Yeogiya Downloads & RevenueYeogiya - Korea Subway Alert · App Store

Never miss your stop on Korea's subway.

Visiting Korea, or living here and still getting used to the lines? Pick the station you want to get off at, and Yeogiya follows your train stop by stop. It tells you one stop ahead, says "Get off now" when you arrive and shows where to transfer, even while you're watching a video with earphones in.

■ Easy for visitors
• Station names appear in Korean with romanized spelling, so you can match them with station signs and announcements.
• Search stations in English letters, such as "Gangnam" or "Myeongdong".
• Includes the AREX Airport Railroad to Incheon and Gimpo airports.
• The app follows your phone's language: English, Japanese, Chinese, Spanish, French or Korean.

■ Even while you watch videos
• At each station, a Live Activity expands in the Dynamic Island with the station name. On iPhones without the Dynamic Island, a card drops down from the top of the screen.
• The Lock Screen shows the current station, the next station and the stops remaining.
• When it's time to get off, a Time Sensitive notification is sent too, which can come through even with a Focus on.

■ Your stop, one stop ahead
• When the train leaves the station before yours, you're told to get off at the next stop. When you arrive: "Get off now".
• When it's time to get off, alerts and vibration repeat so you don't miss it.
• Turn on voice guidance to hear it as well.

■ Transfers worked out
• Your stop can be on another line. Yeogiya shows which line and direction to change to, plus the car and door for the quickest transfer, and reminds you at the transfer station.
• When the train leaves the transfer station, Yeogiya assumes you changed and keeps following you on the next line.

■ Works underground
• GPS doesn't reach subway tunnels. Yeogiya uses your phone's motion sensors to detect each departure and stop, and counts the stations.
• Location fixes caught briefly inside stations help correct the count.
• If it's ever wrong, tap "Wrong station? Fix it" to correct it right away.

■ Simple
• Open the app and your nearby station is picked using your location. Just search for your stop and start.
• Your 5 most recent routes are saved, so next time it's one tap.
• Choose when you're alerted: at every station, from 2 stops before yours, or from 1 stop before yours.

■ Korea-wide
47 urban and commuter rail lines in the Seoul metropolitan area, Busan, Daegu, Gwangju and Daejeon: about 1,300 stations.

■ Privacy
No sign-up and no ads. Location is used only after you agree to the terms on first launch, and location and sensor data are processed on your iPhone and never sent anywhere. When the app opens, it sends only basic info such as device type and app version to count users.

※ To keep detecting while you use other apps, Yeogiya uses your location while you ride (you'll see the location indicator at the top). It stops when you tap End. Continued use of location in the background can increase battery use.
※ Sensor detection can be wrong de
