Going to the theater is always an event that remains in our memory for a long time. We created a mobile application for buying tickets that helps to diversify this experience and make it extremely enjoyable. We solved two problems: firstly, we immerse the user in the atmosphere of the theater even before he enters the lobby of the building on Tverskoy Boulevard, and secondly, we answer the main questions that the theater visitor faces. To go on your own or to go with your parents? How to choose a good place in the hall and how to find your seat? How to quietly leave the room if necessary? And how to make children interested in theater?
