Will the data between Nutracheck and Fitbit be transferred both ways?

Yes. When you link your Fitbit account with Nutracheck, you will be able to sync activity data for calories burned and steps from your Fitbit to your Nutracheck exercise diary. We also send your total daily calorie totals back to your online Fitbit account. This shows as 'Nutracheck Diary'. However please note – any activities you add to your Nutracheck diary will not be sent to your Fitbit account.
