Just what my wife… and I needed...
Without trying to be condescending towards women (I use it too!) or the visually impaired, when it comes to orientation, a blind man could get quicker from A to B than my wife. Since we installed Orientation on her iPhone she never gets lost anymore, as advertised! As for me, I travel a lot for work and it is the perfect companion to overcome the novelty or the disorienting effect of jet lag when in a new city, and so much less conspicuous than a GPS... The interface is great, highly customisable, but simple of use as it should be expected of an iApp.
