Description by Rio Otomo Written by the developer, not by AppBrain. Click to read.
The app uses spaced repetition to schedule reviews, so you spend your effort on the grammar points you're most likely to forget.
Study modes:
• Grammar Drill — fill-in-the-blank exercises covering grammar patterns at every level.
• Particle Practice — focused practice on choosing the correct particle, with answer choices drawn from genuinely confusable particles rather than random words.
• Speaking Practice — say example sentences aloud and get on-device speech recognition feedback, with relaxed matching so minor transcription differences don't count against you.
Each mode tracks your progress separately and schedules reviews independently, so your speaking practice and your written drills each follow their own pace.
All study data stays on your device. The app has no accounts, no ads, and no tracking.
A one-time small purchase unlocks the full set of exercises across all levels.
