A minimal, privacy-respecting sleep timer for Android. Starts a countdown that stops media playback, fades audio out, and optionally locks the screen when it ends — so you can fall asleep without your phone draining the battery or blaring podcasts at 3 AM. No accounts, no ads, no trackers, no network access. Features:
