Small wrist fit

The Fitbit Alta FB406BKS is a small-sized activity tracker designed for wrists measuring 5.5 to 6.7 inches in circumference. It provides all-day activity tracking, automatic sleep monitoring and smart notifications in a slim black band.

Easy setup

Charging the device and pairing it with the companion app takes only a few minutes. The touch screen responds to taps and swipes, though users with very dry skin sometimes find the display less sensitive.

Five-day battery

A single charge delivers approximately five days of battery life under normal use. Buyers who need continuous GPS logging or multi-week power reserve should consider a different class of device.
