Reviews

Great, but…

The audio quality is really great, pronunciations are clear, you can adjust speed and it doesn’t sound distorted. They did a great job there. However, when you add a single track/lesson to favorites, the entire book gets added. I’m hoping this is just a bug that will get fixed but if it’s intentional, it kind of defeats the purpose of having a favorites list unless you’re going to offer favorite books AND a separate favorite track list.

Can’t find the audio

This app literally gives you instructions of where to download the audio when I can’t even find that option.

Doesn’t recognize quartet book

It just gives an error when scanning the code.

It works and it’s free

I’m currently about halfway through the Genki Vol. 1 textbook (self-study) and so far I don’t have any real complaints about this app. I mean, it’s free and it works well enough. What more could you ask for?

I recently purchased the third edition of Genki and it told me to install this app to listen to the audio for the lessons, however the app doesn’t let me download or veiw those lessons.
