Tripwolf lets you access free travel guides for over 50,000 cities around the world. The guides combine information from professional travel guide publishers and feedback from actual travelers. You can have up to three city guides on your device at one time, and the guides for major cities have a considerable amount of information. However, less visited destinations like Kansas City, Missouri or Des Moines, Iowa, only have a basic information page and a listing of accommodations. You can access the guides online or download them for offline access later.
