Audio Player - Sleep Timer
A lightweight player built for the music already on your phone. Made for falling asleep to music, audiobooks, and language practice.
Requires Android 7.0 or later
━━━━━━━━━━━━━━━
🔒 No internet permission
━━━━━━━━━━━━━━━
This app does not request the internet permission, so it cannot upload anything even if it wanted to. No tracking, no data collection, no ads. Playback and file handling happen entirely on your device.
━━━━━━━━━━━━━━━
⏰ Three timer modes
━━━━━━━━━━━━━━━
✔️ By time — counts down and stops on its own
✔️ By play count — stops after N plays, handy for drifting off or drilling a single phrase
✔️ Interval — play X minutes, rest Y minutes, repeat N rounds. Works for Pomodoro, shadowing practice, meditation and interval training
Choose what happens when the timer ends: pause, stop, or close the app.
The time mode also runs in reverse — it can start playback when the countdown ends, so you can settle in first and let the music come in a few minutes later. (It is a countdown, not a clock alarm.)

📝 Synced lyrics and subtitles
━━━━━━━━━━━━━━━
Supports SRT and other synced subtitle formats alongside plain lyric files, with an adjustable time offset to line them up. Useful for singing along, following an audiobook, or studying language material.
