Please include your app version (Settings → About) and, for stop or schedule errors, the stop number (5 digits, printed on the stop pole) and the bus number.
No. The app does not track buses or show real-time arrivals, and it does not give an arrival time for each stop. It shows scheduled values from official published data, with the “timetable as of” date next to them. Traffic, detours, and holiday schedules are not reflected.
That is the headway — how often a bus on that route is scheduled to come. For example, “every 8–12 min · 04:30–23:00” means a bus roughly every 8 to 12 minutes between the first and last bus of the day. Where the source gives no headway, the app shows only the first and last bus times.
Many stops have an official English name. Where there is none, the Korean name is spelled out in Latin letters and marks it “Romanized”, so you know it is a spelling, not a translated name. The Korean name is always shown alongside to match the sign at the stop.
Yes. Location is used only for the Nearby list and the “my location” button on the map. You can find any stop by searching its English name, Korean name, stop number, or a bus number. To turn location on later, allow it for this app in your phone's settings. Your location stays on your device either way.
No. The map of Seoul is stored inside the app, so it works with no SIM card or Wi-Fi. When you show a route on the map, the dotted line joins its stops in order with straight lines — it is approximate and does not follow the roads the bus takes. The app does not show where buses are right now, and it does not plan trips.
