Korean Tutor has many words to use in your daily life. I teach English in Korea and so I made all the words I use into one app. The vocab here is what I have taught to my awesome students. The vocab is quite large, but none the less, all of the words are commonly used and helpful. It doesn't matter if your learning Korean or English, it works both ways. If you are on the bus or in the country, no problem as it works offline.
