Verdict

The Fitbit Charge HR is a sleek, 21mm wide fitness tracker featuring continuous PurePulse optical heart rate monitoring, an integrated OLED display, and a 5-day rechargeable battery. It accurately tracks steps, distance, calories burned, floors climbed, and sleep automatically, while also providing caller ID notifications and silent vibrating alarms. Its primary advantages include 24/7 heart rate tracking without a chest strap, a comfortable textured elastomer band with a secure watch-style buckle, and seamless wireless syncing with a highly rated app. However, it is only water-resistant (not suitable for swimming or showering), lacks built-in GPS, and its heart rate accuracy may decrease during high-intensity workouts.
