why does it have to use the camera, that's a bit weird. why not just a map option that shows the locations of other people's iphones (using that find my iphone thing)
but that's essentially what that is, and they make it intentionally so other people can't see it without permission. I mean it's a decent idea but a bit creepy and then there's the whole security part of it
and why does google have to be involved if it's an iOS device, should be looking to ask apple about it
