Flex is a perfect tracker for fitness motivation. Its LEDs light up like a scoreboard as you get closer to completing your step, calorie or distance goal.
Zip is the most basic Fitbit tracker - a clip that can be easily attached to clothes. It tracks steps, distance traveled, active minutes and calories burned.
Fitbit One tracks all of the major fitness metrics, but also keeps an eye on you while you catch some ZZZs. It also gently wakes you up with its smart alarm.
Fitbit Charge is a more advanced fitness tracker than Fitbit's previous generations - Zip, One and Flex, as it lets you see each and every stat in real time.
Fitbit Charge 2 monitors heart rate automatically and continuously, to accurately track calorie burn and ensure you are working out at the right intensity.
