Poor usage, not useful.
Must have app if you're in South Korea! Precise time table and easy to use app.
Very helpful once I got a hang of it. There are several display quirks that interfere with its use but I was glad to have it while in Seoul.
This app helped me a lot when i was in seoul and busan. Very precise, user friendly. Next year i am going to korea again and will definitely use this app again. Thanks!!!
Been using this app for years now... Then they started opening my browser and market for ads. In app ads? Sure, I'll help the developers pay for it WHEN I'M USING THE APP THEY MADE, NOT EVERY TIME I UNLOCK MY PHONE. Very disappointed.
The latest version of this app is opening ads in your browser or the play store after unlocking your device on occasion. High data and background data use.
Added Incheon Int'l Airport Terminal 2 station
Best Hyderabad Metro Rail App which provides Routes, Fares, Map, Gate Info.
