OMG IS SO GOOD I LOVE HOW THAT IT CAPABILITY DIDN'T MATTER

Great app, does what it says on the tin

Best in calculator as its tittle says and the developer support, is top-notch and easily earns 5 stars.

No problem for this app, it is my daily use.

आल इन one calci

This calculator app is very convenient, visually appealing, and easy to use—anyone can use it without any difficulty. I really like it. I would recommend this app for daily use in offices, schools, or for business-related tasks. You should definitely install it and give it a try.

Good! I love it so much. I am yet to find a mathematical need I have not been able to solve with this app.

Easy to use. Accurate

very good

exceptional experience

it's all in one app easy to use and very convenient

maybe add stuff for students in algebra 2 to college senior level math

Best calculator by far

this calculator is great but could you add rectangular pyramid?

Love all the included extras like currency, distance, height conversion and many many others which I hadn't realized would be so handy so frequently 👍🏻🙂

good experience.

very very useful for me.I like very much. Thankyou

great app has many useful functions.

like the best calculator app there is and it is not just numbers you can check age,speed etc

super,super,super

Why do i need an account for a calculator? why do i have to go trough 200 companies begging for my private information FOR A CALCULATOR? why are there ADDS on a CALCULATOR??? WHO EVEN USES A CALCULATOR SO MUCH??? A PLASTIC ONE IS 5 EUROS!

cool app (got nothing else to say)

I paid for lifetime on Dec 1, 2020 and now i installed on new phone but the app doesnt recognize the purchase and its asking me to pay again. Now my question is dear developer is your "lifetime" really lifetime or just "time". It was more than 2 hours i installed, the phone is connected on the internet over mobile data + wifi of my land connection but still nothing. Same as clicking on "Restore purchases" does nothing. Fix it.

After buying pro lifetime. It shows ads and asks me to pay more.

I use this when I think calculator.

This has been my go to calculator for many,many years. When they added ads, I decided to stick with it but I can no longer put up with all of the ridiculous ads. Ads pop up while I am inputting calculations and there is no way to get past the ad quickly to finish my calculation. Sadly, I am now on the hunt for a new calculator and am embarrased that I have recommended the app to so many people since they have made it so not user friendly.

This is such a useful tool! It's an amazing app with very robust features. I recommend this calculator to everyone!

yes there is a very small ad ribbon at the bottom but it is NOT intrusive in any way. I had to go back and look to make sure it was there. It has been a wonderful math tool for me. Thank you so much for all the hard work and effort everyone put into this app. I recommend it highly to anyone that is taking a math course in highschool or college. It will truly amaze you. Thanks again and God Bless you all

great except should be able to fully clear memory

if it all in one THEN WHERES ± AND ≠😔✌️ 2 STARS

I love this app, it works well for everything

the app is so good but the ad is comeing in between

Nice!

Disappointed I purchased what I believed to be a lifetime license for this app in the past, but can no longer restore my purchase with the in-app option to do so. I've been unable to contact the developer or get support for my purchase from Google Play. FWIW, I loved the app prior to this issue, and would gladly revise my review if I'm eventually able to regain access to my prior purchase.

very good

soft in use

This app has everything you need measure wise, including a calculator all in one app. Easy to use and toggle between features. Update: The ads are getting not only more frequent and annoying but freeze and you need to close the app and reopeng to be able to use it. Update: Will search for another app. This one has gotten excessively aggressive with ads.

Best of the best

Great tool, you can calculate anything and it is very easy to use. You did a great job Team👌👍

so good so indescribably good

I find it pretty funny that you can have an account on a calculator app but either way it's a very useful app

has everything u would ever wanna calculate its good

It's a calculator

I had 5 apples and gave my friend 2 apples but I couldn't figure out how many apples I had left, this app helped tremendously.

Bonne Appli

nice and good

It is a very good app if you are a student I am recommending you to install this app now it is my main calculator there are not more than 5 stars if there were I would give it like infinite stars and there are also not many ads I am using the normal version but still it is very very good.

I paid for the 'pro' version of this app a while ago. Installed it on a new phone this week, and it's riddled with intrusive ads. The 'restore purchases' option does absolutely nothing, and no response from the developer. The only option is to pay £11.99 to get what I've already paid for before. Really shady. Uninstalled.

unable to restore the purchase. nothing is happening on click of restore purchase.

খুব ভালো একটি অ্যাপ

Very good calculator. The best in my opinion.

Nyc app

Easy to use and very helpful.

very useful all-in-one calculator app. 5 + 1 stars 🤩

This thing has everything! even more than the good old phone calculator!!🤯🤩

a very useful app especially for my children. love it

Disappointing customer support! I purchased the Lifetime Pro version in Nov 2020. After changing my phone, ads reappeared despite my paid purchase. I have emailed the developers multiple times since August 2026, providing proof of purchase, but have received no response or resolution. Paying customers deserve basic support and the benefits they paid for. Prospective buyers, think twice before purchasing this app until the developers resolve existing customers’ issues and demonstrate they care!!

mtsken. sfabf

all in one calculator can claim the google play pass

Nice app for all use and does not have that many ads

hello and good day am having a a issue with this great app ok I bought lifetime premium and the app won't allow me to restore my premium

It is a perfect and best app for calculations.I love this app. There are all languages. In this app there are many important points and factors that helps me learn more about maths. It make tough possible problem into easy. It is a little bit hard to convert number into another from it is nice to use.

I use it often and it suits my needs

very good experience

It's a good app, and I'll send it to my friends.

This app is great, It has a lot of a lot of a lot of conversions, more than I expected, would've been 5 stars. The only thing I'd say is problematic, it's the UI, it is a little bit complex because everything is just so far away because if you want to find something, sure there's a search bar. It's kind of still a little bit, I don't know, I just think it's not too perfect, otherwise I would have given a five star. In summary it's a must have app.

Used this app for years and it was fine. Recently they made the ads way more aggressive, and more importantly the type of ads have changed. I now get "ads" that say "Your computer is broken click here to fix it", basically phishing ads. Because of the security risk I am uninstalling.

Why are you installing this when you can search on Google?

This is one really handy app. There's no wonder why it has earned an Editors' Choice. There are lots and lots of unit conversations and even a very able calculator to boot. This one has definitely earned a place on my phone. Thanks, Andrei, for doing such a great job with this app. I can't wait to see what you pack in next.

this app is sooooo good whoever created this needs a prize I have been looking for a good app that does evreything well I found it

This calculator is great for all your needs.

this is everything you want your calculator app to be

I used this thing for years, it's absolutely perfect

wast responding app iam impressed

great

the app is easy to use. has a lot of handy features for converting and comparing calculations.

it was really good and fast and I guess it didn't warm my phone e

I really like this app

It's so nice

Why does a calculator need account signin? Also I purchased lifetime pro years ago but now restore purchase doesn't work and you're trying to force people into a subscription, for a calculator.

awesome and very very useful app...

Good

i swear i saw an nsfw ad…

Has everything you need

perfect

Not bad but could be more dynamic design

👍👍

very nice app .

very useful app

👍🤩👍 Super grrreat! Love this app! So practical & handy, lots of options easy to maneuver. Have been using it for many years & they've even improved on it, if that's possible!

this is seriously the best calculator app there is. there are very few ads, it has a clean organized design and is very easy to use. I love that I can find the volume of a shape very easily and the history is very helpful. the best part by far though is that it can show you how the answer was found and how to do the formulas yourself.

n/a

perfect

it's a good app.. does tons of different conversations and almost any math if you know how an advanced calculator works. can get a little tricky but your good once you get a feel for it.

ultimate

great

Besst!

Helps me cheat

Subscription model to remove the ads on simple calculator app is ridiculous. When they introduced the full screen ads, I stopped using the app for its main purpose

Best app

I can live with ads but I am offended by a software developer who allows scammers to advertise in the app. I was confronted by an add that said that I had 92 viruses on my phone and needed to install some antivirus package from Google Play right away. this was all BS and a scam.

One of my most used apps on my Moto G Stylus('24)!! I love it! I often use it for conversions and just used it for data storage to find out how much storage I need to back up my phone! 09.2026 UPDATE I still use this app almost daily! it is hands down the best calculator app! ONE Request ABILITY TO CHANGE FONTS & COLORS!

Graphics is kinda mid Great plot tho

The app is excellent 👍. Keep up the great improvements.

👍👍👍

Very good

Clean interface and full of functions

Excellent app

Used it for a few days and do far I can say the app is great

great app

i like this calaculater bc it has a lot of options but i want you to add more thing and themes layouts- themes: Dusk (navy blue and black) Matcha ( Vibrant Lime ) System Calculater (Defualt calculater you will get in a phone theme) layouts: Basic, Advanced, big screen, rectangle and also add more math tools please

I've been using this app for years simply because it does everything I need and plenty more. I bought the lifetime version in 2017 because it was perfect for my needs and well worth the money especially with such good customer service. (I've had one problem in all that time and it was sorted with a quick email).

Edit: intrusive full screen ads that are hard to exit out of are not appreciated when I just wanted to use a regular calculator for a few seconds. Old review: I appreciate the instantaneous conversions into multiple units. Super handy that it's integrated with a built-in calculator.

very good calculator. HAS NO FRACTIONS. Has everything else. Different currency. Every currency there is.

This app so 10/10 it's not just a calculator it's a cultculator that can just out of iPhone!😂 it helps u with all saoghts of math agabra division area and ETC....MORE I'm never deleting such kind of app Ever.

I use this app more than I thought I would. great app

best calculator app! huge recommend to anyone. I use this all the time and it's way better than my phone's stock calculator

I give only two stars because ALWAYS THERE IS ROOM FOR IMPROVEMENT 👍👍👍

very good

This app has loads of conversions. The ones I have used include length, weight, pressure and fuel consumption!

I found the categories of templates very useful, as sometimes I'm not sure exactly what to call the type of equation / formula I need. they offer quite a broad list of solutions for almost any need. So many that scrolling to locate each time might be tiresome, but they thought of that, too. Even on the free membership they make available a favorites list for formulas that I use most often. That is a great feature! Also, the easy to read layout and the button to review history.

superb 👌

Satisfied!

good

love it

really good 💯% recommend for all

❤️👍🏻🌹🤝🏻 ما شاء الله

it's a good calculator

it's great and has everything very helpful

This is a really good idea if you can get the weight out of the equation if you can get the weight out of it.

It's quite a good app

easy to use with many options

I don't like the fact that it's most BASIC function as a simple calculator can't seem to work without internet connection.😑

Convenient being able to convert everything in a single app. Thank you.

truly amazing 👏

this app is really good great actually I can almost caculate anything 😊

It's a calculator. It does calculator stuff. 10/10.

this calculator can be very helpful to college students if there colleges allow mobile but nevertheless it is very incredible for daily study use

its very good cal

I really like all the features it has. It's a super calculator as you can calculate just about anything. You can also change the colors to a theme that you like.

azaming

good 😊

we need more people like you vro 😂

Monthly subscription for a calculator. Absolutely criminal. The internet is dead.

before using it the 1st time, i had to consent for hundreds of cookies and partners who needs access to my data. otherwise I need to scroll and disable them one by one. no tnx i didn't consent neither tried the app. uninstalled. tnx

good very usefull

👍

vary good

The app is definitely worth it. Having all the different functions at my disposal without having to wait for a bunch of websites to load is a real time saver.

all fine, just one question: what does the % key do? it doesn't give me the % of a thing. It turns a % into decimal. 5 '%' results in 0.05; While on other calculators 1 / 2 % results in 50%, here it becomes 0.02

Great multipurpose calculator app

Lovely app mate.👍 ( I'm not British. I'm just larping )

Love this app. It has everything that you need. Say goodbye to those pre-installed calculators. I know you can't delete them so uninstall thier updates and disable them.

Works exactly as it should!

Can't restore my previous lifetime purchase/ subscription from before.

nice

very good calculator modern for this age.

good

This calculate changed my life😭

I purchased the lifetime pro license back in 2020 for $5.43. Following a recent price increase, my license is suddenly no longer recognized as valid. Honoring a lifetime purchase shouldn't change when your pricing model does. Disappointing customer support and business practices.

Amazing and Simple Ui too bad another PAID app 🥱🫤

great app

its really useful, thank you so much to whoever made and thought of this🙏

nice

I got the lifetime pro version of this app years ago because I believe this to be the best calculator I'd used up to that point period. For some reason I no longer have access to it. Hitting the "Restore purchase button literally does nothing and I'm starting to think that the devs just wants another purchase. I really did love this app and found it useful. It would cost 3x the amount that I paid for it and I find that to be insane. "Lifetime" is supposed to mean LIFETIME!

One of the best calculator apps I have ever used!This app provides more than enough types of calculators, making it incredibly useful for different calculations. I’ve tried many calculator apps, but this one stands out as one of the best.The app icon design is also 🔥 and looks really attractive. Another thing I appreciate is that the app doesn’t show ads very often, which makes the experience much better and less annoying.The customization section is also very useful. I will recommend others.

this was helpful seeing as the calculator that came on my phone didn't have most fetures

Excellent app, but in the calculation part of solutions, you only show the calculation step, which is important; but it will be smart if you start with the formula then to steps of calculations. Thank you.

This is one of the best calculator app I ever saw with conversions so much more!

good for budjeting

An amazing calculator app for my tablet that didn't come with a pre installed calculator for God knows why🫰

With any new device I get I immediately download this app. It has so many more options compared to the basic BS that's pre installed on devices.

Works just fine, like the conversion functions

So far I like it. I'm not using it for any math wiz stuff. I left the Texas Instrument scientific calculator with a younger student when I no longer needed it. But I do like how it is designed and operates.

amazing tool. makes my job and life much easier. Having access the vast conversions. love it

Good calculator app. Has a good UI and is customizable. Number format can be changed. There's also a feature to sign it to save favourite math functions like currency converter, body mass index etc. The advertisement is at the bottom of the calculator. No pop-up advertisement.

Technical

I am a student, and I downloaded this calculator app for my studies; however, its features are not limited to academics I can use it to solve complex scientific problems and apply it to real-life situations as well.

it is very good

Great, but it doesn't have a Graph calc

💪🏾

Marvelous! It a two in one app, converter and calculator. There's a mistake.

Good Super

how to find bifer cation of 555days in year month days or months or years also

ads in a calculator app is crazy

Contact option doesn't work! Can you please add gram to the Cooking?

easy to use

i love this one, and decided to buy it. thank you if i can request it, I hope you can do something like a floating window.

Fantastic all-in-one utility! It replaces half a dozen standalone apps on my phone. Very smooth, highly accurate, and the recent bug fixes make it run flawlessly. Great job by the developers!

fantastic

I really love the app. Especially all the converting options and clean UI. But can you add option to play with the buttons size and positions? Because I want to reorder the dot and delete buttons for example. And the size is too big for me. For some users it might be easier to see but for me it takes up too much space and also requires bigger finger movement.

not bad its a calc what do you expect (calc is short for calculator)

One of the best apps I have ever seen
