Watch out for @actifit.

It is an application that pays people to move (exercise). People are already earning tokens even though it is not a released token yet (going to be a SMT) similar to @steemhunt.

The developer is planning on integrating the app into Fitbit and Samsung fitness devices, the former which has 25M already on the market.

This has huge potential not only within the STEEM community but also outside of it. They just released their IOS version to go with the android.

To me, this separates it from the rest in that it is not an interface to post on steem which appeals to content creators. This is an app that can appeal to anyone who moves. The posting on STEEM is only a verification for people to receive their AFIT tokens (and earn STEEM along with it).
