Sleep Analytics: Sleep Tracker

Understand your nights: sleep score, deep and REM stages, overnight HRV and resting heart rate, sleep debt and trends. Private, on-device. 7 days free.

Sleep Analytics is the sleep tracker that explains your nights instead of just recording them. It reads the sleep your Apple Watch or iPhone already tracks and turns it into stages, recovery signals and long-term trends — privately, on your device.

NOTHING TO START, NOTHING TO WEAR EXTRA No manual bedtime logging and no second tracker. Sleep Analytics reads sleep from Apple Health and analyzes it automatically every morning.

WHAT YOU GET • A nightly sleep score built from duration, continuity and timing • Sleep stages: deep, core, REM and awake, with a clear hypnogram • Resting heart rate and HRV overnight, the two best recovery signals you have • Sleep debt, consistency and how your bedtime drifts across the week • Naps counted properly alongside your main sleep • Weekly, monthly and yearly trends that show the real pattern • Export your full sleep history to CSV or JSON

WHY IT MATTERS Sleep is where training adapts and stress resolves. Seeing that your HRV drops the night after late meals, or that your score collapses when bedtime slips past midnight, is what turns data into a decision.

FOR EVERYONE WHO WANTS ANSWERS Athletes tracking recovery, shift workers fighting an irregular schedule, light sleepers looking for a pattern, and anyone who simply wants to know whether last night was actually good.

PRIVATE BY DESIGN Everything is analyzed on your iPhone. No account, no cloud, no ads, no data brokers. Delete the app and the data is gone.

PREMIUM Sleep Analytics Premium unlocks the full experience with monthly and annual plans, starting with a free trial. Cancel anytime in your App Store settings.
