## What is RailNetwork?

Getting around Seoul and Korea, made easy — see where your train actually is, in real time.
Whether you're riding the subway from your hotel, taking airport rail from Incheon, or catching a KTX to Busan, RailNetwork shows every running train live, in English.

■ From Incheon or Gimpo Airport
· Search a route from the airport station to your hotel's station
· See the Airport Railroad (AREX) trains and your transfers, with live delays
· Pick your train and get an alert before your stop

■ Live trains on the map
· Subway and KORAIL trains move along the real tracks
· Line diagrams show each train between stations with its delay
· KORAIL trains use GPS positions for extra accuracy

■ Never miss your stop
· Pick the train you boarded and follow the remaining stops on the Dynamic Island and Lock Screen
· Get alerted one stop before and on arrival
· Works underground — it follows your train's live position, not your phone's GPS

■ Route finder with live guidance
· Routes that account for live delays, with transfers and the best car to board
· Voice and notifications for transfers and your stop

■ Between cities: KTX and SRT
· KTX, SRT, ITX and Mugunghwa trains to Busan and across the country
· Train details with stops, times and delays

■ Station arrivals
· Next trains and expected times at any station
· Express or local, destination and delay at a glance
· Search stations by English name
· Home and Lock Screen widgets for both directions, and a live map and station board on Apple Watch

■ When the signal drops
· Underground or offline, the app keeps showing the last data it received, with the time it was updated, and refreshes the moment you're back online

■ Timetables, train diagrams and trainsets
· Station and line timetables laid out like a printed timetable
· A train diagram of the whole line, and trainset info for rail fans

Lines: Seoul Subway Lines 1–9, Airport Railroad (AREX), Suin-Bundang, Shinbundang, Gyeongui-Jungang, Gyeongchun, GTX-A, Seohae, Incheon Lines 1–2, Uijeongbu, Yongin and Gimpo light rail, Sillim, Ui-Sinseol, and KORAIL trains (KTX, ITX, Saemaeul, Mugunghwa).

### 5/5 — 너무좋아요

*2026-10-30*

일단은 엄청나게 좋고 편성, 연식 실시간 추적 같은것도 있어 좋고 새마을호도 있어서 좋고 실시간보다 살짝 느린것만(?)수정해 주시면 좋은 앱이고, 기차여행갈때 좋아요. 앞으로도 잘 쓸게요

수정 요청: 수인분당선

**Developer response:** 확인 후 개선 할 수 있도록 하겠습니다. 감사합니다.

### 5/5 — 모든 기능은 좋습니다

*2026-10-29*

모든 기능은 좋습니다만 다만 성수역에 대해서는 전광판 위젯에서는 모든 열차가 대기 로만 나오고 출발 도착 표시는 없는 것 같습니다 수정이 가능하실까요?

**Developer response:** 다음 패치에서 적용하도록 하겠습니다. 감사합니다.

### 1/5 — 짜구 앱에 들어가면 업데이트하라고 나옵니다.

*2026-10-07*

아니,왜 업데이트를 하라고 하는 이유가 뭡니까? 앱에들어가면 아무것도 안나오게 막아 놓으면 저는 어떻게 볼수 있을까요? 다시 원래대로 하세요 제발 이러지 맙시다. 계속 그러시면은 그냥 삭제 해버리고 사용 안하겠습니다.

**Developer response:** 최신 버전으로 업데이트 해주시면 이용 가능합니다!

### 4/5 — 새로생긴 추적기능 사용시 볼륨문제

*2026-10-04*

미디어 볼륨이 꼭 네비 안내할때 처럼 계속 줄어들어있어요

**Developer response:** 최근 패치에서 수정 완료 했습니다.

### 4/5 — 정확도가 생각보다

*2026-08-21*

종종 떨어질때가 있네요
실시간 반영이 잘 안되는 경우가 많은 것 같습니다
특히 1, 경의중앙, 수인분당은 개선이 필요해 보이네요

### 1/5 — 지하철편성및,번호가 안나옵니다.

*2026-07-20*

앱을 설치를 했는데,모든지하철 편성과,번호가 다 안나와서 매우 불편 합니다.왜냐하면 지하철이 어느역에 있는지도 모르겠고,몇시에 도착하는지도 잘 알지 못하기 때문입니다.다시 원래대로 하셨으면 좋겠습니다.
이용하는 사람들이 분노와,스트레스를 받고 있는거 아십니까?개발자분께서 잘못을 하셨으면 죄송하다고 말씀을 드리는게 예의가 아닙니까? 다시는 이런 행동을 하지 않으셨으면 좋겠습니다.

### 5/5 — 열차 위치가 이상해요

*2026-07-02*

열차를 누르면 현재 위치에 열차가 표시 되어야 하는데, 엉뚱한 곳에 있어서 불편해요.

### 4/5 — 정말 감사합니다

*2026-06-24*

제가 철덕이라 친구한테 듣고 이 앱을 쓰게 됬는데 이걸로 희귀한 열차를 잡았습니다.
정말 감사합니다
다만 한가지 불편한점이 열차 아이콘이 회색이라서 정보랑 편성을 알수 없어서 수정해주셨으면 합니다

### 5/5 — 발열 문제만 고칠 수 없을까요ㅠㅠ

*2026-05-31*

정말 안 좋은 거 없이 완벽한데, 발열이 있어서 fps를 1로 바꾸고 써도 배터리 소모도 꽤 크고 발열도 심하네요. 이거 하나는 어떻게 못 고칠까요ㅠㅠㅠ

**Developer response:** 현재 사용 중인 장치 정보를 bh@2p31.art로 보내주시면 감사하겠습니다.

### 1/5 — 해당 앱 관리 부실

*2026-02-16*

최근에 해당 앱에 운행 기록이 있는 열차가 운행 기록이 없는 열차라 뜨는 게 문제라서 리뷰를 작성했습니다. 제가 지적한 말에 따르면 해당 앱에서 운행 기록이 있는 열차에 기록이 없는 거라고 오류가 뜨고요,게다가 기록있는 열차에 편성 정보 없음이라고 뜹니다.또 일부 열차(1호선 S 다이아)에 행선지가 구간과 다르게 다른 행선지로 뜹니다. 해당 버그 좀 최대한 빨리 수정해주셨으면 좋겠습니다. 감사합니다.
