Sleep Timer is an app that allows you to fall asleep to your favorite music. It works by starting your music and then setting a countdown timer. When the timer ends, Sleep Timer gradually fades out the music and stops it, allowing you to sleep peacefully and preventing your battery from draining. The app is compatible with various music players, including Google Play Music, TuneIn Radio, Spotify, and YouTube. You can easily set the duration of the timer and create presets for frequently used timers. Additionally, Sleep Timer offers a shake-to-extend feature that allows you to extend the timer without unlocking your phone.
The app also offers a premium version, which is ad-free and includes a beautiful widget for your homescreen. Before purchasing the premium version, you can try it with your favorite music player to ensure compatibility. Sleep Timer may request certain permissions to function properly, such as accessing external storage for custom notification sounds and using the Device Administrator permission for the "Turn screen off" feature. These permissions will only be requested when necessary and will be removed if the feature is disabled or the app is uninstalled. If you're interested in trying out new features before they are officially released, you can join the app's beta forum.
Sleep Timer is developed by Patrick Boos and designed by Nordic Usability.
