Heart Plot vs Heart Track Pro

IMPORTANT: This app REQUIRES a Polar H10 heart rate sensor. Heart Plot is a specialized tool designed specifically for use with the Polar H10 chest strap to visualize your heart’s rhythm in real-time using advanced Lorenz (Poincaré) plotting. By measuring the precise RR-intervals (the time between two heartbeats), Heart Plot maps your heart's behavior onto an X-Y axis. This visualization reveals the "geometry" of your heart rate, allowing you to see patterns that a simple pulse reading would never show. SEE YOUR HEART RHYTHM IN REAL-TIME - Whether you are a "data geek," a fitness enthusiast, or someone monitoring for heart irregularities, Heart Plot provides a live, growing window into your cardiac health. - Detect Irregularities: Easily spot premature contractions, or skipped beats as they happen. The visual patterns created on the Lorenz plot can help identify specific types of arrhythmia. - Capture Episodes: Perfect for users trying to "catch" an intermittent heart event to share with their healthcare provider. - Fitness & HRV: Monitor your Heart Rate Variability (HRV) visually during rest or training sessions. - Built for Endurance: Heart Plot is optimized for long-term monitoring. Whether it’s a quick check, a fitness session, or a 24-hour to 48-hour continuous measurement, the app handles long data sets with ease. KEY FEATURES: - Live Lorenz Plotting: Watch your heart’s "signature" form as the plot grows with every beat. - Stay-Awake Mode: A dedicated toggle to keep your screen on for constant monitoring during workouts or clinical observation. - High-Resolution Data: Captures every RR-interval directly from the Polar H10. - Data Export: Done with your measurement? Download the raw data as a CSV file (including all RR-intervals and timestamps) via the standard Apple Share Sheet for further analysis in Excel, Python, or R. PRIVACY FIRST Your health data is yours alone. Heart Plot does not store your data on any cloud servers. All measurements remain locally on your iPhone until you choose to export them or take a screenshot. MEDICAL DISCLAIMER: Heart Plot is a data visualization tool and is not intended to diagnose, treat, or prevent any medical condition. Please consult with a medical professional to interpret the data. The patterns revealed in the Lorenz plot are for informational and educational purposes. Requirements: - Polar H10 Heart Rate Sensor (Chest Strap) - Bluetooth-enabled iPhone

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.
