HeartMirror

HeartMirror shows your live heart rate and zone on your iPhone, from any Bluetooth strap, armband or Apple Watch. • Live zones: five zones based on your resting and max heart rate, with time spent in each. • Lock Screen and Dynamic Island: keep your heart rate in view in other apps, and log intervals without unlocking. • Guided programs: 4×4, Zone 2 or your own. Steps advance automatically, and your phone buzzes if you leave the target zone. • Recovery: how much your heart rate drops in the minute after you stop. • Apple Health: workouts are saved with heart rate and calories. • History: every workout, plus a weekly breakdown by zone. No account, no ads, no tracking. Your data stays on your iPhone and in Apple Health. HeartMirror is not a medical device.
