HeartChart for Everyone 12+

Viewing your heart rate data as scatter plots or line charts is useful for when you want to take a closer look at your heart rate data and see the exact measurements from your smart watch or other heart rate recording device. Because the data is read from Apple HealthKit, any device which stores heart rate data in HealthKit will be compatible with HeartChart, such as Apple Watches, Polar, Garmin devices etc. Add the widget to your Today View to easily keep track of your heart rate during the course of the day.

Make sure you authorize HeartChart to read Apple HealthKit's heart rate data. If you authorize it to also read your date of birth, HeartChart will automatically calculate your heart rate zones and color your heart rate values according to their zone (make sure your date of birth is specified in the Apple Health app).

Your data stays securely on your device. We do not store, upload, sell, or otherwise process your data.
