I used to use an app called Alarm Clock Xtreme that had this feature. I preferred it because sometimes when I’m groggy it’s easy to tap “dismiss” instead of “snooze”. The app then had a very large snooze button that was easy to press, and required you to press a volume button to dismiss the alarm.
You can see the app here: https://play.google.com/store/apps/details?id=com.alarmclock.xtreme.free
I would love for this feature to be added to Sleep As Android. Yes, I know there’s a feature to do a math problem, but I’m not so much worried about forcing myself to wake up as I am avoiding an accidental dismissal.
Thanks for the great app!
