Fitbit has announced that they now support Bluetooth 4.0 syncing to the Samsung Galaxy S4.
Fitbit mentioned that every new phone that adds Bluetooth 4.0 sync support, requires custom development. While many of the new phones coming out have Bluetooth 4.0 hardware, many of them don’t have the necessary software for third party apps (like ours) to access this hardware.
Fortunately, Google has announced that they will be standardizing support for Bluetooth 4.0 in an upcoming Android OS, hopefully jellybean 4.3.
Apart from a number of Apple devices, Fitbit also supports the S3, Note 2 and Note 10.1 .
