### 3/5 — Useful app for pitch accent with some caveats

*2025-10-17, version 3.1.9*

The app is useful for its original intended purpose but the AI additions are gimmicky. I see there is an option to turn AI explanations off now, which is handy. I suspect some of the entries themselves are AI generated, as are the pronunciations, albeit in very realistic voices. I’ve noticed examples of database entries showing and speaking pronunciations for readings that don’t exist in Japanese, for example, giving an on’yomi reading and audio recording for something that is only ever read in kun’yomi.

### 5/5 — 잘만든 앱

*2024-10-20*

사람이 검수하지 않고Ai가 잘못 악센트를 기재된경우
틀리게
암기할수 있다는 부작용 우려를 없게 해주네요
찾아보니 다 맞습니다
이런 악센트 사전 유료로 구매해도 몇십만원짜리인데 감사합니다

**Developer response:** 좋게 봐주셔서 감사합니다. 말씀하신 것처럼 AI가 악센트를 잘못 표기할 가능성은 저희도 중요하게 보고 있으며, 더 정확하게 만들 수 있도록 계속 개선해 나가겠습니다. 소중한 피드백 감사합니다.

### 4/5 — Its great!

*2024-10-18*

I use this app a lot to help me determine the pitch accent of a word so I can speak more naturally. This app is very helpful with that. Although, I do find that sometimes I cannot find a pitch accent of a word. Are words being added to Jaccent? Also a note to the developers I think a cool thing you could make is maybe a guide to pitch accent. With lessons and how it works. Just a suggestion. I highly recommend this!

**Developer response:** Thanks so much — we’re really glad Jaccent is helping you with pitch accent and more natural speech. Some words may still be missing from the dictionary, and we’re always working to improve coverage; your idea for a pitch accent guide with lessons is a great suggestion too. We really appreciate the recommendation!

### 5/5 — 很方便

*2024-10-04, version 3.1.6*

推一個

### 3/5 — Display Problems

*2024-09-25*

This is seems good, but I am unable to full appreciate it because of a bug which prevents content from being displayed.

Most screens are not displayed and are instead replaced with a solid gray screen. The kanji tab works, but the actual definition screen does not, basically making the dictionary useless. I also cannot access the profile tab and chatbot. The flashcards tab is just a loading circle.

I have been trying to use this app for a few months, but it these issues are preventing me from doing so. I’m not sure if others are experiencing such issues, but I would appreciate is they could be resolved. Thank you.

**Developer response:** Thank you for using our app and for taking the time to share your feedback! The issue you experienced may have already been fixed in the latest version. Please update the app to the latest version and give it another try. We hope it works well for you!

### 5/5 — 굿

*2024-09-12*

일본어 공부중인데 편리하네요. 영어 발음기호처럼 일본어도 일반 사전에 발음 정보가 있으면 좋겠어요. 일본은 돈도 많은 나란데 이런거 정비는 왜 안 하는지...

**Developer response:** 좋게 봐주셔서 감사합니다. 말씀하신 것처럼 일본어도 영어 발음기호처럼 한눈에 보기 쉬운 발음 정보가 더 잘 보이면 정말 편하실 텐데요, 이 부분은 소중한 의견으로 잘 참고하겠습니다. 일본어 공부에 도움이 되도록 더 보기 좋고 유용한 정보 제공을 계속 고민해보겠습니다.
