Great for English Only Speakers – Seoul Metro Subway Map Review

I've been in Seoul for a couple days. I don't know any Korean, only English. This free version of the app is pretty good. The route planner is easy to use and helps you understand all the transfer points. If I could change one thing is maybe change the name of the Isu station to - Chongshin University (Isu). This is how it appears in the subway and in the trains. I freaked out thinking I went the wrong way, but then saw the (Isu). I'll be making the same case to Google maps because they are only showing Isu as well.
