Heart Trace automatically checks your heart rate at regular intervals via your Android Wear smartwatch and syncs heart rate data with Google Fit. You can view your heart rate by the day, hour or minute or as a daily summary.

Android Wear smartwatch with heart rate sensor
This app requires an Android Wear smartwatch with a heart rate sensor. You will also need to connect to your Google Fit account to enable syncing of heart rate readings. Heart rate reading frequency and accuracy can be configured but are ultimately dependant on your Android Wear smartwatch heart rate sensor.

A word from the developer
I'm a single developer who created this app for fun in my spare time because I wanted my Android Wear smart watch to regularly take my heart rate (can't believe this feature still isn't in Google Fit!). I then went on to become a Google Associate Developer (again in my spare time) and further develop the app. This app has no commercial backing and is still maintained in my (limited) spare time so it can take a while for bugs to be squished and features to be developed and released. Thank you for your support and patience, magic09.
