Excellent
I use this app very often and I like it, however I wish there were more Kanji in this app. The current number is 1715 and that is not even the full amount of the 常用漢字, which is 2136. I strongly suggest adding all of the kanji within the 常用漢字 Also I noticed an error in the app, the word 「衣服」has the wrong reading. It should be 「いふく」but the app says it's 「いるい」(衣類)
