    No complaints works exactly as expected. It is a bit expensive but totally worth it.

  • Haptic feedback for key presses?

    By QuickTake 100
    How about offering an option for haptic feedback when keys are pressed that mimics the feedback on the original calculator?

  • No rotation in iOS 13.1

    By NapyBlue
    Tried to do a mortgage amortization on the 12C after installing iOS13.1 and the app won’t rotate. There were numerous betas of iOS13 when this problem should have been addressed.
