Thus is the absolute best calculator of all time. Use this app many times per day. Emulation has been rock solid. Prefer it to the actual calculator. Also like it better than the actual hp prime, ti89, or wolfram alpha on the tablet. For some tricky stuff sometimes use maxima on the tablet. Runs good on my s4 also. Only thing I use more for regular rpn math is my wp-34s. If you don't know what wp-34s is and you like hp calcs do a quick Google. UPDATE also works fine on moto x pure running marshmallow too. UPDATE 10/2017. Does not work on OREO.
Recently upgraded to support Android 5 & 6. Note: This.app does not support ARM code. However, almost everything, especially on the User RPL level is Saturn code. It will support extable, Jazz and the very powerful Emacs library. Too use Deep Reset: Select Actions -> Deep Reset . The app will exit. Go to Settings -> Apps and click Force stop. Reopen the app and the calculator will restart. Avoid Hard Reset. Use Deep Reset instead. It work if you stop the app after it quits.
After upgrading to version 1.2 the app crashes often and I lose all the unsaved data on the screen (also resets the skin and orientation.) Please fix this. This app is too expensive to be crashing like that. I'm using this app on a Galaxy S5. Other than that it's awesome and calculates like my real hp50g. I use it everyday
Needs improvement 'Hard reset' doesn't work. Cannot paste clipboard to stack. The help pages are difficult to navigate: Suggest a swipe gesture opens an alphabet menu.
IF YOU HAVE KITKAT OR HIGHER before you do the unistall/reinstall or do a data clear save everything exported by Save Level 1 somewhere outside Android/os2.emul.go49gp/files/files. It is easiest to grab the os2.etc directory out of the Android directory to someplace with a file manager. After that do your uninstall/reinstall. Click Save level 1 and cancel. Then copy your files back and reload them.
How do I get the menu in the new android os?
