Scott E on App Store. Product complaint.

Can you please provide an example of another hardware, software or plugin company that provides such an app?
I don't want to overlook a resource like that if it's available to me.
I'm especially interested in:
Avid (Pro Tools), Logic Pro X, Cubase (8.5), Harrison Mixbus, Waves plugins, iZotope plugins,
Steven Slate Digital Media and, for that matter, Apple's OS X operating system and Macbook Pro hardware.
As far as I know, none of these companies offer a training app of their own creation...but maybe you've encountered one.
However, I do know that MacProVideo, Groove3, Lynda.com, and CreativeLive among others have created training courses & videos.
Most offer a subscription service allowing students access to their entire catalog for the duration of the subscription.
I've used these and highly recommend them.
Also, there is a near endless list of books covering many of the major interests.
I've used these as well and highly recommend them, too.
