Terms of Use

Sleep Again iOS App — Last updated March 2, 2026

Not a medical device

Sleep Again is not a medical device. It does not diagnose, treat, cure, or prevent any medical condition. The risk score and predictions are for informational purposes only.

The app reads data from Apple HealthKit and produces a nightly wake-up risk score based on HRV, heart rate, and sleep history. This score is a statistical estimate, not a clinical assessment. It should not be used to make medical decisions. If you have concerns about your sleep or health, consult a qualified medical professional.
