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!

This is so close to the original, physical calculator -- I'm impressed. I like that it has the vertical, or 'portrait' mode, so I don't have to rotate the phone just for a quick calculation.

I really like how it looks, but I keep having problems with missed keystrokes, which doesn't happen with other similar apps.

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

See https://github.com/zathras/jrpn/issues/102
Also, 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.
