Undoubtedly it's a beautiful app with really great feature. But I am really not sure if "no web - only mobile/app" is such a brilliant idea. It's not working on this side of the globe at least; but again, this side is never the focus of devs(even those who are in this part of the world or from this part).
I see the number of reviews on Google Play and can't help but think - out of them many are users who installed Path, realized it's a gorgeous app, left a good review and left after remaining alone for sometime and never came back.
Maybe the goal is not only that a persons should have as many friends only as many he actually needs/deservers(150?) but also that path should not be used by more than some number of people path needs/deserves(how many?).
