Zbrush For IPad tutorials?

I’ve tried (and failed) to break through the steep learning curve of zbrush several times - but the unintuitive UI crushed me. I’ve heard that the iPad version is a tad more intuitive, and want to get back on the zbrush horse! Here’s the deal: I’ve got 20 hours of flying coming up, and would love to devote that time to learning the software. Now, I know it’s very new - but are there any tutorials or guides you’d suggest? I may not have wi-fi, so bonus points if I can download the content. Thank you for any and all pointers!
