The National Park Service has announced that now your cellphone can help guide you through Yellowstone National Park thanks to a new free app.  The app is available from the Apple App Store.  An Android version is still in the works.

A press release from the park service says that cell service and Wi-Fi are limited in the park, so visitors are encouraged to download the app before they arrive.  The app will provide information about visitor centers, places to stay and eat, shopping and services, self-guided walking tours, and historic places and natural features.  It will also allow users to explore the interactive park map, which includes large font sizes, illustrated trails and services, scenic highlights and multiple zoom levels.
