Heart rate monitoring is a way to track the data of your heart rate in real time. It can be done using Amazfit T-Rex 2 on the Notify app. There are many benefits of heart rate monitoring, including getting alerts when your heart rate is too high or too low, exporting statistics for analysis, and connecting with Google Fit and spreadsheet.
The watch on the Notify app can detect your heart rate in real time and sends alerts when it detects that your heart rate is too high or too low. You can export statistics from the app to analyze them later and you can connect it to Google Fit for other fitness apps to share data with them as well.
