The theme of this thesis is the development of an application for the National Park with an interactive map. In the theoretical part of the work, the basics of application development, namely pre-production and production, and research of the market of existing applications on this topic was covered. The components of the application, fonts, color palette, and style of the application were discussed. In the practical part, design solutions of the National Park were created and incorporated into the design of the application taking into account the existing design for the park. After the prototype was created in the Figma tool, testing of the application was carried out on a specific group of people who then filled out an accompanying survey to obtain feedback on the functionality of navigation and the readability of the application. The application is based on an interactive map that will display the attractions located in the park. The map also marks plant and animal habitats and basic information about them. Also, locations for rest, picnics, toilets, stands with native homemade products, restaurants, cafes, entrances to the park and ticket sales points are displayed. The map shows the departure points of tourist boats and their schedule. The application contains the history of the park, contact information and basic information necessary for visiting the park.
