Fitbit owners can use Bluetooth to sync devices on Android, but only on Samsung's Galaxy S3 or Note 2.
The Bluetooth 4.0 sync function comes via an updated app on the Google Play Store. The new app will sync data from theduring the day, compiling graphs and statistics in real time for users.
At the moment, only the Samsung Galaxy S3 and Note 2 are supported for the Bluetooth sync, although Fitbit said that more devices will come.
The app also adds near-field communication (NFC) functionality in anticipation of the NFC-capable Fitbit Flex, which becomes available in June this year. Flex owners will be able to tap their mobile phone to the Flex to immediately launch the Fitbit app.
