Sleep analysis you can understand
Honest, not sugarcoated
For every night, SleepKit shows whether the values are measured (Apple Watch) or estimated (iPhone). That way you know how reliable your sleep score is.
With and without a watch
Without an Apple Watch, SleepKit uses the microphone and motion sensor of the iPhone on your nightstand. With a watch, sleep stages, heart rate and HRV come straight from Apple Health.
Why sleep matters
Sleep is when your body recovers and your brain processes the day. People who regularly sleep too little often feel tired and unfocused during the day. The CDC recommends at least seven hours of sleep per night for adults.
Your nights. Your data.
SleepKit works without an account and without its own server. Recordings stay on your iPhone.
