Fitbit call the Charge 3 "our most advanced tracker ever". Given what they've produced in the past, that is one bold statement!
The Charge 3 uses Fitbit's most advanced heart rate sensors and algorithms, giving you 24/7 heart rate tracking. Talking about matters of the heart, the real-time heart rate zones reveals when you're in Fat Burn, Cardio or Peak zones during your workout.
Many devices take a wild guess where calorie burning is concerned. The Charge 3 promises more accurate information in this area so you can get a better idea of how many calories you're really burning.
This feature tells you how long you're in light, deep and REM sleep so you can get an improved insight on how much quality rest you're actually getting.
SmartTrack automatically records common exercises like running, swimming, and various sports. Meanwhile, with 15 goal-based exercises, including running, cycling, swimming and circuit training, it's easy to set goals and track your progress with real-time stats. For more real-time tracking, connect the Charge 3 with your phone's GPS to track pace and distance during outdoor runs and rides.
With the female health tracking feature, the Charge 3 can be used in conjunction with a Fitbit app to track periods, record symptoms and estimate ovulation and fertility windows.
The design and construction of the Fitbit Charge 3 is as tough as you need it to be during strenuous workouts. It's water resistant up to 50 metres making it ideal for the pool...or the shower you take afterwards!
