Version 8.1.1

(Coming Soon)

I just released the latest update for all BETA users:

  • Added the long-overdue UNDO feature for RPN users! There is also a setting that will restore your previous entry or not. Pressing UNDO twice will REDO.
  • The power button will now display xy for Algebraic users. This is only a visual change.
  • The nth-root button will now display x√y for both input styles.
    • This is only a visual change for algebraic users.
    • This reverses the input order for RPN users (as requested by tons of you all).
  • Maximum history and stack sizes have been increased to 100.
  • I also added a setting that will clear the screen when the app shuts down.
    • Algebraic users have all completed equations saved in their history. This won’t save an equation you didn’t press equals (=) on.
    • RPN users can press UNDO if they want to get their stack back.

A few more details can be found here. As always, you can get early access to this release by joining the BETA links on this page.

Version 8.0.2

I just released an update with minor font size adjustments for very narrow devices in landscape orientations.

This improves landscape orientation for devices like the Pixel 9 Pro XL.

Version 8.0.1

I just released a small update to the Play Store with a minor fix for some devices, who’s arrows weren’t displaying properly. Thanks again to Henry for notifying me and helping me test the fix.

Version 8.0

Hi All,
