Tokkun · special training

Tokkun is for practicing katakana.

Why katakana? In typical Japanese text, katakana doesn't show up as much as hiragana and kanji. Katakana is only about 6%¹ so it's hard to get enough practice with it for it to feel natural to read.

In this app, a katakana word appears and you type the reading in hiragana. Over time it learns which characters you keep missing and which ones you mix up (e.g. シ and ツ, ソ and ン), then it shows you those more often so you can get more practice in your weaker areas.
