Three tips to track your heart rate effectively:
1. Wear your tracker slightly tighter to make sure the heart rate sensor is always in direct contact with your skin, your tracker should lay flat about one finger’s width away from your wrist bone.
2. The tracker shows the beats per minute (BPM) figure on screen, please wait 10-15 seconds for the reading to stabilize.
3. You can get the post-workout summaries of heart rate on App after synchronization if you use activity modes.
