I will try to explain :-). If you don't already had done some research. Actifit is a activity tracker which track different activities as walking, running and so fort. When you use it you have to describe what you have done (not cheating) to get upvote and tokens regarding to how many step you have. The tokens will in the future (hopefully) be able to convert to steem. I thought it is boring with only a few words, (must be at least 30) therfore I add some pictures when I do some walking, mostly out in the woods/mountain :-) The footer describe what type activity I have done and how many steps (could also be the header, but again boring....) Maybe I was able to explain?
