the button to bring up the map, and once I bring it up, it doesn't map any towers. I've moved the map to areas i know there's towers, zoomed in and out, and nothing. there's an options/info button, but it always says 'still searching for towers, wait till towers appear on map'. I've left the map open for 45 minutes to an hour and no towers are ever found.

Best app. I was with Flash Wireless on the Sprint network and for months I had horrible reception, although the signal strength was showing 3 bars. When I downloaded the app it started pinging the Sprint tower and reception improved for a week and then it was horrible again. I changed to T-Mobile because of this app. Now, I have improved service. Thank for you this app.

It's hard to write feedback for this app, since it's best to comment on each of the various tools within it, but overall it's got issues. The so-called cell tower locator doesn't work where I'm at. I'm not sure what it is depicting, but it's not cell towers, and it doesn't even correctly show my local towers, amidst all the random points appearing on the map. The coverage map is also quite inaccurate (and incomplete). Perhaps it's just not good for rural areas?

It works to an extent. The tower locations are very inaccurate. Going to earth or maps and looking at satellite views at the location where the app says there is a tower usually shows no tower. However speed tests and coverage are pretty accurate. To everyone saying that they can see a tower but its not showing up on the map. Therefore useless. Towers arent just built for cell providers...

Doesn't work in my area. Seems to have me connected to towers in the middle of the English Channel that I don't think exists and the compass points in a different direction to the tower it says I am connected to. The signal strength is sometimes shown as 5 bars on the app and 0 bars and a 'no service's notification. Update:3/4/2019 seems to only have a speed test now so can not be used to test mobile signal any more (wasnt that the piont of it?). So bye-bye.

The Open Signal Widget disappeared after the last Open Signal software update. I have been using the widget for over 10 years. In my opinion the widget makes the app so much more useful, as I know at a glance what speed I'm connected at, the signal strength, and direction to the tower. Please bring it back. I have changed to a different cellular network info app in the meantime, and have uninstalled Open Signal.

Good easy to use uncuttered UI nice and simple, we don't need to see a mass of numbers and parameters that might be useful to a telecommunicationns engineer I just want to see where the cell towers are for my network and the signal strength, this app does exactlyy that, also has a pretty good speed test facility as well ........ ' Recommended' !

Sporadic updates keep me from rating this app higher. My data doesn't seem to be getting used. At one time the map was getting updated very roughly every 6 weeks, but it has been almost a year now, the old data has aged out, but none of the new data I have collected has been added. Also, the algorithm for locating a tower is pretty inaccurate. 120.degree sectors appear to be separate towers in completely different locations, some of which are out in open water, which is impossible.

excellent, there's one feature that comes & goes though. I live in the country, lots of trees, so signal is spotty depending what road I'm traveling. The app tells you which tower you're using, but on the cell tower map I don't always that visual line from my location to the tower I'm hitting, & I like to see when I switch from tower to tower. Because some of them seem to be better regardless of their distance from me.

Saved my whole trip to 4 corners and Midwest USA. (Apparently Verizon network isn't regularly carried there like the coasts). Lets you select local towers for better bandwidth and optimizes as you travel on roadtrips. (Typically you'll be attached to the same one you've picked up on the way through until at extremely low connection [below zero bars] before you're device picks up another one.) So basically it's amazing. You can also check your ping, down and upload speeds, and even which direction to find the tower you're closest to ASAP, even before activating the Google mapping service to find it (very useful in situations where you need to make an emergency call, and have poor connectivity, wherein you can't upload a Google map anyhow). Awesome app. A must! 5☆ all the way. Also uses nearly zero data. Doesn't run constantly in background. No ads even in free use, and only takes about 20 megs of hard drive space (way less in RAM). I recommend this app to everyone I know. Please use it. It's amazing, without trying. :)

OK if you want an idea of what network coverage is like. Regarding cell location and signal strength it falls short. On my phone/network it shows the the tower it expects me to be connected to, in the list of cells and on the map, even though the compass is correctly pointing to a different tower.

Amazing app, very useful for comparing networks and speeds in different areas. I've used it for years. However, lately the speed test seems inaccurate. It always used to provide results reasonably close to those of all other testing apps/websites. Lately, it has been reporting speeds that are more than twice as fast as other sources. Realistically, it could theoretically be T-Mobile recognizing the speed test traffic and manipulating results to provide a better network rating on the app. It would be interesting to know if other users from the same, and other, networks are experiencing this is well. It would be quite the scandal if this were occurring.

It's not exactly 5 star. It has some issues, but it's an indespensable tool for us as we travel and work so I gave it a 5 anyway. One thing that could be fixed is that when searching the coverage map it could put a marker at the address you are checking.

I've used this app for at least a year. I'm a huge fan of crowd sourced metrics. So being able to see carrier stats based on location is awesome. There is a feature I don't really understand, and that's the compass tower finder. It's never pointed in the direction of a nearby tower. One time, being close to a tower I was curious to see if the app pointed to it and when I opened the app it was pointing in a completely different direction. I could see the appeal, but I haven't seen it work. Last thing is recently my pixel XL has stopped reporting stats. Not sure if it is the new Android version or not but if I close the app, and opening it again sometime later to view my stats, it starts from zero like it hasn't been on.

For many months I have been working on which company provides me better and reliable cellphone coverage. With this app and some little effort, I was able to obtain a real network map to apply it towards my personal commute areas and their actual speeds. There is always room for improvement, but once again. OpenSource and Zero Ads.
