Why TimeUp Lock
A simpler way to avoid screen-time arguments
Children often ask for "just five more minutes." TimeUp Lock helps avoid those difficult conversations by automatically locking the phone when the agreed time ends.
Without TimeUp Lock
- Parents must keep reminding children that time is almost up.
- The agreed time can easily stretch longer than expected.
- Handing over a phone can end with frustration and repeated back-and-forth.
- There is no simple automatic handoff moment.
With TimeUp Lock
- Set a timer before handing over the phone.
- The timer continues running in the background.
- The screen locks automatically when time expires.
- The parent unlocks the device using normal authentication.
