About this app

Locks your phone when you fall asleep watching videos — so the battery isn't empty by morning and you never lose your place in a film again.

SleepGuard shows a small red circle on top of whatever you are watching, at an interval you choose. Tap it and playback continues. Don't tap it — because you have fallen asleep — and SleepGuard locks the screen, just like pressing the power button.

Why?

- YouTube & autoplay: Without SleepGuard, one video starts the next, all night long. Your battery drains to empty and your morning alarm can no longer ring. SleepGuard breaks the chain as soon as you stop responding. - Netflix, Prime Video & co.: Fall asleep mid-episode and you wake up not knowing where you dozed off — scrubbing back, sometimes through long ads again and again. SleepGuard locks the screen right where you fell asleep.

Features

- Works on top of any video or streaming app - Adjustable interval and reaction time - Eight button positions - Reliable background timing via the system AlarmManager - 9 interface languages (EN, DE, FR, ES, IT, PT, NL, PL, TR) - No ads, no tracking, no internet permission at all
