Night Check – Sleep Reminder

About this app

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.

Key Features

• Night-time idle detection
• Gentle reminder when you stop interacting
• Minimal Sleep Mode screen with clock
• Optional screen lock (with permission)
• No account, no tracking, no internet required
• Clean and distraction-free design
