The Ann Arbor Hands-on Museum always wows visitors with its scientific exhibits. The Museum just added a component to its guest interaction with its free app, “AAHOM” for iPhone, iPad and iPod Touch. The app features general info on the Museum including contact information, a map of the Museum and upcoming events. Created by Pearl Crescent, an Ann Arbor-based Internet and mobile software developer, the app will also feature videos offering fun facts and other exhibit info to visitors through the use of QR codes throughout the Museum. The AAHOM app is available at the iTunes store or search “AAHOM” at the app store.
