About Gap-trip
Gap-trip is an Android travel app for people deciding which South Korean attraction to visit. It ranks places using current weather, air quality, nearby conditions and official real-time crowd data where available, then shows travel time, the nearest station and facilities around the selected destination.
Why I built this
I built it after repeatedly opening a map, a weather app and crowd pages before short trips around Seoul. The problem was not finding famous places; it was comparing whether those places made sense on that particular day. I wanted those checks in one place without pretending unavailable crowd data existed.
