Earn a Fitbit with 8 engaged weeks in the Medicare-covered program.
In each engaged week, check in with your digital coach or log a meal or activity, and log at least one weigh-in on your Lark scale.
To receive your Fitbit incentive, you must accumulate 8 engaged weeks in the Lark Medicare Diabetes Prevention Program. A week counts as engaged if, within the same calendar week (Sunday through Saturday), you complete at least one check-in with your digital coach or log at least one meal or activity in your Lark app, and you also log at least one weigh-in using your Lark scale. The eligibility window to receive your Fitbit incentive begins when you complete your first check-in with your digital coach or log your first weigh-in, meal, or activity, and it ends upon the earliest of the following: the end of your service period, Lark's determination that you will no longer be receiving services, or 90 consecutive calendar days without direct contact (including telecommunications) between you and Lark during your service period.
Fitbit is a trademark of Google LLC. Provided by Lark as a program incentive; not a Medicare-covered item.
