Sleep Island: Tracker & Sounds

Bedtime podcasts at your fingertips · Light ambient mode · Start tracking with one tap from your Home Screen widget

Tonight, let sound guide you to sleep.

Sleep Island is an all-in-one sleep app combining rich sleep audio, auto-stop on sleep detection, wearable-free sleep tracking, and snore/sleep talk recording.

No smartwatch needed. Just sleep as usual: the app automatically detects sleep onset, deep sleep, and naps in the background, generating sleep records and trend analysis. It also captures snoring and sleep talking for playback.

Choose from white noise, nature sounds, ASMR, or sleep music. With smart timing, audio gradually fades and stops after you fall asleep. Supports looping, offline, and background playback.

Better sleep through science.
