ScreenTimer

Screen Timer shows a persistent notification that triggers
a live screen time tracker every time you unlock your phone.

The goal is simple — put your phone down before the number
gets too high. When your screen goes to sleep, the timer resets
and you start fresh.

No scores, no streaks, no social features. Just you and a
number that keeps climbing until you put the phone down.

Features:
- Persistent notification counts up from screen unlock
- Resets to zero every time your screen sleeps
- No setup, no account, no internet connection required

A simple way to monitor phone usage and reduce screen time,
one session at a time.
