Hello @Thinkthin5 as the title of your post infers this has nothing to do with a tracker, I've moved your post to the third party section.
Best AnswerI have just started Nutrisystem and have the Numi app to track my food, exercise, etc and Numi shows my Fitbit steps & progress, but Fitbit doesn't show my Numi food, exercise, etc. It would be ideal to have them communicate so I do not have to re-enter everything in Fitbit.
Through a search of nutri system been able to find out what nutri system takes or gives to Fitbit.
My suggestion is to contact Nutri System since they are in control of what the take or send to Fitbit, who has no control of this sync process.
I found that they have a Facebook page and do respond with help.
