The state of Fitbit wireless syncing is far from ideal for Android users, but the company's latest step is proof that it's slowly getting better. Today, Fitbit updated its Android app to bring wireless syncing to the Galaxy S 4, which follows a previous update for the Galaxy S III and Galaxy Note II. According to Fitbit's blog, its difficulty in supporting more devices stems from software differences on various Android smartphones, which causes trouble regardless of whether the device includes Bluetooth 4.0. On the upside, just yesterday, the Bluetooth SIG announced that Android will gain support for Bluetooth Smart Ready and Bluetooth Smart devices in the coming months, which Fitbit reckons will solve much of the compatibility issues that it and other device manufacturers have faced. So, if you have a Galaxy S 4, take the opportunity to get syncing your fitness data today -- it won't be long before other Android devices get to join in the fun.
