I was really hoping that I could listen to lessons while sitting on my bed/couch with my iPad and going through the PDF and so on just by using the website, but it doesn't seem to work at all that way. Both videos and audio will not work unless I download them first play them natively on the iPad.
We're going to introduce the mobile friendly version of KoreanClass101.com soon (in one or two weeks.) We hope you'd be able to enjoy our lessons with the new version of the site.
