Compare Seoul outings for the 30, 60, or 90 minutes you actually have.
Gap-trip is a free Android app for choosing a Seoul outing when you have a limited amount of time. It compares supported places using available crowd data, current weather, nearby conditions, and estimated travel time. After choosing a place, you can check the nearest subway station and nearby facilities such as restrooms. Crowd and facility data appear only where source data is available, so the app shows when coverage is missing instead of pretending every place is live.
problem
Maps can show where places are, but they do not answer which outing fits the time and conditions someone has right now. People with a 30-, 60-, or 90-minute gap often compare travel time, weather, crowd information, and nearby facilities across several screens.
solution
Gap-trip puts those signals into one outing comparison and ranks supported places for the chosen time window. It then shows travel time, current conditions, the nearest subway station, and nearby facilities, while marking unavailable source data clearly.
Gap-trip is not a navigation replacement. It starts with the amount of free time and compares supported outings using multiple current-condition signals, while clearly showing when crowd or facility source data is unavailable.
