Masha Allah
make it simple
A lot nicer than the calculator I had before. A bigger pad to operate on. No ads to put up with and no waiting for totals. Glad I found this calculator.
nice and helpful app
very good calculator
good app 👌
fantastic
The Best! 👍
This app is excellent
wah
I will personally recommend this app to everyone, its easy to navigate and the history part is very cool it helps to keep record but I will suggest a feature that makes one write the name on the history part so one can keep track just like a note app and it can equally be edited.
perfect
wonderful and very much worthwhile for all it's offer has to give
great

Good. Thanks 👍
it has ads just remove it calc should not have ads
very good
Incredibly functional and easy to use for most people! Thanks for providing it! For a future update, could there please be a way to change the color choices? I realize that's not necessary for most people, but with my neuro-divergence, being able to adjust it to my aesthetic would make a big difference. It'd be easier to focus on using the calculator instead of being distracted by the appearance. Thanks for considering!
I like it,
Great 👍
Very good, now you can convert units in four different ways at once, experience it
best calculator for Business
has adverts but they dont interfere with your work. good app well put together

Easy to use. I love the option of basic or scientific. The tip calculator is excellent for large groups in how to split the check or even for one person.👍

Easy to use. No complicated extras. From basic to scientific, from conversions to tipping fees, this calculator has it all!
cool
Probably the best calculator app. Has extra handy features like discount/tax rate function.
My 5 Stars are not a big DEAL to what Calculator Pro gives me . This app is really wonderful . I can track my calculations from the arranged history it gives, it's quick at giving the answers, I don't have to wait for loading. Thanks to the programmers 👍👍

Very simple to use.
The best calculator app.
The best calculator around. It does what it says on the tin and more. No ads make it a pleasure to use.
Good App but it should be some for features like square cube so we can use it for our school maths work.
Beautiful app with top notch user experience with no bugging adds

edit/update* I have a suggestion, can we get a GST calculator with add and subtract GST / VAT added to the alternative calculators? that would be very handy indeed 👍 * A great all in one calc, I use it for working out kgs to the hectare and acre for sowing crops*****
very good
Excellent app that works very well ❤️
so nice 🙂
very useful application
Easy to use.
nice one.. go for it
awesomely quick and versatile.
it is useful
Basic
So far, so good. Google calculator stopped automatic calculations, hopefully this one won't.
I like this app it helps me... did you expect me to say more it's just a calculator
I've been using this calculator for years instead of my system one and have always been very happy with it. But the ads are almost a dealbreaker. I would gladly pay for an ad-free version.
best so far
good
good because it was pefecte
I love this one!!
I have to have a calculator because eventually, no matter what you do, you need one?And this one works pretty well , so i'm happy with it. You should earn points for using your apps!
great app!
Fantastic Application 👌🏻🤝
first of all I thank God for getting this an awesome app. secondly the app deserves five stars for their well-done job, guys rush to get it it's better than the rest for sure. thanks a lot!
I switched from Samsung to a pixel and the calculator app is horrible. I got this one and now I have all the Samsung functionality and more and no intrusive ads
Wow! A must-download app ever, smart, beautiful user interface, and everything you need in one. Best calculator I have ever come across! Developers, KEEP UP THE GOOD WORK! 🤩📱✨ #App #Interface #Calculator #Developers #Work
One of the Best Calculator App ever I see with Best & Smooth UI/UX Designs ! But only 2 things which I don't like is, (1) App's Round Icon (2) ads. There are many peoples like me who are Ready to buy subscription if App is like this ! so please provide No ads. Option with 149 / 3 M subscription !! i suggest everyone, you should definitely try this App !!
calculator pro is wonderful it's more advanced than all the others that I've tried or I couldn't even see the little numbers but these are bigger so I do highly recommend it
Best ...can see all the figure entered in a glance while doing many data calculation..so can be rectified easily the mistake..
Excellent calculator app, free, does all kinds of unit conversions, very easy to use, non-invasive ads. Perfect! Thank You!
Well laid out display, comprehensive features and easy to use. The best calculator app for Android that I have used over the last 10 years. Congratulations and thanks.
FINALLY! A calculator app that doesn't make you spend an hour trying to find other functions like inch to metric, Celsius to Fahrenheit or others. simple key press and its all there no wading through endless " moron menus" to get things done! nicely laid out and easy to navigate. WELL DONE 5 STARS!
Nice app. Has various options (math, financial, conversions etc.), large keys and legible layout. It's a great calculator for everyday use.
I am finding this to be very handy with all of the functions available. I'm glad that it includes a metric conversion option. Very nice 👌
Love this app. This is simple and I like that they don't share info with 3rd parties!! This is also very clean and not loaded with ads!
Love this app! It's laid out really nice & does many different calculations and conversions - very handy to have all in one place! Thanks for making a great app - Excellent work!
This one is great, i love it, free, no ads, got a good history and does what it suppose to do. Its a flimsy review, but i guess thats me. 😁🤌
If you could grow enough to remove ads, that would be great! Love the UI and all in one functionality.
I use mainly for tracking value of my portfolio and for that is easily the best one yet. Very easy to use and good graphics.
An absolutely sensational app. I mean like bro just try this app and you'll have a fully hassle-free time solving math problems. This is going to be a one-stop app even for algebra. WOW !!!
This calculator app is indeed quite good for all your needs regarding science, currency, and so forth and so on. My only question is, despite what a calculator is used for, why does it contain internet ads??
I rated this app full 5 stars earlier when it did not have ADS! Now I do understand why ads are necessary in the free apps business BUT YOU SHOULD GIVE THE OPTION TO PURCHASE YOUR APP/PREMIUM FOR ONE TIME PURCHASE!!!
I really love this Calculator I use it for so many things & it would be even better if there was a Black Mode & Dark Mode Theme added & be able to change the color of the text i would seriously love it
Not long downloaded / installed this app, but already has proven itself. By comparison my old calculator could not convert centimetres into inches. So that in itself has made this app a very useful app for me. Also it will do other conversions as well, and it's easy to switch between them all. Really nice and useful app, easy to use, well laid out, would highly recommend it, well done.
Great, simple, practical, easy-to-use calculator that suits all needs. Keeps track of numbers so a mistakenly entered one can be deleted and the correct one can be entered without having to start the calculation over. Can be used to convert units and currency and calculate discounts, tips, loans, and even dates. Big, easy-to-read display. Basic and scientific calculator options. All around, superb! Best calculator app I've ever seen or used. Would donate to creator if I could do so via PayPal.
Really nice so far. Would like to see some theme options (black and blue or at least dark). Actually the screen shot theme looks great. When installed it's grey, white , and orange. Maybe I'm missing the theme setting?More conversation options perhaps. Binary, hex, oct calculator. But really it is already very nice and easy to use, with nice options.
Good calculator app, especially since it has scientific. Generally I do the math in my head or on paper first, but for double checking it is great.
As good as I used to be in math, degree in accounting, this app keeps me on my toes. Just about all daily calculations have to be checked. I use app to balance my checkbook. Were it not for app I would need to hire someone to check my transactions daily.
I really appreciate being able to use a free calculator without pop-up ads. That's a big deal for me. I just now installed it so have only used it a little but it seems to be a very nice, simple calculator. Just what I needed. Hoping to find a way to calculate percentages (?). Otherwise, great app. Very happy. Special thanks to the developers!
It provides what I need 😊 All traces can be seen while calculation. Others disappear the digits we pressed from the left side. Thanks
Great app. Wish I could afford to help but so many need help.Any way the trial way is the way to go. I love this app. When I need it, I need it, you know! Not a lot of ads that I've noticed?? Everyone go out of their way to help out. What a lovely place you and your employees, family and friends will love you for the referral. What I've done is send them a text and wait. BEST OF LUCK
I love this calculator. If I could suggest one thing, it would be to add a temperature converter, or even swap it for the data one. I feel that one would be very useful
I like the app, but can you add the functionality to easily tap results to insert. Instead of copying result and then paste. It's just weird. 😄
The UI has improved - to the point it looks good. The underline indicating the current mode is still a little funky looking and glitchy when sliding around, but that can be ignored. Wish I just didn't have that top bar like it's shown in the screenshots. I haven't encountered ads and I'm thankful, but I seriously hate ads in such an essential app. Reason I'm saying this? I know it will eventually come and I'll uninstall as soon as it does.
Great little calculator, fits on cell phone,simple for my wife, can do scientific ,trig or geometry , it is also my preferred cslculator , enjoyable to use.
This is helping great for my old eyes It has very large number "buttons" and a great color theme too It has a scientific calculator as well
always easy to calculate my figures, erase and correct mistakes. very user friendly calculator!.Meets all my needs!
Great calculator for Seniors. I use the basic format that involves adding, subtracting. etc. The numbers are large. The app has the following features, currency converter, discount calculator, units converter, tip calculations, and date calculations.
Great calculator easy and logical in use. Extra function like converter quick and easy. Always accurate, no silly answers. Just what a calculator should be easy.
The calculator is very good, very clear to read, if you prefer, Deg, you will need to reset Deg, & the arrow button to the left, each time of use. This program is geared for Trig, but does geometry just fine. I have the basic calc in my wife's phone, but touching the arrows, it becomes a scientific calculator for me. It is very good on cell phones too. I installed it on everything that I have. It is very capable & yet easy to use. I enjoy it as my preferred Calculator.
Simple.......gets the job done......perfect....More than I expected.....no cheap frills or ribbons.....EXACTLY what a calculator should do....all I want a calculator to do.......when I found how good this I quit looking.....and I had looked a lot.......Thank you so very, very much
Whole calculated digit or numbers are displayed or seen on the screen unlike other calculator apps where initially added digits or number disappear out of screen after few addition or calculation n need to manually scroll to see those numbers n it's quite annoying. But this calculator holds it very well.
Swapped out my stock calculator for this one... it's been super useful! My only recommendation is that I wish it had customizations for styles and colors within the app as well as the app icon. Overall, still great though!
Great Calculator. Just enough but not overly confusing to use. Love the built-in tip calculator too.
Nice interface. Lots of useful applets. A couple of things I'd like to see... 1) A memory feature to make it easy to do repetitive operations with an intermediate value. 2) The ability to enter US distance such as inches, feet and miles as fractions (eg 3/16 inches). Thanks for sharing your work!
It's a pretty simple and easy to use app... I like the user interface, the colors and the conversation options. Good job 👍
I tried 6 different apps before I stumbled across this little gem. So glad I tried the 7th. This is great, does what it's designed to do, has all the features you'd want and actually functions like it's supposed to!!
Is as stated, easy to use, and has lots of converters. Would be great to save memory items without a date, though great to simply edit without recreating the entire string. Still a great app.
Just downloaded this app so far so good. I'll let you know if I how it turns out, anything has got to be better then my scratch w/ pen & paper. The older you get the brain does what it wants when it wants! It's amazing how many brain farts it has now. How my brain must smell!
I wanted a basic calculator that you could edit your numbers without starting over. I also wanted a calculator with memory. So I could go back and review previously totaled numbers. This one has both! Perfect for my needs!
Love the user interface. Simple colours work great, the font style and size is brilliant, using it is simple with no distractions, does what it says on the tin. Update: Reduced to 3* as 100+10% is showing 100.1. To developer, 10% of left number 100 does not equal 0.1. It equals to 10. Plz check all other calculators who work this correctly. thank you
Simple but great calculator app with lots of other tools. The colour of the interface could be more subtle or easier on eyes. Unlike the pictures of the app here, I have bright orange on AC and = buttons, which are a bit glaring.
I went looking for calculator that could do more but was surprised to find this gem. Please don't ruin it like others with full paged ads or ppl will go looking for something to replace this. At this time I will get my friends to download this too.. its really versatile.
Read the response to my previous review carefully, the developer was not aware enough to indicate that their calculator app is not capable of functioning with a key board in the description. There are much better alternatives to this one. By the way, if you look carefully Google's Play Strore gives almost everyone with ratings 4 or more stars so the stars rating is pretty much meaningless here.
This app takes care of all my need in one place. Conversation, Discounts, Percentage,... Very happy and many thanks for the convenience..
There are many really good calculators available, however, this one is the best of them all. - nice interface - rationally integrated functions - no extras that are not needed - not ADS (behind a firewall).
Absolutely love this calculator... If you don't know how to use it properly then I suggest that you ask someone that does, because it is neat and necessary in all cases dealing with financial problems or purchasing a high dollar item.
Must try as i was bored with that aosp calculator which was not having additional featured like converter and all but it has my search is complete (replaced mi calculator).
It is the best calculator I have had the pleasure to use. All the extra settings are very useful.
I wish it was easier to copy paste equations of previously made calculations instead of having to go to history every single time. An insert result option would make my rating go to 5 stars🥰
It is a nice app but would be even more better if it had the hex code calculation functionality for having less calulators to use and less data space used.
I only downloaded this yesterday when I noticed my other simple calculator app was no longer in my cell. My cell is old & has been doing a lot of strange things lately so I will set up the new one today.) But I can't recall which calc I had, so I chose this one & it works just like my last Simple Calculator & works perfectly for paying bills and balancing my bank account.
Beautiful app, very easy to use. The only disappointment is that in unit converter is missing temperature, speed, and fuel consumption.
One of the best apps on my phone. I love the distance and currency converters. All the features with no ads is a huge bonus
I feel nice about this app but there is not so many features that i found in "All featured Calculator" in premium version section(without any disturbance of ads). It is on sale well i am going to buy it. In comparison, many different features available on that calc app. Both are nice. 😍
Calculator Pro, provides many features I use on a daily basis which are very user friendly, simple and quick. I recommend Calculator Pro!
Was looking for a calculator where you can go back and make corrections without deleting all additions and numbers after. Here it is!! Works great!!
What is with this app that show a download size that's 1/4 the size once it's first opened? Where's the additional 17 to 18 Mb coming from? The design is off-putting, too. I like the options to switch been basic and advanced calculators and the tab with features. What I don't like is the app's color scheme and "smile" underline reminding me of Amazon products.
Mind blowing Calculator. So smooooth, feature loaded. Aesthetic look. I am learning app development and this app is an inspiration for me. And surprisingly didn't saw any ads in this app. 👍 Hats off to the Developer.
Simple, easy to navigate, like the adjustable settings. The Unit Converter and Tip calculator are very useful features and easy to access. I use it daily in my shop.
Calculator Pro is awesome, accurate, easy to manage and quick to help u thru those confusing tasks. I recommend the download to everyone .
I do all the math on this app. I add and I subtract and I multiply and I divide. It's adds subtracts multiplies and divides like soooo good! U rock Calc pro!
The display is easy to read and the app has a ton of functions. I would buy this app. This app does say it collects all your personal data. I haven't found if it sells it to 3rd parties.
Great app, and the FX converter works well again! If possible, a °C/°F temp converter would make the app even better. Thanks!
This calculator is the perfect instrument for me to use to balance my checkbook quickly and efficiently. It is indispensable for me. I am so glad I chose to download it.
Okay except I can't figure out how to put a shortcut on my desktop (Acer Chromebook 311); I don't like using the bar or shelf, whatever it's called, at the bottom of the screen, but it looks like I have no choice :( Other than that, it's fine. Thank you!
Awesome calculator that just gets the job done. Ive tried a few calculator apps and some have bad UI/UX but great features while other lack features. This calculator app have just the right mix. I strongly prefer it over the default calculator on my phone (Samsung) Definitely recommend giving it a try.
Very useful and intuitive app! Just waiting for the latest version to fix some problems (errors in unit/time conversion: months, hours...). And also to have the copy/paste option also in the other features (not only in the general calculator function). I hope it will be soon! :)
You can use the number pad to input numbers, but when you choose enter to calculate, either on your keypad or the app, it doesn't work. Enter only works only if you click the numbers with your mouse on the app itself.
Now that I have been able to explore its features, I really enjoy this calculator. I especially like the little extras of easily converting measurements such as centimeters to inches. I also like the tip calculator which simplifies splitting up the bill as well as figuring the tax and tip.
Very easy and big size number. Corrections step are so easy. Not trouble shouting facing quick faster and not hanging in uses.I will recommend for you for Best results.
Great calculator that's functional and attractive! Some of the buttons are in nontraditional places but I think I could get used to it. Wish you could set a default sales tax too.
So far, a solid and dependable app. No crashes, no complications, it does just what I want it to: calculate things.
Good simple calculator with scientific capabilities. I replaced a different calculator with this one and I'm glad I did. The other was a bit of overkill. I don't think I'll ever need much more than this. Excellent app!
Nice UI, but not great at calculating. This app thinks there are 121.67 months in 1 year. It also doesn't let you copy the calculation results, which is a pretty basic feature for any phone calculator.
This calculator has 5 stars for good reasons. I've never ever had a calculator like this one on a mobile device before. Simple easy to use no data draining adds either. I give it a 10
