    Best iPad calculator ever!!!!!!!!!!!
  • Ads ruin experience - even after PAID FOR UPGRADE

    By LewisFilm
    I wanted a regular old calculator with no ads. I used the free version, and it was constantly interrupted by ads. I paid for the upgrade - STILL has pop up ads. And I’ve seen multiple reviews say the same thing. I am a very generous reviewer, this may be the first 1 star review I’ve ever given. But a simple calculator that you can’t concentrate while using because of pop up ads defeats the point and ruins your work.

    I have used the free version for about two years and now I’ve purchased the premium version. I think that, for me at least, the few bucks was worth the cost to rid the app from the few advertisements.
  • Pop up ads?!?!

    By Joshua8598
    Pop up notification ads for other apps on an app I’ve bought and paid for?! Really?! I’m deleting this app and never using it again.
  • Slow

    By sandogsurfer
    This app is slow to respond. Even after I upgraded from an iPad mini 3 to iPad 2017 I still notice significant lag.
  • 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.

    Numbers are large, and it is intuitive to use. Great to have it whenever I need it while on IPad.
  • Optimized for Multitasking

    By Dutchster
    I upgraded to this version because of the “Optimized for Multitasking” feature. I cannot, for the life of me, figure out how to get this feature to work, or even come up. There is no instructions anywhere, even on their support web page.
