This smart watch is equipped with a newly upgraded biological optical tracking sensor, the BioTrackerTM 2, that supports measurement of blood-oxygen saturation6. When feeling unwell, under mental stress, engaged in intensive workouts such as marathons and gym sessions, or in high-altitude and hypoxic environments, you can immediately measure your blood-oxygen saturation and understand your physical state.

The Bip U helps you record your exercise data to help you work out at a higher level. You can check your walking distance, speed, heart rate changes, calories burned, and other key factors such as whether you are exercising in your fat burning zone or cardiopulmonary strengthening zone based on your heart rate, as well as receiving instant alerts when your heart rate gets too high.

Water-resistant up to 50 meters(3), you can wear the Bip U for swimming and it will track your movements and record your achievements even under water.
