Fitbit Surge ( black, large)
All-day heart-rate tracking is a step in the right direction, but the smart features aren't nearly smart enough and the fitness side of the Surge is too basic to justify the higher price.
Fitbit Charge HR ( black, large)
Fitbit's Charge HR adds heart-rate tracking to an already solid fitness band at a great price, but all the kinks don't feel fully ironed out yet.
Fitbit Charge ( large, black)
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.
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.
The Fitbit Zip is the best fitness tracker you can buy for under $60.
