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.
