Version 1!
Just the Seoul subway map, no bells, whistles, or other complications. Always available offline! You can zoom the subway map in, zoom it out, and that's all. Very simple and easy to use! Opens to the Seoul subway map immediately so you can quickly decide if you need to hop on the train in front of you, or wait for the next one. I've also tried to keep the size down so anyone can install it, no matter how little space you have left :)
This app is excellent for visitors to Seoul and longtime residents alike.
Support indie developers! If you have any trouble with the app, PLEASE EMAIL ME at the address below before rating poorly: I'm very responsive by email, but I rarely check ratings. Thank you!
