Must have for Paris
Great app - we used it constantly during a recent visit to Paris. We had used the equivalent app for London, so we simply loaded the Paris map on the iPad. Also used Pocket Earth with detailed Paris maps and wiki info. Works great even without data access. Only time we disagreed with the recommended route was when it selected RER lines (with longer delays between train departures) and we instead manually figured out a M line routing. This issue was not worth taking a star off.
