Which is Better?
All the three smartwatches will track all the basics like your steps, heart rate, calories, and distance. However, Both Bip and Bip S have inbuilt GPS which Bip U lacks. You’ll need to carry your phone along if you intend to track outdoor activities with the Bip U. The Bip and Bip S also have longer battery life than Bip U, thanks to the reflective LCD display.
On the other hand, the Bip U has more preset sport modes, 60 compared to 4 and 10 of Bip and Bip S respectively. It also features stress management and menstrual cycle tracking. And the larger 1.43 inches TFT colored LCD display with a higher resolution is richer and more colorful than the reflective LCD on Bip and Bip S.
VERDICT: Amazfit Bip S is my preferred choice, I think its a more comprehensive smartwatch with inbuilt GPS and long battery life. While the Bip U looks very interesting, but without inbuilt GPS it defeats the purpose of a true fitness tracker. However, the Amazfit Bip U Pro which is yet to be announced will have an inbuilt GPS.
