[DarkBlaze]

Name and list some of the best apps those of you who have one or more of these devices. List them as free or the cost.

I've got a few good Japanese apps, some are pretty expensive as they are full dictionaries. Kana app is great if you want to learn Hiragana and Katakana.

There seems to be a lot of those apps. Saw a couple that were called Kana. So which one do you prefer? I wanna grab one of them.
