Fitbit now syncs to Galaxy S4, with more Android devices on the way

Fitbit announced Thursday that its fitness-tracking devices now support wireless syncing to the Galaxy S4, following a previous update for the Galaxy SIII and Galaxy Note II.

While Fitbit aims to support more Android devices, the company says that the difficulties stem from software differences on various Android smartphones. Still, the Bluetooth SIG also announced Thursday that Android will gain support for Bluetooth Smart Ready and Bluetooth Smart devices in the coming months -- which could help solve some of Fitbit's problems. Earlier this month, Fitbit announced the sale of its much-hyped Fitbit Flex Wireless Activity + Sleep Wristband, powered by Bluetooth and therefore light enough on power to be worn all day while synced to a smartphone or tablet. The device, unveiled at this year's Consumer Electronics Show in Las Vegas, is priced at $99.95 and available in the US, Canada, Spain, the UK, France, Germany, Australia, New Zealand, and the Middle East.Meanwhile, the Jawbone UP, a $129 rubber bracelet that measures and tracks your activity all day long, has also released an Android app called UP by Jawbone. The UP bracelet is available in North America and several European countries, as well as the Middle East and Australia. The complete list of compatible Android devices for those regions can be found on Jawbone's website. For more on Fitbit's supported devices, visit:
