Fitbit Rolls Out Cortana Integration & Background Sync for Windows Phone
Fitbit has rolled out major update to its Fitbit app for Windows Phone 8.1, letting consumers log their activity and food logging using Cortana. Its compatible with all their health trackers including the just-announced Fitbit Charge™, Fitbit Charge HR™ and Fitbit Surge™ activity trackers.
The last release was pretty basic with sync feature, and stats check. With this update, Fitbit is positioning the app to deliver native experience and their commitment for the ecosystem.

Here is the full set of change log
Cortana: You can speak to Cortana to log the long range of 350,000 foods in the Fitbit database. Good thing they are easy, just say “Fitbit, I ate lasagna for dinner” or “Fitbit, I had a coffee with breakfast.” You can also create alarms using Cortana.
Background Sync and Push Notifications: Users can now experience background syncing and push notifications for Challenges, messages, progress updates and more
Fitbit Challenges: Fitbit Challenges are now availble with the app with a dedicated screen. You can directly compete with up to 10 friends and family to help meet and beat goals in new competitions, including Daily Showdown, Workweek Hustle and Weekend Warrior
MobileTrack: If you forget your Fitbit at home or your Fitbit battery has run out, the app can sync the Motion Data availble on devices like the Lumia 630, 1520, 730 and 830 to take into the account.
New Language Support: Initially available worldwide in English, the Fitbit app for Windows Phone now offers French, German, Italian and Spanish languages
** The update is being rolled out. If you don’t see it yet, launch the Store and force check for updates, and you should have it.
