ZzzSweet is a scheduled screen lock app that enforces device lock at your set sleep time and sends the unlock password to someone you trust, helping you build healthy sleep habits.
A simple and effective sleep management solution
Set your sleep time and your device locks automatically. Supports overnight periods like 11:00 PM - 7:00 AM.
A new 6-digit unlock password is generated daily and sent to your trusted person's email, preventing self-unlock.
Designate a trusted friend or family member to receive the password and become your sleep accountability partner.
The lock screen displays inspirational quotes, gently reminding you to put down your phone and rest well.
When the set end time arrives, your device unlocks automatically without affecting normal use.
Sign in to sync your settings to the cloud and continue using on a new device.
Start your healthy sleep journey in three steps
Register with your email and set up your trusted email (your accountability partner's email)

Screen locks automatically at the set time, password is sent to your accountability partner, sleep peacefully
