KoiJLPT

Learn Japanese the smart way. FSRS scheduling you control, every word with a memory aid and example sentences, and your whole JLPT deck offline. One-time purchase.

Koi JLPT is a vocabulary trainer for the Japanese Language Proficiency Test, N5 through N1.

You review a handful of cards each day, and the app schedules the next review right before you'd forget the word. Cards come with furigana, pitch accent and example sentences, and there's a romaji option if you're just starting out. When you're tired of flipping cards, switch to multiple choice, dictation, or kanji stroke-order practice.

Point the camera at a menu or a book page and Koi reads the Japanese, lets you tap any word for a definition, and saves new words straight into your deck. Everything runs offline & no account, no subscription.

Built by one person studying for the JLPT who wanted an app that just does the job.
