What’s new
Version 6.0 · Updated September 18, 2025
Fixed some bugs associated with setting the significant digits in FIX, SCI and ENG modes that were causing crashes Changed the way Pi modifies the stack to make it more intuitive. Added a mode to show the stack when in landscape mode. Be away that when you are entering a number, x will show as 0. If you are experiencing button lag or don't like not being able to play music in the background, change Click Style to none and this will fix your problems.
