It's an interesting concept, but it's not an actual cryptocurrency just yet. More of a point based system. They are hoping to make it a crypto. We'll see.
The thing about this app that kinda fucks someone with my fitness routine is that it's only based on walking outdoors. So I can lift weights for an hour and run 4 miles on the treadmill at home and it won't do anything.
I think they should expand their measurements of fitness beyond going for a walk.
...but I'll download it and add you and see how it goes.
