How it works

How Sleep Cycle works

Sleep Cycle uses your smartphone's accelerometer and microphone (or a paired Apple Watch) to detect movement and sounds while you sleep. The app builds a simple hypnogram and identifies light versus deep sleep phases. During the configured alarm window it chooses a moment of light sleep to wake you gently, aiming for a less groggy start to the day. Placement guidance improves accuracy.

Features and compatibility

The free app offers basic sleep tracking and a smart alarm; Premium adds detailed statistics, heart-rate trends (when available), sleep aid sounds, and data export. Sleep Cycle is available for iOS and Android and can share data with Apple Health. Setup is quick: install the app, choose monitoring method, and enable the alarm window to begin nightly tracking.

Privacy, subscriptions & support

Sleep Cycle stores sleep data locally on your device and provides options to back up or export. Premium is a monthly or annual in‑app subscription with a free trial on most platforms; cancellations are handled through the App Store or Google Play. For refund requests or troubleshooting, consult Sleep Cycle's support pages or contact customer service via the app or website.
