Heart Plot vs FormSight

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
