Our App today is called the National Parks Service. Last Earth Day, the federal government released this app to showcase all 420 National Parks in this country. The app has interactive maps, virtual tours, and all the information you need for any National Park. You can get ideas of what to do when you decide to visit any of them from the Grand Canyon to Yosemite to Yellowstone. The app will show you self-guided tours when you get to one of the Parks. It also has audio descriptions of the main features at each Park. You don't need an internet connection when you're there, because you can download the information to access offline. It's a one stop information center for every one. The National Park Service is a free app on iTunes and Android.
