CPR Coach

CPR Coach is a training-only companion for iPhone and Apple Watch. The Watch uses wrist motion to estimate compression rhythm during practice and sends live coaching information to the iPhone. During a training session: • Follow a simple audible and visual metronome • View compression rate against a 100–120/min coaching zone • Monitor compression count, elapsed time and chest compression fraction (CCF) • Receive a calm pause reminder after movement stops • Use a two-minute rhythm-review prompt for Adult and Paediatric profiles • Select Adult, Paediatric or Neonatal training profiles CPR Coach Premium adds: • Local session history and shareable summaries • Instructor-controlled timing and cadence • Timing-only ventilation cues • Scheduled rhythm-review gaps and an optional defibrillation safety prompt • Graphite and high-contrast interface options Training use only. CPR Coach is not a medical device and must not be used to guide care in an emergency. Motion-derived depth is an unvalidated relative trend, not a measured compression depth. Ventilation is timed only and is not sensed or assessed. Session data remains on the device by default; no account, HealthKit, analytics or cloud sync is used.
