GPSMyCity is a travel app that provides article and city guides with offline maps and GPS navigation assistance.  There is no need for a data plan or an Internet connection when using this app while traveling. 

Therefore, users may download these travel articles, offline city maps, and self-guided walking tours from more than 600 cities and explore international cities with having to worry about expensive roaming charges. 

The app also includes an option to turn off the GPS in order to conserve battery life on the users phones.
