Really, its about 3.5 stars

Basic map that is quite useful for offline reference in Paris. I have an iPhone 4S with retinal display and the resolution detail of the app itself could be much better than it is. The Guide Function is almost useless because the information is, inexplicably, not in alphabetical order. But, overall, if youre going to be in Paris with an iPhone and dont want to pay massive roaming charges for a live map, then getting this app is a no-brainer.
