Overall its a decent tool. Some of the definitions are, well... a bit off. I think the most needed feature would be questions with the English word requiring you to draw the kanji. I dont feel confident recognizing kanji until I can successfully draw it. Voice would be nice but not necessay. Considering buying the full version. Its a done deal if the kanji drawing feature is added.
