Overview, Critique and Comparisons

The Fitbit Flex Wireless Activity + Sleep Wristband is part of the growing range of lifestyle, activity and fitness trackers on the market today. The device tracks a users calorie intake, their activity level and sleeping patterns. Combined, it provides the wearer with the insights necessary to allow them to make decisive changes to their overall health and well-being. This fitness tracker is worn on the wrist, it is very light, thin and looks very stylish. It resembles a watch in many ways. It comes with two different sized straps to fit most wrists and is available in either black or slate. Other colors are also available, but are sold separately.

The Fitbit Flex Wireless Activity + Sleep Wristband comes with a user interface which provides feedback on your progress, unlike its closest rival the Jawbone UP24, which needs to be connected to a smart device or computer to retrieve even the most basic information. The Fitbit Flex is also much lighter and slimmer than the UP 24 which looks quite bulky in comparison. Battery life, which averages 5 days, is not as good as in the UP24, which last up to 8 days between charges, but is still acceptable. The Fitbit Flex does not monitor the range of activities that the UP 24 can. In this case the Fitbit Flex is more a pedometer/accelerometer and sleep tracker, rather than an activity tracker, but is still super neat.

The device pairs up with both iPhone or Android phones to allow you to monitor your number of steps, distance travelled, caloric intake, time active during the day and sleep patterns. The Flex provides you with goal notifications and target updates.


To help keep you motivated and obtain your lifestyle goals faster, the Fitbit rewards you with badges whenever you achieve one of your daily or lifetime goals.
