The Charge 2
The Charge 2 is Fitbit's go-to tracker for more than just casually monitoring steps. It pushes real-time updates like calories burned and your heart rate data directly to your wrist, as well as call, text and calendar alerts (the Charge and Charge HR only offered call notifications). It's a solid way to see everything you need without constantly pulling out your smartphone and checking the Fitbit app for stats.
The black-and-white display is four times bigger than the previous model, but you can't compare it to some of the higher-end, more colorful smartwatches on the market. There's still no touchscreen either. Then again, this option -- not quite a smartwatch -- is a solid $200 cheaper.
The Charge 2 includes built-in auto-tracking so it knows when you're out for a walk, running or doing yoga versus riding a bike or lifting weights. Meanwhile, a new interval workout feature guides you through high-intensity exercises and rest periods -- a solid feature for those interested in circuit training or personalized boot camps.
