To quate one of the user comments from the Tourpal app page on the Apple app store, its Amazing that an app like Tourpal was not on the app store long ago.
Tourpal offers tourists a complete guide, including GPS directions, an interactive map, audio information about each point of intrest and alot more.
The app itself and the tours come in a large amount of languages making the app a favorite for world wide users.
You can download TourPal from the app store page.
