Fitbit just reveiled its new Charge 2 and Flex 2 activity-tracking wristbads. The Flex 2 is now the company’s first waterproof tracker and like its predecessor, tracks steps, distance traveled, calories burned, and sleep.
It doesn’t have a display but uses four tiny, color-coded LED lights to tell you how far along you are in your daily step count. It signals when you’ve reached an activity goal, or alerts you to smartphone notifications.
The new tracker comes with a Smart Track feature, which means it automatically recognizes when you’ve started certain exercise activities. However, it doesn’t have optical heart rate sensors, or GPS.
The tracker will also vibrate when you’ve been sedentary for too long.
As far as swimming, it will recognie when you are swimming and is waterproof up to 50 meters.
At a price tag of $99, the expected battery life is around five days. It’s available for preorder but won’t ship until sometime in early October.
