Ratings and reviews

Solid app, I'm not sure what is going wrong for other users. I installed the app and used the built in barcode scanner to scan the top right barcode on the back of my Genki book. It then pulled the relevant audio files. I have now downloaded lesson one and two and am listening to the audio with no issue. Very well designed, easy to use and navigate.

Great app to hear native pronunciation while studying Japanese. I'm giving 4 stars because at the moment the application is a little barebone. To get 5 stars I would suggest the addition of user playlisting functionality. This would allow users to, for example, make a "vocabulary" playlist containing all the audio of the vocabulary they have studied so far, so they don't need to go back and forth between lessons to find the content they need.

My textbook audio keeps fading in and out. There is no option to disable this feature and it's causing me poor homework scores.
