Companies appeared to be ignoring Microsoft’s platforms in favor of iOS and Android. Thanks to Windows Phone 8.1, that might be about to change. Bluetooth support is greatly improved with the 8.1 update, and Fitbit is the first to take advantage of it with a new mobile syncing app for Windows Phone 8.1. Fitbit’s Windows Phone 8.1 app will be available in the Store today, and just like its iOS and Android counterparts it will automatically sync Fitbit activity wirelessly.
