I sincerely apologize for any confusion. There is not currently a Go365 app experience for your policy type. You can still use Apple Health to track your steps, you will just need to use the Go365 Medicare Workout Tracker 2019.pdf to track and submit your workouts to Go365!
The other option would be for you to attend your SilverSneakers facility at least 8 times per month. This data is received automatically.
