Outdated: Simple Calculator

Current Version on F-Droid, 1.12: https://f-droid.org/packages/com.simplemobiletools.calculator/

Current Version on GitHub, 2.0: https://github.com/SimpleMobileTools/Simple-Calculator/releases/tag/2.0.0

If there are no barring issues, it would be great to update this app, since the newest version allows color customisation. Thanks!
