Your alarm sets your bedtime.

Tell EepyMode when your alarm goes off and how much sleep you need. It works back to your bedtime (alarm, minus your sleep, minus 15 minutes to fall asleep) and locks the apps that keep you up until the alarm.

How it works

The lock uses Apple's Screen Time. At bedtime your picked apps show a lock screen with the sleep you have left before your alarm; when the alarm goes off they open again. Unlocking early takes a 60-second wait and a typed pledge, and it ends your streak. Each morning, EepyMode shows a receipt for last night.
