Verdict

The Fitbit Charge 2 is a versatile fitness tracker featuring a 1.5-inch monochrome OLED tap-sensitive display and an optical heart rate monitor for continuous PurePulse tracking. It is equipped with a 3-axis accelerometer and an altimeter to monitor steps, distance, calories burned, floors climbed, and sleep stages. Key characteristics include 'Connected GPS' for route mapping via a smartphone, multi-sport modes for specific exercise tracking, and personalized guided breathing sessions based on real-time heart rate. Notable pros include its long 5-day battery life, interchangeable bands for style customization, and automatic exercise recognition through SmartTrack. However, its main drawbacks are the lack of built-in GPS and limited water resistance, making it unsuitable for swimming or showering.
