A one-hour gap in Seoul is not a full-day itinerary

An appointment ends early in Seoul and you have 45 minutes. A normal itinerary list is too broad, but opening a map and zooming around still does not tell you what is realistically reachable.

I changed Gap-trip's comparison flow around that problem: choose 30, 60, or 90 minutes and a travel mode, then compare places by estimated travel time, weather, air quality, and official crowd data where public coverage exists. After picking a destination, the route can be opened in KakaoMap or Naver Map, with nearby station, restroom, or nursing-room checks tied to that place.

It is a free Android app with ads. Crowd and facility coverage varies by place, so I still recheck official hours and same-day notices before leaving.

If you had 45 minutes before your next plan in Korea, what would rule a place out first: travel time, weather, crowd level, or facilities?
