I like this app, but I wish I could practice writing... or at least see what the writing lessons are like. Apparently, that is only available on a computer, and I dont ever use my computer... nor do I want to pay twice for the program. I can only imagine how hard this might be for me if I didnt already know the Korean alphabet... and some cultural things. Also, I wouldnt trust the pronunciation tasks because I know I passed some when I shouldnt have (meaning I said the phrase partially right but some of my words were completely wrong). Still though, if you already have some familiarity with the language you want to speak, the app can be very useful.
