Screen Guard Mamoru

Screen Guard Mamoru keeps your Android screen awake and can block accidental touches when you need a stable, uninterrupted display.

Use it while viewing recipes, sheet music, maps, charts, dashboards, reference documents, game screens, or any other app that should remain visible without unwanted taps or swipes.

No ads, no internet access, and no account required. The app works locally on your device without sending screen contents or activity data outside the app.

KEY FEATURES

■ Keep the screen awake
Prevent automatic screen timeout during a session. Screen Guard Mamoru runs only after you explicitly start it.

■ Touch lock for accidental-touch prevention
A dimmed overlay blocks taps and swipes from reaching the app underneath. Return safely through the ongoing notification or the emergency press-and-hold control.

■ Transparent mode for using other apps
On supported devices, keep the screen awake while continuing to use other apps normally. Because Android overlay behavior differs by device and OS version, the app runs a compatibility test before enabling this mode. Unsupported or uncertain environments are not forced into transparent mode.

■ Automatic stop after 30, 60, or 120 minutes
Every session has a time limit. Automatic stopping helps reduce unnecessary battery use, unattended screen time, and display burn-in risk.

■ Ongoing notification and remaining time
See the active mode, scheduled stop time, and remaining time from the app or notification. Tap the notification to return to the app, or stop the session directly.

■ No ads and no internet access
There are no ads, advertising SDKs, analytics SDKs, or account registration. The app does not request internet permission and does not perform its own external network communication.

PLEASE NOTE

- Behavior may vary by device manufacturer, Android version, and power-saving settings.
- The app cannot fully control protected Android system screens, hardware buttons, emergency functions, or every system gesture.
- Keeping a display on for a long time may increase battery use or contribute to display burn-in.
- Transparent mode is available only after the compatibility test succeeds on the current device.

Keep your screen and touches under control—for exactly as long as you need.
