KanjiBox for iPhone 0.5

About KanjiBox

icon KanjiBox is an iPhone application to help you study Japanese. It provides a set of simple, yet powerful, drill exercises to help you evaluate and improve your skills in specific aspects of Japanese studies: kanji, vocabulary, kana etc.

KanjiBox is particularly well suited for standardised test preparation (JLPT, Kanji Kentei, Ninja academy...) but works perfectly well as a standalone self-study tool.

This iPhone version is a port of the popular and free KanjiBox for Facebook application, although not all features of the original have been implemented yet.

What Makes KanjiBox Unique?

Like most great teachers:
  • KanjiBox is Smart: it records all your answers (good and bad) and uses a special adaptative algorithm to decide which questions to ask you next, in such a way as to optimize your learning curve.
  • KanjiBox is Mean: choices are automatically selected to make guessing difficult. For example, kanji always come in pairs of closely (and often confusingly) similar characters.
  • KanjiBox is Engaging: live bar charts showing your skills in each area provide you with an incentive to keep studying until you get the coveted "all green" bar for a given level (timed quiz mode and highscores are also coming very soon).

Current Features

  • Study at your level: JLPT 4 to JLPT 1, and an extra "Sensei" level (with all 6,000 kanji and 20,000 words).
  • Adaptative learning: focuses on your weak points.
  • Live bar charts: displaying your current performances for each level in each mode, real-time.
  • Kana mode (hiragana and katakana).
  • Kanji mode (over 6,000 kanji):
    • Optional display of pronunciation (onyomi, kunyomi) and English meaning.
    • Special kanji-similarity algorithm, to make "intelligent guesses" more difficult (yes: this is mean, but so are the people who make the standardised tests you will take one day).
  • Vocabulary mode (over 20,000 words):
    • Configurable furigana (word reading) display.

Known Issues

  • On some of the higher levels, drill screen can take some time to load and will sometimes freeze a couple seconds mid-game. This is mostly due to hardware limitations and the size of the database. Hopefully this will improve over time as I keep adding optimisations into the code.
