More maps are now GPS-enabled which makes this app indispensable for traveling; you can put a pin of your hotel onto the map of the city youre visiting and wander around without getting lost - no cellular service or wifi required, just GPS grid on the map and your GPS-enabled mobile device. Not 5/5 because the current version requires 7 taps before you can enter the label when dropping a pin into a map.
