Understand your day. Leave room for how you feel.

POWR helps you compare recent readings with your own history, rather than treating someone else's numbers as a personal target. The quality and availability of data from Apple Health affect what the app can show.

A score is a summary. Read it alongside your sleep, recent activity, and how you feel. A reassuring number does not rule out illness or injury.

If there is not enough recent information, a reading may be unavailable. Wear your device as intended and check its permissions before treating an empty display as a conclusion about your body.

POWR reads sleep recorded in Apple Health. It does not perform a sleep study or diagnose a sleep disorder.

Review recent sessions and muscle-recovery estimates together. You can log soreness to add context, but an estimate cannot assess a painful joint or decide whether an injury is ready for loading.

Do not use a recovery percentage as clearance to train through symptoms. A qualified clinician or trainer can help you decide what is appropriate.

The Bio tab can bring together cardio fitness, body measurements, State of Mind entries, and mindful minutes when the underlying data is available. These displays answer different questions and should not be treated as diagnoses.

Cycle information is optional. Predictions are estimates, cycles vary, and this feature must not be used for contraception.

Apple Health permissions are yours to grant or revoke. Some heart-related readings remain on-device; your data explains storage, AI consent, and the separate cycle-sync control.

POWR may help you notice an unusual pattern. It cannot tell you the medical cause of that pattern. Bring persistent concerns to your healthcare professional.
