Thanks! Great minds think alike. Just wasn't sure which app was more accurate. Am seriously considering learning Korean. A friend just got back from Incheon and said everyone was really nice, but spoke only a little English. My thought is that going to a foreign country, I should take the time to learn language and customs so I unintentionally don't offend and can get around reasonably well. I'll look into these apps and my local Korean school.
Once again, thanks to the helpful people on this fantastic forum from a long-time lurker and My Ajussi fan
