Gap-trip

Gap-trip is a free Android outing-planning app for Korea. Choose a 30, 60, or 90 minute window and a travel mode, then compare reachable places using available crowd data, current weather, air quality, and surrounding conditions. After choosing a destination, check estimated travel time, the nearest subway station, and nearby facilities when source data is available. It is a practical decision aid rather than turn-by-turn navigation. Live crowd information appears only for supported places, and the app contains ads.
