HeartTrackPro — Real-Time Heart Rate Monitor This app is intended for use in regions where the connected Polar hardware has received regulatory clearance, including the United States, European Union, and Canada. This app is not a medical device. Always consult a qualified physician before making any health or medical decisions.

HeartTrackPro turns your iPhone into a professional heart rate monitoring station. Whether you're a serious athlete chasing peak performance or a fitness enthusiast tracking your training zones, HeartTrackPro gives you the live data, visual feedback, and session history you need — all in one clean, focused app.

Polar H10 & Apple Watch Support

Connect to a Polar H10 chest strap over Bluetooth for clinical-grade accuracy and real-time RR interval data, or use your paired Apple Watch via HealthKit for effortless, cable-free monitoring. Switch between devices in Settings at any time.

Live Heart Rate Display

See your current BPM in large, easy-to-read numerals the moment your device connects. A live connection status badge keeps you informed at a glance, and a sensor battery indicator means you're never caught off guard mid-session.

RR Interval Tracking

For Polar H10 users, HeartTrackPro captures RR interval data (the time between individual heartbeats in milliseconds) alongside BPM — ideal for heart rate variability analysis and deeper physiological insight.

Live Chart with Adjustable Time Window

Watch your heart rate trend unfold in a smooth, real-time line chart. Choose from seven time windows — 1, 5, 10, 20, 30, 45, or 60 minutes — to zoom in on an interval or review the full arc of a long workout. Average BPM, peak BPM, sample count, and a running session timer update live alongside the chart.

5 Training Zones

HeartTrackPro automatically calculates your five training zones based on your maximum heart rate and highlights which zone you're currently in:

• Zone 1 (50–60%) — Warm-up • Zone 2 (60–70%) — Fat Burn • Zone 3 (70–80%) — Aerobic • Zone 4 (80–90%) — Threshold • Zone 5 (90–100%) — Max Effort

Set your max HR by entering your age (using the standard 220 − age formula) or enter a known value manually from a lab or field test.

Pause & Resume Recording

Life happens mid-workout. Pause a session without losing your data, then resume exactly where you left off.

Full Session History

Every completed session is saved locally on your device. Browse past recordings with session date, duration, device type, and a per-session HR zone breakdown so you can track how your training load changes over time.

CSV Export (Pro)

Export any session as a comma-separated values file to share with a coach, import into Excel or Numbers, or feed into your own analysis pipeline.

Simple, Honest Pricing

HeartTrackPro is free to try with up to 5 recorded sessions per device. After that, a single one-time purchase unlocks unlimited recordings, CSV export, and every feature added to the app in the future — no subscription, no renewal, no expiry.

Privacy First

All session data stays on your device. HeartTrackPro does not collect, transmit, or share any personal health information.
