Fitbit Charge 3

A motivating bracelet with an emphasis on extended measurements of the user's physical activity parameters. In addition to the usual pedometer and calorie counter, the wearable also has a place for a high-precision optical heart rate monitor and an SpO2 sensor to assess the level of blood oxygen saturation. The “head” part of the fitness tracker is assembled in an all-metal case, and Fitbit Charge 3 uses a single-colour OLED matrix with touch input support as a display.

The protective glass Gorilla Glass 3 is “knurled” on top of the display. The body of the model can withstand a pressure of 5 atm, which is equivalent to deep diving at 50 m. The bracelet is equipped with PurePulse technology, which automatically recognizes more than fifteen types of physical activity. Additional features include a sleep monitor, an alarm clock and a special timer for breathing meditation. The tracker's capabilities are revealed to the fullest along with the mobile application for the Fitbit smartphone. On a full charge of the battery, the gadget works without energy supply from the outside for more than a week.
