The simplest way to manage your child's screen time. Set a timer, hand over the phone, and it locks automatically when time is up. Only a parent with the PIN can unlock it.
Three steps. That's it.
Choose how long your child can use the phone - from 1 minute to 23 hours. Toggle "Mute media sound" if you want videos and games silenced when time is up.
Press "Start Screen Time" and give the phone to your child. The timer runs in the background even if they switch apps.
When time runs out, a full-screen overlay locks the phone. Only a parent with the correct PIN can unlock it or close the app.
When time is up, a system-level overlay covers the entire screen. Your child can't dismiss it, switch apps, or use the phone.
PIN 1 unlocks the phone and lets you set a new timer. PIN 2 closes the app entirely. Default PINs are customizable in settings.
Visual warnings at 10 minutes and 3 minutes remaining, so your child knows time is almost up - no surprises.
Optionally mute all media sound (music, videos, games) when the timer finishes. Ringtone and alarms are not affected.
Timer runs as an Android foreground service with a persistent notification. It keeps ticking even when your child switches apps or locks the screen.
No ads, no tracking, no data collection from children. The only network call is license validation (for PRO users). 100% safe for kids.
Free for short sessions. Upgrade for unlimited duration.
