Lightweight, ultra-thin display – FitBit used a light and ultra-thin plastic square for the Blaze’s 1.25-inch, 16-color OLED display, and it is surrounded by a stainless steel frame, making it comfortable to wear all day.
Changeable straps – Blaze has an elastomer sports strap, which comes in black, plum, or blue, but you have the option to buy additional leather and metal straps to make the watch go perfectly with any outfit.
Power saving mode – The fitness tracker knows when it is being used, and when idle, it enters this mode and the screen turns black. You can flick your wrist or tap the screen to reactivate the screen.

Main features – FitBit Blaze can monitor and record your steps, calories burned, length of active time, number of stairs you climbed, and resting heart rate. It can help you determine the quality of your sleep by showing how much sleep you got, your restfulness, and the amount of time you were awake. FitStar guides your fitness workouts, and map runs can work with your smartphone’s GPS so you can track your path.
Smart functions – Blaze shows incoming calls, receive texts, display calendar reminders, and manage music playback.
Sports modes – There are dedicated options for cycling, open workouts, running, elliptical, treadmill. The built-in heart rate monitor can track specific exercises.
Finally, Fitbit Blaze boasts a long battery life—certainly longer than its rivals. Most FitBit Blaze reviews you see online will cite the superior battery life (which can last up to five days) as one of the biggest selling points of this product.
