You can also now purchase extra features directly from inside PCalc Lite. Buy them individually, or buy everything.
Includes an Apple Watch app, so you can calculate on your wrist!
Fixed a problem with the alternative icon being reset if the app is quit. Sorry!
Added an option to change the app icon on iOS 10.3 or later (if the icon doesn't change on the home screen, restart your device and that will fix it - iOS bug, sorry!).
Along with the ability to change the icon between the existing blue and orange versions, there are nineteen more icons to choose from including lots of colors and some old designs going way back to 1992. To unlock those icons, we've added an optional tip jar.
Since we've never charged for an update, this is an experiment to see if people feel like dropping some extra coins into the jar as a way of supporting the release of new versions. Even if you don't tip, you'll always have the full functionality available.
Added a new "Hot Pink" tint color for the "Samurai", "Samurai Night", and "Backlight" themes.
Now blink the display if you press Equals and the answer is the same as the previous number shown.
Now the change sign button doesn't finish entering a hex, octal, or binary number, so you can keep editing it.
Now supports pasting of Arabic-Indic numerals.
The "TC" button now correctly deactivates 2nd functions.
Fixed a crash when tapping "Reset to Defaults" in settings.
Fixed a crash if you toggled the RPN setting after tapping "Done" in the Advanced section of the settings.
