ThumpThump shows you how your heart is doing over the course of the day as well as in the past.

See trends in your max, walking, resting, and exercise heart rates from the data collected in your Health app.

All of your heart data in three easy views!

Easy to use Watch App!
Simply open the app for a quick and easy pulse check. Press the Continuous Sample button to have the heart rate sensor active even when you put your wrist down.

iOS 11 is recommended to get the most of out the app, but heart rate data and max heart rate will still be displayed from the watch sensors if running previous iOS versions.
