Hi, I'm the maker of KTX Ticket Hunter, a paid Windows app for people planning KTX train journeys in South Korea. Choose a route, date, time range and passenger count, then start checking for seats on your own PC. PRO can attempt reservations, and you complete payment directly with Korail. Your PC needs to stay on and connected. The 64-second video shows the settings and three live checks. None found an available seat. Auto-reservation was off, no reservation or payment was made, and the waiting sections are shortened. Personal information is masked. This is an independent product, not an official Korail app, and it cannot guarantee tickets. PRO costs KRW 4,950 for 30 days, for one person on one PC. I'd welcome feedback on the setup and how clearly the app shows its progress. Demo:
