Well, yes this is an awesome app. Its incredibly useful and very helpful as just another method to practice my kanas. I definitely recommend this to anyone learning.
Although my one gripe is having the go, ji, zi, etc (you know the ones with the double hatch marks to the upper right hand corner) with the normal ka ki ke ku ko and so forth, I feel as though Im not learning those as an individual kana so much as just adjusting the other ones. Although I guess thats not so much a complaint as a suggestion. Either way this is still a fantastic app. Worth the money.
