Google Maps provides free turn by turn navigation in the US but not everywhere across the world and some Chinese developers have been able to modify the Google Maps app to offer turn by turn navigation everywhere around the world. This is a fantastic news for those living outside the US as your Android phone can be a great alternative to a standalone GPS device.
