The Lose It! mobile app helps you monitor your activity, nutrition, and other fitness stats. It also allows you to connect your Nike+ FuelBand with your Lose It! account, tracking your NikeFuel, steps, and other FuelBand data along with your other personal data.
Normally, once your FuelBand is linked to your Lose It! account, your data automatically syncs to Lose It! anytime you sync your FuelBand to your Nike+ account. Due to a known issue we're working hard to resolve, some users are experiencing a delay or failure in their FuelBand sync to Lose It!
If you are experiencing this problem, please force a sync by opening the Lose It! app on your mobile device, navigating to More > Apps & Devices > Nike+ FuelBand, and tapping Force Sync.
