Optimity is based on app tracking how much steps you do a day. You have to have an app or compatible hardware to sync it with, like FitBit, Garmin Connect, Google Fir or Samsung Health.
You get points for reaching daily goal (6000 steps as of now) and if you have a buddy and you both reach 10 daily goals within 7 days you both get extra points. No limit for number of buddies.
You can exchange points for different things. Yes, a lot of walking is required and a loooot of points but little by little and you can get something of it. Beside losing extra weight.
So if you use Optimity, send me your Invite code.
