JA Sensei 4.3.2 is available on Google Play. Here is what's new:

• Possibility to add your personal comments for each word/kana/kanji (add your mnemonics for example!)
• Personal comment synchronization and backup between different devices and the website
• Multiple-session quiz: abort a quiz whenever you want, and finish it later without having to redo it from square one (very useful when you only have a few minutes several times in a day)
• "Kanji Analysis" and "Kana Analysis" sections added for each word in the Vocabulary module
• Kana/Kanji/Word sheets improved
• Kana: fixed compound kana that would be drawn off the screen
• Other minor bugs fixed
