The Muzeum Wojska Polskiego (Polish Army Museum) in Warsaw was founded in 1920 by decree of Józef Piłsudski and first opened to visitors in 1922. Its collections document more than a thousand years of the history of Polish arms and soldiers and comprise over 300,000 items. We created a mobile app for Android and iOS phones that works as an audio guide to the museum. The recordings lead visitors through the exhibition and present the most interesting exhibits, so the museum can be explored at your own pace. The audio guide also includes audio description for blind and partially sighted visitors.
