Absolutely Phenomenal

I’ve tried countless apps and courses to learn Japanese, but none of them even come close to this one. It makes memorization incredibly fun through mnemonics, and the built-in spaced repetition system (SRS) handles long-term retention perfectly—completely saving you the hassle of making separate Anki cards. It’s a comprehensive, well-rounded app that covers hiragana, katakana, kanji, and vocabulary. At $25 for full access to all the resources, it is absolutely worth it.

어려운 한자를 쪼개서 기억하기 쉽게 이미지 만든 것도 좋아요. 일러스트도 보면 이해하기 쉽도록 그려서 있고 예문의 설명은 간결하지만 필요한 정보는 다 있어서 다른 사전을 찾아보지 않아도 됩니다.
