Fitbit Flex 2 (black)
The Fitbit Flex 2 doesn't have all of the bells and whistles of other trackers, but it's finally swim-proof, and it does the basics and it does them well.
Fitbit Charge 2 (plum/silver, small)
If you don't need water resistance and GPS, the Fitbit Charge 2 is the best overall fitness tracker you can buy.
Fitbit Alta (blue, small)
While ultimately a more stylish (but heart-rate free) version of the older Charge HR, the Fitbit Alta is a winning fitness tracker with solid style appeal.
Fitbit Blaze (plum, large)
Fitbit's first real smartwatch gets a lot of things right, including comfort, features and price, but it's not a slam-dunk design for everyone.
Fitbit Surge (black, small)
The only GPS-capable Fitbit will appeal to casual runners, but more serious athletes should look elsewhere.
Fitbit Charge HR (black, large)
Fitbit's Charge HR combines heart rate tracking, sleep tracking and fitness into an affordable, slim band with good battery life. It's a hard combination to beat.
Fitbit Charge (slate, large)
The Fitbit Charge is a fine replacement for the discontinued Fitbit Force, but you're better off waiting for Fitbit's heart-rate-tracking upgrade.
The Fitbit Force leaps to the top of the fitness tracker heap, with a bright screen, comfortable fit, and a bevy of slick features.
Fitbit Flex (black)
A long list of features and a comfortable fit make Fitbit’s new Flex the best fitness tracker you can buy.
Fitbit One (black)
The Fitbit One is a feature-rich pedometer, but the wristband-style Jawbone Up and Fitbit’s own Flex are more convenient and much better deals.
