Track your exercise, set goals and monitor your sleep schedule with one device
Fitbit's latest health and fitness product, the Flex, is finally shipping following its debut at CES back in January of this year. The Flex makes an important improvement over previous products by including Bluetooth 4.0, which lets the device stay constantly connected to your smart phone without drastically draining its battery. The Bluetooth 4.0 functionality is compatible with "select" devices -- Fitbit calls out the Galaxy S3 and Note 2 -- but in reality should work with any modern phone that has the standard implemented. The Flex also implements NFC, so you can simply tap your phone to it to launch the Fitbit app and read your stats right away.
Just like previous Fitbits, the Flex tracks your activity throughout the day, including your steps, distance traveled, calories burned and now "active minutes" of moderate-intensity cardio as well. Because of its improved battery life, Fitbit notes it is also a great companion for tracking your sleep. The Flex is available directly from Fitbit for $99.95 in either black or "slate" (which is actually more of a turqoise color) at the second source link below.
