up to now I were using the app Alarm clock extreme. But I dislike that it uses very many trackers.
Can someone please point me in the direction of a Foss alarm clock app that has a feature to put puzzles like simple calculations before the deactivation of the alarm?
Okay, so I found this which is an app that donates money to charity if you don’t solve the puzzle on time, I don’t know if that works for you.
