Fitbit Alta

Fitbit alta colors

Alta is one of the most attractive fitness trackers released by Fitbit. It is sleeker than previous models and is intended to hug a smaller wrist more like jewelry than a gadget. Plus you can swap out bands by removing the tracker. Similar to other fitness trackers you’ll get your typical things like sleep monitoring, activity tracking, silent alarms and it has a solid battery life.

The device comes with a touch OLED display and has a bit of a learning curve. The screen does not respond to swiping action but you will need to tap to access various modes. There are also some SmartWatch like notifications such as incoming calls, text alerts and calendar updates. Workouts are tracked by the built-in SmartTrack feature. You also don’t need to press any buttons for it to know when you are sleeping.
