### 1/5 — 초기화

*2026-04-01*

업뎃이후로 앱을 켜논 상태에서 다른 앱을 하다가 다시 들어가면 설정해놨던 경로가 초기화돼요

### 3/5 — 경로

*2026-01-04*

모란역 에서 삼 양 역을 쳤는데,, 팔 호선 경로가 뜨던데, 운행 종료, 라고 뜨더라구요. 막차시간도 아닌데, 심지어 팔 호선은 이곳이 종점이라서, 반대방향 열차로 안내를 할 텐데, 이 앱만 유독 그러는 것 같네요. 모란역 뿐만이 아니라, 다른 역에서 도 이런 버그들이 조금씩 나타나더라구요. 수정 부탁드립니다.

### 5/5 — 너무 좋아요!

*2024-12-31*

지금까지 썻던 어플중에 가장 깔끔하고 편리해서 좋아요! 
다만 시간표가 가끔안맞는데 그건 정보가 어쩔수없죠!! 
4호선 당고개 >> 불암산으로 바꿔주세요!! 지도에는 당고개인데 열차는 불암산행이라고 써있어요!!
너무 잘쓰고있어요 ㅎㅎㅎ

### 4/5 — 8호선 노선도 변경해주세요.

*2024-08-12*

다 좋은데 8호선 별내연장선이 안떠요.
꼭 고쳐주세요.

### 4/5 — 좋아요

*2023-10-17*

1호선 서울역에서 18시 26분 출발하는 천안행 급행열차가 출발할때 표시되지 않습니다.

### 5/5 — 만든지 얼마 안된 어플치곤 근래 만든 어플이라 좋긴한데

*2023-10-13*

최적의 경로 몇개씩 안내돼고 이건 좋은데 경의중앙선 중 경의선 구간에서 공항철도 환승시 디엠씨 환승 난이도가 심하게 높아서 홍대환승이 유리한데도 후의 경로로 안내되지 않는 문제가 있고 요금 안내 문제도 개선됐으면 합니다~~!

### 4/5 — 마음에 들긴하는데 7호선 오류 고쳐주세요

*2023-07-24*

7호선 실시간 위치가 안뜨네요.. 고쳐주세요. 그리고 경강선하고 서해선은 실시간위치를 업데이트 해주셨으면 좋겠습니다.

### 5/5 — 생각보다 좋네요

*2023-07-03*

이것저것 지하철 어플 하나둘씩 써보고 있는데 좋네요 :)

### 5/5 — Good!

*2023-03-27*

사용하기 편해요
