Heart Lens lets you explore recent patterns and the context behind them, including Heart Load, Movement Load, Recovery Reserve and Sleep Support. Heart Data keeps recorded values, timestamps and availability separate from these derived wellness views.

Browse every complication preview for free and discover nine ready-made faces in the iPhone Watch Face Gallery. Adding a face requires a compatible paired Apple Watch. USEFUL FROM THE START The free app includes six-hour Dashboard, Heart Lens, Heart Data, Watch Today and Heart Flow complication views; Personal Ranges on Everyday; supported factual complication families; graph preview and inspection; Heart Flow Lab comparisons; the offline Rolling Heart Guide; and three ready-made Watch faces. Sandstone and System, Light and Dark appearance are free. GO FURTHER WITH LIFETIME PREMIUM One optional, one-time purchase on iPhone or Apple Watch adds longer ranges, Parchment, Signal and Electric themes, graph and Advanced Lab customization, Body Response and Sleep Focus profiles, expanded Heart Rate complication options, four Signal Orbit complications and six additional ready-made Watch faces. Purchase and Restore Purchases are available on either device, with private paired-device ownership sharing. PRIVATE BY DESIGN Apple Health access is permission-based. Heart rate is the only required Heart Flow input; available age, recovery, movement, workouts, sleep, breathing, oxygen and sleeping wrist-temperature context add detail. Missing optional inputs are reweighted or treated as neutral. Date of Birth is used locally for an age-predicted maximum-heart-rate model and sleep-duration guidance; the actual birth date is excluded from Heart Flow caches and paired messages. Sleeping wrist temperature adds limited context relative to your own history. Health data stays on your devices. Rolling Heart has no account, ads, analytics, tracking or developer server. Only limited data and settings needed for paired features move privately between your iPhone and Apple Watch; the Watch builds its own Heart Flow. Optional comparison with your paired iPhone returns aggregate differences. No Health data is uploaded to the developer automatically, and the app does not write Health data. Rolling Heart is for personal wellness visualization only. It is not intended for diagnosis, treatment, monitoring, regulated medical-device use or emergencies.
