The State Hermitage Museum is the greatest representative of world museums attracting thousands of tourists every day. It was critical for it to create a modern mobile application to provide online excursions through exhibit rooms and give interesting information about museum pieces. IntexSoft team developed a mobile application for devices on Android platform. The user observes collections of famous Russian museum Hermitage and accomplishes virtual tour round its halls. The application contains basic information about the museum (history, ticket cost, location map, working hours, help, interactive map with halls descriptions, etc.). Module "Additions store" assists the user to obtain art collections, manage the list of downloaded/purchased addings. The program contains adverticement, exhibitions and museum news. The user shares best masterpieces in social networks or sends per e-mail.
