WASHINGTON (AP) -- The World War II Memorial in Washington is getting a free mobile app to help teach visitors about the war, the site's symbolism and the millions of people it honors. The nonprofit Trust for the National Mall is releasing the smartphone app Tuesday. Students from Washington's Alice Deal Middle School will demonstrate it for Honor Flight veterans from Missouri as they visit the memorial. The memorial app includes details about the memorial's construction and architecture, as well as a virtual scavenger hunt about the memorial's content. It also includes firsthand accounts from veterans who served in the war, a timeline of milestones in the war and a database to look up the names of service members who were killed. The app is available for download on iTunes and Google Play.
