I was thinking about this for home use too, but it only can pinpoint up to 10 meters.

At least in my house, that would basically be telling me they're in the front half or back half of the house, which I guess would be vaguely useful but not really for locating specific objects.

And if it's not in the house then I'd have to be lucky enough to happen to walk near it at some point, since it relies on your company's (ie your family's) phones.

Actually, you will get better accuracy by triangulating with multiple phones (see this comment by OP https://news.ycombinator.com/item?id=21809488 ) Even though I am not sure if their software supports triangulation, or you will have to do it yourself.
