Paris 2Go is an app that you can download for you iPod, iTouch or iPad and access offline- no WiFi or Internet is necessary. We reviewed Paris 2Go and wish we had it on our recent trip there! It has detailed maps of the city with street searching capabilities, a full Metro map including which stop to take for each attraction, details on 4,800 points of interest (everything you need to know about the Louvre, Eiffel Tower and much more), and 600 articles about the city’s history, interests and geography. You can find it on iTunes for $0.99.
There are at least 15 other city apps including New York, London, Rome, Chicago, Munich and Prague. Also the City Maps 2Go app has hundreds of maps (over 2,400) that you download and access without further needing WiFi.
