A fitness app that gives you somewhere to put the effort.
Most tracking apps hand you a number at the end of a run and leave you to care about it on your own. That works for people who already run. It does nothing for the far larger group who would go out if there were a reason to be out today rather than in general.
XFitNest is that reason. The streets around you are a board, everyone near you is playing on it, and the ground you covered this morning is visibly yours until somebody comes and takes it. You are not competing with a chart of yourself.
It is built in India, for phones people actually own, by a very small team that would rather ship one honest feature than five that nearly work.
