  • Not ready for commercial sales

    By john cheese 1776
    Half of the bottom row of “buttons” is truncated. Awkward to use.

    When I need a calculator out of all the ones I have stored are use this one first. It’s just straightforward and does almost everything I needed to do. Great job
  • Buttons cut off on iPad Pro

    By BigFatLeo
    The bottom row of button is cut off while in landscape mode on iPad Pro. Last update is for iOS 11. Developer seem no longer updating his app.
  • Ads with paid version?

    This is unacceptable.
  • Part of the calculator is cut off on new 2019 iPad 12.9

    By devtest1
    Part of the calculator is cut off in the new iPad Pro 2019 12.9 version. It’s the same with all themes with latest updates. Works fine on my 2017 iPad 12.9 but not the newest iPad 12.9.
  • Great app, until buttonless iPad Pro

    By Airforceteacher
    I’ve used this app from my very first iPad, and have always had it on my front screen. Still do, but with the 2018 iPad Pro, the task bar at the bottom obscures the bottom buttons in most of the skins while in landscape mode. Please adjust the orange and brown skin to fit. Great app otherwise, and love the conversions.

  • Tired of nagging rate me dialogs

    By pdspdspds
    Perfectly fine calculator, but I’m sick of being nagged for ratings.
  • Awful Ads

    By Micah Irwin
    I paid full price for this app and they still pop up ads for other apps. Not professional. At all. Do not recommend this app or company one bit. Update: 2/24/2019 Previously mentioned ads are no longer popping up...I assume. Haven’t used this much, so can’t be sure yet. Opened up the app today and it’s not optimized for the 3rd generation 12.9” iPad Pro. The lowest row of numbers is partly off the bottom of the screen in landscape mode. In portrait mode things don’t line up either.
