Oboete: Japanese Vocabulary

Learn 10,000+ curated entries with FSRS, offline audio and a 217K-entry JMdict dictionary. Use smart reminders and widgets, then sync progress via private iCloud.

Oboete — remember every Japanese word the smart way.

Still grinding through vocab by brute force? Oboete puts the research-backed FSRS spaced-repetition algorithm in your pocket: it schedules each review right before you're about to forget, so you remember more in less time.

■ 15 word books and 10,000+ curated entries Study 4,939 core JLPT words from N5 to N1, plus 10 supplementary books grouped by lesson. Every entry includes kana, part of speech, a natural example and a memory hint. Choose exactly which books feed your daily queue.

■ Smart FSRS reviews Based on your "Forgot / Unsure / Got It" feedback, the algorithm finds the perfect moment to review. The longer you study, the more time it saves you.

■ Offline Japanese audio Hear the kana reading from either side of a card with one tap. Speech works offline and mixes with audio already playing.

■ Offline 217K-entry dictionary Search the bundled JMdict dictionary without a network connection. Inflected Japanese can be restored to its dictionary form, and any result can be added directly to your study queue.

■ Widgets and smart reminders Home Screen widgets show due reviews, new words and your streak. Optional reminders use your actual due cards and remaining new words, support a custom time, and stay quiet when there is nothing to study.

■ Private iCloud sync Your progress, review state, streak and settings sync between devices through your own private iCloud database; word books remain bundled offline. The developer does not receive or collect your learning data, and the app contains no ads or third-party tracking SDKs.

■ Three interface languages Use Oboete in Simplified Chinese, English or Japanese, with Dark Mode and layouts for both iPhone and iPad.

■ Free & Full Version N5, N4 and matching beginner supplementary books are free forever. One purchase unlocks N3, N2, N1 and advanced supplementary books. No subscription, no ads, yours for good.
