  • A japanese Dictionary App that works exactly like Pleco?
    Http://nihongo-app.com Iโ€™m surprised no one ever mentions this app. I have both Pleco and this app I linked.

They each have their pros and cons but the app I linked has what you want and more. Source: over 3 years ago

Basically, they teach you (1) the kun-yomi word(s) for each character, (2) the 1-3 most common words for each on-yomi, and (3) to write the kanji. Don't try to learn the readings in isolation, learn them in the context of... - Source: Hacker News / over 3 years ago
