Fitbit releases Charge 2 and Flex 2 fitness trackers

Fitbit recently unveiled the Charge 2, a fitness tracker meant to replace the nearly two year old Charge. Unlike the original, the Charge 2 includes a heart rate monitor as standard so there is no standalone HR variant. Fitbit has addressed many other criticisms of the first model in developing the Charge 2. Some new additions include a larger display capable of displaying notifications, a connected GPS feature that uses the phones location for more precise tracking, guided breathing exercises, logging of activities such as weightlifting and biking, auto sleep tracking as well as auto recognition of select activities. The Charge 2 also features interchangeable bands and customizable clock faces.

Also announced was the Flex 2, a small modular fitness tracker that can be worn in different accessories such as bangles and pendants. The Flex 2 offers much of the same functionality of the Charge 2, except it lacks a display, does not monitor heart rate, and is waterproof, enabling it to track swimming exercises.

Both devices interface with the Fitbit App to show comprehensive workout data but operate autonomously to track activities. The Charge 2 can be pre-ordered for $150, and the Flex 2 for $100, from Fitbit.
