About this app
Scientific calculator that simulates an HP-15C. It simulates the appearance and behavior of the original, including the seven-segment display, and the little blink you get when entering numbers. Includes complex math, matrices, numerical integration, solving for the root of an equation and statistics. Very state of the art for 1982!

Haptic feedback does not work. Please fix this issue so it vibrates loudly during each key press.

Google's Flutter defaults to not providing haptic feedback. Be sure you've turned it on in the settings, and that you haven't denied the haptic feedback permission.

Have been using this app for a week now. I love it ❤️. Always wanted a 15C but could not afford it. Now I have it on my phone 😎. Thank you developer(s).

Love it! I still have my HP-11c and use it all the time, except when I am not at my desk. I am so familiar with its layout, and so accustomed to thinking in RPN, that I find algebraic calculators confusing and other RPN calculators inferior. So great to have this authentic substitute with me everywhere! A great gift of a free calculator that does not track me. Thank you, devs, for posting your hobby project.
