I just noticed that Actifit is now available for iOS. As a computer programmer who is constantly trying to find ways to nerdify my exercise and keep up my motivation for exercise I am intrigued by the concept. I think I will give it a try and see how it all works. The interface looks a little too technical for most users, but I guess if you've figured out how to create a Steemit account one should be able to figure out their interface. I also have a fear about spamming my followers, but we shall see how it goes. I've got a whole idea in my head how Steemit could be vastly improved by filters, but that is a matter for another post.
