US War Trivia is a free trivia app, developed by Make It So Studios, which focuses entirely on American war questions. These questions span the entire history of the United States and the free version provides easy and medium difficulty questions, while the hard tier can be accessed as an in-app purchase. Rather than relying on the standard multiple choice format, US War Trivia provides Hangman-style slots and a selection of letters for the user to input the answer with. The application also includes a helpful 'hint' function for when a question is too tough.
