We just released an iPhone App called Burningman ( http://burningmanapp.co/ ) that gives you free Bitcoins based on the number of steps you walk every calendar month.No ads, no gimmicks, no fees. You walk and get Bitcoins. Details on why we built this Ad and how we plan to support it etc are provided in the FAQs ( http://burningmanapp.co/ ).Hope folks will like it and burn to earn Bitcoins. Any feedback and suggestions are most welcome.
