What's New

Rounding is now back to the "Nearest or Even" rule by default, by popular demand.
Added a new "Rounding" section to the Advanced settings, which controls the display, as well as the behaviour of the "Round" button.
Added an option to the Apple Watch app to stop it automatically switching back to the number pad.
Fixed a problem with the "Fraction" display mode on 32-bit devices.
