These metrics came off as a stripped-down version of Fitbit’s Activity Zone Minutes, which debuted on the Fitbit Charge 4. The continuous heart rate sensor not only tracks your BPM the entire workout, but it breaks down how many minutes you spend in heart rate zones, ranging from relaxed to intensive to anaerobic.

Amazfit Band 5: Fitness tracking and featuresĭespite the difficult-to-see display, the Amazfit Band 5 provides a suite of metrics you can check out once you’ve completed an activity in one of its 11 different sport modes. When I took the Amazfit Band 5 outdoors, though, even at full brightness I couldn’t see the screen in direct sunlight, and there’s no always-on option. The complications and fun watch faces I assigned let me see everything I needed with a raise-to-wake motion, too. The size reminded me of the Fitbit Charge 4, while the color touchscreen responded well to my vertical swipes. I also liked the 1.1-inch AMOLED display at first.
