🧠 FSRS Intelligent Review

This app uses FSRS (Free Spaced Repetition Scheduler) – a more accurate memory model than the traditional Anki algorithm.
It dynamically calculates the best review time based on your performance on each card. Memorizing vocabulary is no longer haphazard; every word you encounter is one you're "almost forgetting."

Each Japanese word, example sentence, and 50-sound phrase has a TTS reading, with natural and non-mechanical pronunciation. The free version offers 3 standard human voices; a subscription unlocks 5 more Japanese human voices (Aoi, Mayu, Shiori, Daichi, Naoki) – male and female voices, lively and steady, choose your favorite accent to listen to.

✍ Hiragana and Kalavinka Stroke Order

Click on any kana (voiced/unvoiced/semi-voiced) to see the complete stroke order animation. Data from the open-source KanjiVG; the animation shows each stroke, making it easier to remember the correct writing order.
