Night Check – Sleep Reminder

A simple night screen reminder to help you stop late-night phone use.
Night Check detects inactivity during late hours and gently reminds you when it’s time to rest.

When your screen stays on at night without interaction, Night Check shows a calm prompt asking if you’re still awake. With one tap, you can enter Sleep Mode and lock your screen, helping you disconnect and rest.
