Reviews of Free42

  • Square root function not working

    Not sure why, but the square root function doesn’t seem to be working properly now. Was working okay before. Not sure if other functions are also impacted. Used to love this up until this happened

    Developer Response

    I'm guessing you're in BASE mode. Press EXIT repeatedly until there is no menu in the display, that should get you back to normal. If that's not it, please contact me via email. It is a bit difficult to do tech support in review replies.

  • Fantastic App!

    I have always used HP RPN calculators spanning a period of over fifty years and this App is a faultless rendition of the original calculator.

    One really niggling problem is that the screen has rotated 90 degrees to landscape. Trying to get it back to portrate does not work. Any ideas? Any fix coming?

  • Love this calculator

    I’ve been a fan of RPN for over 40 years. This calculator works great. I don’t typically use it for much more than simple calculations but I use it daily. I absolutely love the haptic feedback with key presses. It’s gives great indication when you’ve typed a number.
