I found that the apple app store had plenty of good free accent dictionaries but my options have been limited since I switched to android. I'm glad this app is also available for Android because it's exactly what I need - simple, easy to use, and has the accent information I need. So far it's the best Android app I've found to use as my everyday Japanese accent dictionary. Thank you!

I really enjoyed using JAccent. The app is simple, user-friendly, and helpful for learning Japanese pronunciation. The lessons are clear and easy to follow, making practice convenient even for beginners. I especially like the focus on Japanese accents and pronunciation, which makes learning more practical. The interface is clean, and the app runs smoothly without feeling complicated. Overall, JAccent is a useful learning app for anyone who wants to improve their Japanese speaking.

Hello there! How are we supposed to know if the particle attaches high or low? Without listening to the sentence at least. Now the app is pretty good, it's simple and easy to use, but there's that one major issue. Please add either a particle in a different color, a number indicating when the pitch drops or add the category names (heiban, atamadaka, etc.) or better yet, all of them! I would absolutely adore this app if this improvement was made! I look forward to future updates! :)
