JRPN 16c

Programmer's calculator similar to an HP 16c.

Programmer's calculator based on Emmet Gray's WRPN 16c, which simulates
an HP 16c. This is an RPN-based calculator that works in floating point,
and integers expressed in hex, decimal, octal or binary. I modified Emmet's
WRPN (with permission) so that it uses rendered fonts for the keys. This
makes them look nice and crisp on high resolution displays.

I offer this software as-is, with no guarantee of any kind. The source is
available on github. There's also a desktop Java version -- see for both.


Although APK downloads are available below to give you the choice, you should be aware that by installing that way you will not receive update notifications and it's a less secure way to download. We recommend that you install the F-Droid client and use that.
