JLPT Words is a helpful tool to learn Japanese and prepare for a JLPT exam by studying JLPT vocabulary. It contains a dictionary of words required for the exam that can be searched on using kanji, kana (hiragana/katakana), or romaji. You can filter the dictionary by JLPT levels and each word is colour coded according to its level. It currently contains vocabulary for JLPT 3, JLPT 4 and JLPT 5 - more will be added soon. You can test yourself using a configurable quiz to learn Japanese quicker. The options allow you to select:* JLPT level,* English to Japanese or Japanese to English quiz,* entry type: multiple choice using buttons or text entry,* script used to display questions and answers (kanji, kana, romaji),* number of questions,* how learning progress is used to select words for questions. The application tracks your learning progress and displays it against each word. To make your learning easier, words that you know less are selected more often for questions in the quiz. You can also filter the dictionary of words by learning progress and JLPT levels as well as hide and show translations. The application is ad supported. JLPT Words uses Flurry (www.flurry.com) to gather anonymous statistics about the application usage, users' handset and country. No detailed information about location is gathered. The statistics help me to understand how the application is used and make it better.
