Clock

Alarm, clock, timer and stopwatch mode

New in version 2.23

**Fixes**
- Fix alarm display for devices with Android version lower than 12
- Fix alarms created in the past and not enabled
- Fix alarm date picker selecting wrong day
- Reset the default ringtone in alarm settings if it has been deleted

Lots of improvements detailed here: https://github.com/BlackyHawky/Clock/releases/tag/2.23

Note: Due to the reset of "Snooze length" and "Gradually increase volume" settings, please make a new backup after updating the app and delete the old one

Does not use internet permission, and thus is 100% offline.
