Nav-In (НавИн) is a free navigation app designed for students and staff of the main campus of the Russian State University of Oil and Gas (ВГУЭС) located at Gogol Street. This utility and tools app provides a map of the building with Wi-Fi-based positioning and doubles as a directory for the university.

With Nav-In, users can easily locate their position within the building, find classrooms, faculties, sports halls, or cafes. It also allows users to search for and view information about faculty members, including their email, photo, schedule, department, etc. Additionally, users can plan routes between two points or from their current location and get information about the classrooms, including which department it belongs to and who works there. The app also offers a convenient timetable integrated with navigation, reference information, and offline viewing option.

However, the app requires an internet connection to function properly.

Overall, Nav-In is a useful app that can help students and staff navigate the campus with ease. The developers are constantly working to improve the app and welcome feedback from users. With its many features and potential for future updates, Nav-In is a must-have for anyone studying or working at ВГУЭС.
