Incomplete... I feel ripped off

Let me first start off by saying that this app is really effective, in terms of learning the standard hiragana. I love it, however, there one HUGE flaw

For $5, I expect an app that is complete in hiragana... but it isnt. On top of the normal hiragana, there is modified hiragana, which is not only critical, but should also be included in my purchase... Yet for some reason, this app only quizzes you on it, it doesnt teach you.

This app needs a serious update that covers the modified hiragana with a learning mode, reference guide, and sound effects of all the the letters/symbols/characters outside of the normal hiragana. The same goes for the katakana app
