I’ve enjoyed using the Simple Alarm Clock on F-droid, importantly for me, it requires you to hold down the shut off button for a couple seconds which helps prevent me from accidentally shutting off my alarm instead of snoozing it. Only downside for this app and possibly others is that they may not function if your device OS updates in the middle of the night.
There was and it was fixed by the looks of it. Guessing these apps have not urgently pulled the fixes in and released an update, so F-droid is urging people not to use the apps until so
