Good buy

Ive been using this on the train while going to work. Today I opened up a JLPT Level 2 textbook and noticed a lot of words I had been studying were used in the practice reading questions. I would like to add more words to my app, but am worried about doubling up on some of them, a dictionary function may be good to help guard against that. But as of now, I am very happy with my purchase.
