Fitbit is one of the leading fitness trackers available, and is probably one of the most popular of them all. Unfortunately however it doesn’t support Windows Phone as of yet, meaning that Fitbit users haven’t really flocked to Windows Phone.
However recently a Fitbit spokesman simply stated that “Fitbit is developing an application for Windows Phone 8.1.”. Of course with WP 8.1 a lot more APIs and features are open to 3rd party developer’s making it easier to develop for.
Overall good news for WP users and Fitbit fans.
