User reviews

Fix for no sound | Overall good app

For any one having issues with sound, make sure you do not have silent mode on.

Once that is fixed, the app works well although takes slightly too long to identify a video page. Still immensely valueable companion app for a book that has taught me so much already.

No sound

As some others reviewer also pointed out there still is no sound. The integration of the videos on the page is done very well which is why it’s very disappointing that this issue still isn’t fixed and apparently won’t be fixed. That sadly lowers the value of the product immensely
