It's like two people comparing their BMIs - it doesn't tell a lot. I do see your app being potentially _very_ valuable in being able to tell individuals when their behaviors are or are not in line with vetted guidelines, or _nudge_ (heyo!) them to do healthful things at a rhythm in line with their best days.
I once worked on a payments platform whose viability depended on mass adoption. One of the reasons we failed, I believe, was due to being more focused on feeding data to merchants and banks vs. providing value to the consumers who were the actual ultimate hurdle to adoption.
I say all this because I think we realized even B2B platforms need to have consumer appeal to be successful. I think once we are able to integrate more platform and build and more social hooks, it will be more appealing to users. Love your feedback though - think you have some wonderful points.
