this app....and, unless I must have GPS in a city, it is the only navigational tool I use anymore when traveling.
My most favorite feature is its real time location....wifi connection or not, it tracks your movements as you move, unlike others I have tried where the delay affects your ability to know where you actually are.
I used it in Athens, Greece, a few months ago.....like all old cities, the roads in the center laid out every which away.
For a directionally challenged person like myself, having this app track your every turn is extremely helpful.
The close-second favorite is the ability to drop a colored "bullet" wherever you like, also to create a name for it which pops up when you tap on it.
Family, friends, turns, locations of any kind, etc.....all laid out in front of you.
