Cardiogram: HR Monitoring

Cardiogram is a modern reliable tool that will help accurately monitor and record your heart rate in real-time, to help keep track of your health and performance. Just power on your sensor and start the app, it’s that easy!

No personal data is sent to our servers, no account or login required, all the information is stored directly on your phone and Apple Health app only. The app is integrated with Apple HealthKit to synchronize and record heart-rate data. No location services are used or required.

You can monitor and record your cardiac rhythm in a range of situations: • During the day to detect heart rate anomalies; • During sleep; • During your preferred fitness workouts or cardio exercises; • As a way of measuring stress or anxiety levels by measuring resting heart rate;

Cardiogram is compatible with a range of modern heart rate monitors with Bluetooth 4.0 (Smart or LE) available on the market. The app has been tested using multiple heart sensors, including Polar sensor (Polar OH1, H10, and H7) with excellent and consistent performance results.

The app relies on a medical algorithm to automatically calculate heart rate limits. The app will display a warning signal when the maximum heart rate limit is reached. Every session is recorded and can be viewed later in simple and easy to understand graph charts. Sessions are automatically saved even when the sensor runs out of battery, to prevent data from being lost.
