Fitbit is one of the more popular choices in the personal fitness tracking space, and today at CES the latest device in the range has been introduced. The Fitbit Flex takes the form of a waterproof wristband. Like the existing devices in the range, it records information such as steps and total distance covered and sends this information to your personal website. The Flex will also keep track of your sleep, but with no buttons to enter sleep mode as on the other devices, you’ll have to use either the mobile apps or the website.
Speaking of the mobile apps, one massive drawback to the current iteration of the Fitbit Android application, is the lack of syncing. All that is set to change beginning from the end of January or early February. It will start to offer Bluetooth 4.0 syncing — initially, only to the Samsung Galaxy S3 and Note 2, with more devices “coming soon.”
