Your morning resting heart rate is one of the most powerful wellness signals your body gives you each day. Here's how to track it consistently — in 60 seconds.
The variation between heartbeats — your nervous system's report card.
Two metrics, one number. Why Pulse shows both — and which to watch.
Training-impulse: your weekly training load, in one chart.
Take your reading within 3 minutes of waking, while still lying down. This captures your true resting state before posture changes, caffeine, or morning activity affect your heart rate.
Place your fingertip gently over the rear camera. Pulse Rate will illuminate it with the flash and capture a clean signal — even a small fidget can add 3–5 bpm of artifact.
Log notes on sleep quality, alcohol, stress, or a late meal alongside your reading. In 2–3 weeks, clear patterns will emerge showing what affects your resting heart rate.
Resting HR changes slowly but meaningfully. A 5-bpm drop over 30 days of consistent aerobic exercise is a clear indicator your cardiovascular fitness is improving.
The same chart that lives on your iPhone's Progress screen — rebuilt so you know what you're looking at.
Outstanding score. Your key heart metrics are above normal.
Most healthy adults fall within this range.
Not necessarily alarming — but worth monitoring.
If this persists, please consult a healthcare professional.
TRIMP = duration × intensity. A 60-minute easy run scores about 70 TRIMP. A 30-minute interval session scores 110. Pulse adds them up daily and tells you when your week is too light, just right, or about to overcook you.
You've already got the hardware — your iPhone. Pulse does the rest.
