Wearables Moderate evidence

Fitbit Charge

Slim Google tracker for steps, heart rate, and sleep.

Charge is the band people actually finish wearing. Google now owns the checkout; the product is still a simple daily activity and sleep log, not a triathlon computer.

How to use

Wear 24/7. Treat Active Zone Minutes as a habit score, not a VO2 lab.
