Last year Fodor’s made their awesome City Guide apps free. They started with New York City, Paris, London, Rome, Barcelona, and San Francisco. Since then they’ve launched Austin, Las Vegas, Miami, New Orleans, Philadelphia, and Seattle. These city guides offer Fodor’s travel expertise and top recommendations, from sights and shops to restaurants and hotels. They’ve also developed really useful interactive maps that work offline so you can plot and plan even from the subway or on your flight. Within the app, you can make all manner of bookings Over the next couple of months, you can expect to find San Diego, Chicago, Boston, Amsterdam, Montreal, Honolulu, Charleston, and Savannah city guides, as well.
