Kakugo
APK
Kakugo is an application that helps learning Japanese. It includes multiple tests to memorize hiragana, katakana, and kanji and adapts to the user's learning pace. One of the biggest difficulty with learning Japanese is memorizing kanji and vocabulary. While learning them by just reading and writing them everyday may work, the more kanji you know, the harder it gets and the more time it takes to revise them all. Proper tools can help you memorize these huge amounts of knowledge to more quickly become a fluent Japanese speaker. Kakugo is one of these tools. It helps learning and revising kanji and vocabulary in an efficient manner. It uses Spaced Repetition in a unique way that adapts to the user's pace. If you only have time to revise 30 kanji every day, or if you can revise as much as 100 kanji every day, Kakugo will adapt and test you on the right kanji at the right time for you to memorize them. There is no "kanji of the day" list to revise, you can start and finish a session whenever you feel like it. Kakugo also features a wide variety of tests to help you find the best ways that will help you learn Japanese. Features include * Hiragana, Katakana quizzes * Kanji quizzes by reading and meaning * Kanji test by part composition * Kanji writing test * Vocabulary quizzes by reading and meaning * Unique spaced repetition formula that adapts to your own learning pace * Unlimited quiz sessions that allow you to take a quiz at any time, for however long you want, useful to efficiently spend commuting time * Show similar-looking kanji in answers to teach you the differences * Kanji and vocabulary sorted by JLPT level * Clicking on kanji opens aedict3 (a non-free Japanese dictionary) or jisho.org * Optimized tablet support * Open source * No ads * No internet access required * Supported languages: English, French * More to come Credits * The kanji quizzes are based on kanjidic. * The vocabulary quizzes are based on JMdict. * The kanji similarity database comes from https://minerva-access.unimelb.edu.au/handle/11343/35336 and http://lars.yencken.org/datasets/phd/ * The kanji composition and drawing database comes from KanjiVG.

Kanji draw
APK
A simple application that lets you draw Japanese characters (kanji) using the touch screen. It is intended for Japanese language learners who might need to enter characters in order to look them up in a dictionary or enter them on a website. It identifies the character you have drawn using a special form of handwriting recognition. You can select the correct character from a list. After entering one or more characters, you can copy them into the clipboard as text for use in a dictionary. Note that this will NOT work - at all - if you don't know basically how to draw kanji. If you just draw something any old way that looks like it, it certainly won't be recognised. You have to draw characters basically the official way. This is a fork of the Kanji draw application from https://github.com/quen/kanjirecog/ which is no longer maintained and was removed from F-Droid. Two of the included icons were taken from the Android SDK and are licensed under the Apache License 2.0. The kanji stroke data is based on the KanjiVG data set from http://kanjivg.tagaini.net/ and licensed under the Creative Commons Attribution-Share Alike 3.0 license.
