See your nervous system respond to stillness.
Real-time heart rate biofeedback during meditation. AirPods Pro 3 capture every heartbeat — you watch your body downregulate in real time. No chest strap. No watch. Just breathe.
HRM isn't a meditation app. It's a measurement instrument for people who already have a practice and want objective data on what happens inside.
Daily practice, 1+ years
You sit every day. You've tried Headspace, Calm, Insight Timer — you don't need guided content anymore. What you want is evidence. Does today's session look different from yesterday's? HRM shows you.
Data-driven optimizer
You track sleep, HRV, nutrition, training load. Meditation is the one practice you can't measure — until now. CSV export, session-by-session stats, trend tracking. Your meditation finally has data.

Breathwork is nervous system training — and HR is the first signal that shifts. Watch your heart rate respond to inhale/exhale cycles. Real-time biofeedback for the techniques you already use.
No accounts, no onboarding flows, no tutorials. Open the app. Sit. See what happened inside.
Choose your duration — 5 to 60 minutes. Press begin. A 5-second warm-up lets you settle, then a bell marks the start. Optional interval bells keep you grounded without breaking the state.
AirPods Pro 3 capture your heart rate every 5 seconds. Watch your BPM respond to stillness — or lock the screen and let it run silently in the background. The session continues either way.
Every session saved automatically. BPM chart over time, min/max/avg stats, readings count. Export to CSV for deeper analysis. Track your streak and watch your baseline shift over weeks.
No gradients, no illustrations, no decorative elements. Typography-driven interface that disappears so the practice can begin.

Session detail
Session history
Every feature exists because it makes the practice measurably better. Nothing ornamental.
Clinical-grade optical sensor built into the earbuds you already own. No chest strap, no wrist device. Just wear your AirPods and sit — the app captures every heartbeat, no battery drain, no extra hardware.
Core sensorLock your screen. Put the phone down. HRM keeps running — heart rate capture, timer, and bells all continue. Your practice shouldn't need a screen.
Configurable dings — every 1, 2, 5, or 10 minutes. Each bell paired with haptic tap. Gentle anchoring without breaking the state.
Every session stored locally. BPM chart, duration, readings count, avg/min/max. Swipe to delete. Your practice, documented.
DataExport individual sessions or all at once. Full data — timestamp, BPM, source device. Share with your coach, therapist, or analyze in R/Python.
Consecutive days. Total sessions. Total minutes. Simple accountability without gamification noise.
AirPods Pro 3 include a clinical-grade optical heart rate sensor. No extra purchase. No extra device to charge. The most invisible biometric tool you can wear.
Drains battery in minutes
Continuous heart rate polling kills the battery fast — we tested it, the Watch died within minutes of a session. Plus: bright screen on your wrist, notifications, the temptation to check the time. It measures your heart but pulls you out of meditation.
Uncomfortable
The gold standard for accuracy — but the wrong tool for stillness. Tight band around your ribs. Constant awareness of hardware on your body. The opposite of letting go.

Decades of research connect resting heart rate and heart rate variability to parasympathetic function — the body's ability to downregulate stress.
Meditation training produces measurable reductions in resting heart rate, indicating enhanced vagal tone and parasympathetic dominance.

Real-time biofeedback during contemplative practice significantly increases practitioner engagement and self-reported awareness of physiological states.

Heart rate provides an accessible proxy for sympathovagal balance. Consistent HR reduction during meditation correlates with improved autonomic flexibility over time.

HRM v1 captures heart rate. Future versions will interpret it — turning raw data into actionable insight about your nervous system.
