Is there an iPhone app that shows me the direction way home?
Uh, Google Maps works for me...
There are a number of apps...one I use is called Motion X GPS Drive...there is a free version and there is a paid version...99 cents I think. you can also pay 24 bucks a year to have a voice navigate and tell you where to turn and stuff or if you choose not to, you don't pay for the voice directions. It works well for me
