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.
We recommend using Cardiogram paired with:
Xiaomi Mi Band 3
Polar OH1, H10, and H7
R1 Blue Sigma Sport
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.
