For years enthusiasts of the National Parks have brought their park passport book to all the monuments and parks around the nation. My sister was very into her passport for a while and collected stamps at many parks on a drive across the country. Now an iPhone app can work in tandem with your passport book to add even more fun to the preserved outdoors.
The app features information from the passport book. You can also use the app to view park maps, websites and other information on each National Park. When you’re at the park you can use the camera to record photos and video to be stored with the park on your app.
