Busan Metro Map

The whole Busan metro in one app — lines 1 to 4, the Busan–Gimhae light rail and the Donghae line. Real published timetables for every station and the fastest route between any two, with no internet needed. ■ Timetables for all 149 stations Not just the big interchanges. Every station on all six lines has a timetable, with separate weekday, Saturday and holiday services, and the first and last train of the day to the minute. ■ A timetable per destination, not per direction Trains from the same platform do not all go to the same place. Line 2 at Seomyeon is split into Jangsan, Yangsan and Hopo services, so you look at the trains you can actually take. ■ Fast routes Enter where you are and where you are going. Two routes come back side by side: · Fastest · Fewest transfers Departure, arrival, total time and number of changes, together on one screen, so you can see what the trade is. ■ Two maps, not one A diagram with the lines straightened, and a map that draws every station where it really is. Both are in the app; switch whenever you like. It opens on the diagram, where names never collide and interchanges read at a glance. Switch to the real map to see how the Nakdong River runs and how far Haeundae really is. Pinch to zoom, smoothly. ■ Korail interchanges done properly Bujeon on the Donghae line and Bujeon on Line 1 are separate buildings 360 m apart. This app shows them as two stations and works out the real walk between them: Gyodae 5 min, Bujeon 7 min, BEXCO 8 min, Geoje 4 min. ■ Live journey guidance Pick a route, start the journey, and the app keeps telling you the next station, how many stops are left, and where to change. You will not miss your stop on a line you do not know. ■ Works without internet The map, the stations and the timetables are all stored on your phone. When the signal drops on an underground platform, routing and timetables keep working. ■ 17 languages 한국어, English, 中文, 日本語, Tiếng Việt, ไทย, O'zbekcha, Filipino, Русский, नेपाली, Khmer, Bahasa Indonesia, Монгол, Myanmar, বাংলা, Sinhala, Қазақша. Station names are a separate setting. Read the app in your own language and keep station names in Hangul, so they match the signs on the platform. ■ What is covered 149 stations, 6 lines. Line 1 (Nopo–Dadaepo Beach), Line 2 (Jangsan–Yangsan), Line 3 (Suyeong–Daejeo), Line 4 (Minam–Anpyeong), Busan–Gimhae Light Rail (Sasang–Kaya University), Donghae Line (Bujeon–Taehwagang). From Seomyeon, Busan Station, Nampo, Haeundae, Gwangan, Centum City, Dongnae and Sasang out to Gimhae Airport, Gijang and Taehwagang in Ulsan. ■ Good for · Checking the last train before you miss it · The light rail timetable on the way to Gimhae Airport · A first trip to Haeundae or Gwangalli · Underground platforms with no signal · Showing the map to a visitor who has just arrived ■ No sign-in No account, no name, no phone number. Saved routes and settings stay on your phone and are sent nowhere. The app does not ask for your location. ■ Data sources Built with public data from the Korea National Railway (전국 도시철도 운행정보). Map data © OpenStreetMap contributors, ODbL. Timetables come from the published annual dataset, so they can be a minute or two out after the operator retimes a service. Live train positions are not shown, because Busan Transportation Corporation does not publish them. Free, with ads.

Verdict
The clearest difference is in-app purchases: Busan Metro Map at none against Speedometer's 2. Busan Metro Map also leads on update cadence (every 2 weeks vs every 4 months). Speedometer's advantage is device support (3 vs 1). On price, ads and iOS requirement there is nothing between them.
