Amazfit Bip is amazing and affordable watch. The only problem that it doesn't allow you to connect your external HRM to it to get better data during interval training. That app is a clever workaround to desired functionality which uses your phone as a bridge.
How does it work?
1. You download and open the app.
2. Select your Bluetooth HRM in the app window
3. You will receive your heart rate as a push notification every 30 seconds or in case if you reached some definite HR zone.
I tested it only with Samsung Galaxy S7 and Wahoo TICKR, So if it doesn't work with some other configuration you are not lucky. Try to write me an email and if I have time I may try to help you.
