Seoul Subway Map
Read full descriptionHide full description
The entire Seoul metropolitan subway - Seoul, Incheon and Gyeonggi - in two drawings: a clean diagram, and a map drawn to real geography. [ Two maps, not one ] A diagram with the lines straightened, so all 657 station names stay clear of each other, with the Han River and the sea drawn in and KTX and ITX stations marked. And a map that puts every station where it actually is, so you can see which direction you are heading and how far it really is. The app opens on the diagram; switch whenever you like. [ Live arrivals ] See where the train is right now: how many minutes until it reaches you and how many stops away it is, updated continuously. No need to look up at the board on the platform. [ Real timetables ] Not averages, not estimates. Departure times come from the official published timetables, so you see the actual train at the actual minute. [ Fast routes ] Enter where you are and where you are going. You get the fastest route, the departure time, the arrival time and the total journey time. Express trains are marked separately. [ Works underground ] The map, the stations and the timetables live on your phone. No signal, no problem. [ 17 languages ] Korean, English, Chinese, Japanese, Vietnamese, Thai, Russian, Indonesian, Uzbek, Mongolian, Nepali, Khmer, Burmese, Bengali, Sinhala, Kazakh and Tagalog. Station names can be shown in Korean or English.

Verdict
The clearest difference is update cadence: Seoul Subway Map at every 5 days against One 버스's monthly. One 버스's advantage is device support (3 vs 1). On price, ads, in-app purchases and iOS requirement there is nothing between them.
