러시아워: 지하철 앉을자리 찾기 is a travel and navigation application designed for iPhone users, focusing on enhancing the commuting experience during rush hours. The app provides real-time information on subway car congestion, helping users identify which car has the best chance of having available seats. By leveraging AI and user-input data, it predicts where seats are likely to become available, allowing users to plan their journeys more effectively.

The application features a "car congestion level" indicator, which informs users of the least crowded cars before boarding. Additionally, it offers detailed insights into the availability of seats at current and upcoming stations, specifically during peak commuting hours. Currently, the service is limited to specific subway lines in the metropolitan area, with options to request additional lines through the app. This makes 러시아워 an essential tool for anyone looking to improve their daily commute.
