Google Play Reviews

  1. Dostee Hemin-avatar

    This is truly the best calculator I have come across. As its name implies, it's an all in one calculator, and this is where the app truly shines. Conversions have never been easier and easily accessible. The UI is simplistic and nice, but what I really love is the shear amount of categories and calculations the app offers, all of which is at the palm of your hand. This app is fast, reliable, and very versatile. Highly recommended to everyone.

  2. Timothy Frank-avatar

    highly customizable. Bought this app a few years ago and it was well worth it. They continue to update the app with new features and have made it so that you can easily favorite your most used functions for quick access. You can also customize functions to your liking and those customizations stay for the next time you use it.

  3. Kevin Stringer-avatar

    I really like the app but miss being able to quickly go between categories (maybe an option to pin small icons for the categories to the top instead of the dropdown from the search bar). I'd like to see a week option in the date difference as that would be great for medications. I am still trying to navigate the update but I'm happy to see its still being worked on.

  4. saltykid2017-avatar

    Ads are not intrusive but I wish there was a paid version to get rid of them just the same [[edit, very prompt response from developer, thanks!!]] . otherwise a great app with a lot of tools in one. The interface is very intuitive to find exactly the tool you need quickly and I am vompletely in love with being able to put it on my status bar for quick access

  5. Ruby Stewart-avatar

    I really like this calculator. Initially I purchased it for length conversions, but discovered recently how useful the other calculators can be. Just yesterday, I was able to use the time calculator to calculate what time I was going to reach my destination during a long trip. I also think this calculator will be very useful during shopping as well as for math students.

  6. Emil Blom-avatar

    I absolutely love this app! Even before the redesign it was incredibly functional and easy to use, and with the new design in place, it is even faster and nicer. The style is incredibly uniform and mirrors the simplicity. All in all, a great all-in-one app for calculating and converting. Edit: the search feature is great

  7. Luis Angel GR-avatar

    I don't know about the other unit conversions but the storage one does not work, 1 kilobyte isn't equal to 1000 bytes, should be 1024 bytes. Edit: Thank you so much for answering, I had no ideo of the kibibyte lol, Great app, new design is a bit confusing and I miss having the calculator button on the side for some quick maths.

  8. Robert Yancy-avatar

    Easy to use. As Simple or complex as you need. On the negative side, I wish that it would remember the last tool that you used. That is, when the Calculator was the last tool you'd used when you closed the app, when you open it again it should be still on the calculator. Other than that it's a very very useful application.

  9. Eric Sanchez-avatar

    Helpful and Practical in Many Ways. this app has plenty of things that help me when i need a answer of or get curious, especially with the unit converters. From sizes to energy levels it has a lot that can help you not to mention the other calculations it can do with finance or simple things like geometry. For me it doesn't have that many ads either. The occasional one pops up here and there but nothing to crazy. Really like this app. Update, their layout got cleaner and it is now easier to find

  10. Alexis Lopez-avatar

    Went from 5 stars to 3 because they recently changed the entire UI. Not a fan of it. Dark mode isn't even dark. Instead it's gray. I own a phone with an AMOLED display so that kind of defeats the purpose. EDIT: Pushing it up to 4 stars because they still let you download and install the previous version. Current one needs help though. EDIT: Back to 5 stars. Dark mode is now black instead of gray.

  11. Armindo Alves-avatar

    I love you calculator guys, however this new look really ain't sexy and awesome in my eyes, I hope and believe I'm not the only one, can you guys add a setting to go back to the old view, where I could choose my own theme colour and use it in portrait mode, please add this setting coz the old was way better in my opinion.

  12. Martin Chua-avatar

    This is one of the best all-in-one calculator. However, I recently discovered you couldn't exit easily from calculator mode to the previous app, but pressing the back button will land you in conversion mode first - you need to back again to quit the app. Can this behaviour be user define?

  13. Dan Goble-avatar

    The age calculator doesn't work. Contacted them a few weeks ago they never responded. They did an update 2 days ago and it still wasn't fixed. Edit: Thanks for the suggestion, it worked. Yeah, not real intuitive. Look forward to the fix.

  14. Laura Mayhan-avatar

    The new layout is awesome! Great tool. Why keep your boring old built in calculator when you can have every calculator you'd ever need in one place. I used to Google these things every time, now I just use my all in one calculator. Works exactly like you'd expect

  15. Patrick Radoll-avatar

    This has been my favorite calculator for a very long time, helps out tremendously with school work and daily use. The only problem I really have is the mathematical error of saying that a number divided by 0 is infinity and not undefined as is mathemically correct.

  16. Dennis Gehl-avatar

    A friend of mine showed me this app one day, and I've since been using it exclusively for all of my calculations, be it length, weight, currencies, etc. It's a fantastic piece of software to help you out with almost everything related to math. Been using it for years and it's absolutely worth the money to remove ads.

  17. bardok obama-avatar

    I really liked the iconography of small measuring units like of nanometre, or a mile ,gallons These small icons made it look more detailed. I know you people sacrificed it for material design And the new shortcuts that appear on top of the screen are very plane and simple looking you can make them look really good with good icons I wish you could also use some acrylic effects in the app

  18. Mark SKC-avatar

    Great app. I used the free version for years until I finally purchased the paid version. Very useful and the ads of the free version aren't intrusive in the slightest bit like you see on a lot of apps in the playstore. Definitely a great install.

  19. Cardamomum Viridis-avatar

    Cardamomum Viridis


    I did this 44,185.94 + 95,795.52 and the result was 139,981.5. Why??? Did I ask the app to round it off for me to one decimal place? No!! I checked the settings, it clearly stated 2 decimal places. This is very disappointing. I need accuracy and precision and these figures I'm calculating are prices (for my company).

  20. Jenny Black-avatar

    Can you add tabs back in or at least an option for it? I understand why you did what you did but it is annoying to have to scroll through everything just to find what i want if i do not have it favorited even if i know what i am looking for. I know that is what the search bar is for but the option to open a messurements tab would be nice instead of having to scroll through everything to see find it. Other than that not bad at all.

  21. Spider Wings-avatar

    It's great and has a lot of functions but consider adding a different button for launching a basic and a scientific calculator, since it can take a lot of time to go to settings and change it if you want to switch between scientific and regular calculator

  22. Arafat Rakib-avatar

    The new design does not look good. The old design looked much better and the navigation was much more better. Separate tabs for separate categories was better than long list. Thanks for the reply. 😊 Does the new app have anything new other than design changes?. I am changing my rating to 5. ☺

  23. Dalit Michael-Sipper-avatar

    Dalit Michael-Sipper


    Two years ago I gave it straight 5*! It was just PERFECT the way it was. Friendly and intuitive. I used it quite often. A week ago they changed it...😔 Why change a perfect app into a much less friendly and esthetic version???

  24. Hans Schwarz-avatar

    Great set of calculators, smooth design, but I have trouble switching language, is this even option?.. The only thing I miss here is to see the actual formula for each calculation. Edit: developers answered almost immediately, 5 stars now.

  25. Barbara Wiseman-avatar

    Barbara Wiseman


    The previous version I rated 5 stars and commented. Easy to use, have not found a conversion it cannot do. The new version is not good I put it in ounces and cannot easily find grams for example. Will find a better app. Why do apps have to be 'improved' and get worse.

  26. Jack Egan-avatar

    I really like this app and have used it for a long time. But this latest UI update is a big change all of a sudden. I would like it if you could choose the old layout, which I found more coherent and easy to use. Thanks

  27. TheFlyingEpergne-avatar



    Why did you change it? It used to be fine, you could long press the app to show your "favourites" and now you can't anymore. No point favouriting functions. Was such a good app before the most recent update, please add this functionality back. Edit: really appreciate feedback from the dev, just a shame things I personally loved didn't get featured in the latest update but you can't please everyone I suppose!

  28. Biswadeb Pramanik-avatar

    Biswadeb Pramanik


    Appropriate name. Everything that can be expected from a calculator can be found in this app. Using this calculator for more than a year and I like it more after material design 2.0 update.

  29. Kyle Starr-avatar

    The new user interface update made the usability of this app horrendous. I'm not sure what the developer was thinking by making it way harder to navigate and removing the unit conversions unless you add them back into the lists.

  30. Duper-avatar

    Works well enough but it rounds decimal places when numbers are above 100,000. This is infuriating as i use it for school and didn't realize it did this. PLEASE fix this so it never gets rid of the decimal places.

  31. Peter Lyons-avatar

    Recent update has changed the layout considerably and at least one of the calculators I use regularly - Date Difference - is not displaying a result. Needs work since the update and not sure I can trust it now.

  32. lance cummings-avatar

    It has alot of features and it's easy to use however when all I really needed was for tax purposes so it made it complicated for that over all it was handy to have like the average.

  33. Reza Mashayekh-avatar

    A very calculated and accurate program. On the other hand, this program is not just a calculator! It has made all the daily calculations easy for us.

  34. Orion Yazdgard-avatar

    Great app that has a smooth interface and allows for quick access to the calculator mode as well as many other helpful categories. Happy to support to and get rid the ads!

  35. Alex Shamonin-avatar

    The absolute best calculator app you will ever find, although it does feature some small banner ads. Not intrusive but they do exist. Overall: 5/5 stars!

  36. Muhammad Aizuddin Muaz-avatar

    Muhammad Aizuddin Muaz


    Holy! A new major UI update! It looks beautifully modern. Absolute delight to use the app—themes both light and dark, fluid animation, useful calculators etc. This is arguably the gold standard of calculator app in Play Store.

  37. scooter800m-avatar

    Absolutely what I want, it does all the conversions I could ever need or want. Ads are nicely tucked out of the way of the user and are not bothersome at all.




    Recently new updates are bad as I expected. Its design. last design are very nice and easy that's was the reason I choose this calculator. But this updates dissatisfied me.

  39. Natasha Ho-avatar

    Want to give a big shout-out to the team. Love the functionalities before. New UI is very pretty! Awesome job!

  40. Jennifer Deering-avatar

    Jennifer Deering


    AWESOME APP!!! Best choice by far for ALL your calculation needs. You MUST TRY this app. SERIOUSLY AMAZING. FYI I'm not being paid nor compensated in anyway this is my honest opinion.

  41. Ali Tanwir-avatar

    Whoa! This new UI/UX update looks awesome! Easy to use and navigate with modern look and feel. Really impressed! :)

  42. Claudia C-avatar

    This new layout is not useful at all, you tried to make it look modern and ended up too complicated, but works well

  43. Mark Donaldson-avatar

    The app is great and had always worked fantastically. Thank you to the devs for clarifying refund timing. I do recommend paying for this app based on all the tools included!

  44. Justina Matsson-avatar

    Justina Matsson


    Great tool! I use this app all day, every day. Currency exchange rate it up to date. There are so many different calculations.

  45. Dylan B-avatar

    Does every calculation I could need plus a ton more. Plus the basic calculator is way easy to access from the start. I keep it front and center on my home screen.

  46. Sajid Saleem-avatar

    Simply amazing. Downloaded it many years ago and the new update has made the app look just sooooo damn good! Keep up the great work and stay safe!

  47. D. Francesco Valls-avatar

    D. Francesco Valls


    I prefer the old aesthetic, but appreciate the broadened conversion selections. I noticed shoe and ring size converters; how about for other apparel? Especially converting between women's and men's sizes.

  48. Ien Castanos-avatar

    Probably due to the recent update, when opening the app it flickers from the conversion screen to the calculator screen (I have calculator mode on default).

  49. Murad M-avatar

    Love the new updated design! The development team is also very quick to respond. One minor suggestion I have is possible addition of a amoled black theme

  50. Andrew Kalioka Kabaghe-avatar

    Andrew Kalioka Kabaghe


    If you doing accounts or financial or engineering studies, this is the right calculater. It is accurate, easy to use. All calculations can be made here.

  51. paul langi-avatar

    This app is might be missing a few items for calculation. But it has most of what I need for my math class 1,000,000% great!

  52. Ian Playpayon-avatar

    Best calculator so far😁 and it comes handy in class if I need it👍 Edit: Can you add a selection of interface, wherein we can choose bettween the new interface or the previous. Thank you!😁

  53. Michael Fettig-avatar

    Find it harder to find specific calculates. The titles under icons are text wrapped and ugly. Miss the old one.

  54. Dimitris Mouzakis-avatar

    Dimitris Mouzakis


    Very nice app. Like the history in the calculator. Very convenient that it has built in converter for various applications

  55. Steve's Spot-avatar

    Fantastic but needs more calculators like a mean, meadian, mode, range, standard deviation and variance.

  56. Michael Bolton-avatar

    It used to be awesome, but then they "updated" it and now it's terrible. Uninstalling now. Nice work, team.

  57. Rubén Muñoz-avatar

    Huge interface change is absolutely perfect, and I prefer it over the older one.

  58. Mohannad Dabi-avatar

    Great app. I use it alot. One note: in the currency converter they need to change the Saudi flag. Either put a proper one or just write KSA or Saudi.

  59. Ewertonnn 4-avatar

    Missing formula of each conversion, I always want to learn when converting but that doesn't mean I will stop using the app and it is kinda boring look for every formula and how to calculate.

  60. Michael Cox-avatar

    Splendid, absolutely perfect application. No ads, no anything just pure perfection.

  61. Adriana Hollenback-avatar

    Adriana Hollenback


    Excellent for quick conversions. Easy to use. Really nice and convenient.

  62. A Google user-avatar

    I did like this app very much but why did some geek have to screw it all up. Now I have to search for a good. I don't even want to give you one 😭 star, but it won't let me do that.

  63. dydev le-avatar

    Easy to use all in one calculator but too many ads on top. Don't wanna see the app but the calculator only.

  64. Kathy Barekman-avatar

    Wonderful app. Can do any and every thing you'd ever want to do. Simple and easy to use!

  65. Chris J-avatar

    App was amazing before they totally revamped the entire interface. Now it's more taps to perform simple tasks.

  66. Frank Huse-avatar

    **newest update... where did the app icon go from the notification drop down list:( ** perfect app for all my calculation needs. can even appear in my drop down notification bar. so useful for business

  67. Adam Cook-avatar

    Used to be 5 star. I hate the new UI and the new update. It's trash now. Revert changes please. Otherwise, I'm finding another calculator app.
