Apple acquired this (it seems last year, but not too many seem to know!). I think this takes maps technology much ahead. We get real 3D version of the streets and buildings and one can zoom up close. It looks much better than the street view on google maps.

They do have both iOS and android versions. But look at the part when it wouldn’t start on Galaxy Tab. bummer… 🙂
