This is the companion app for the new Design Studio Press book: How to Draw.
Enhancing the learning experience, this app has been created to allow readers to use trigger images on pages to link directly to online tutorials via their iPhones and iPads. Using advanced video techniques, this app connects the printed matter to online digital educational content as never before, and insures that the book remains as current as the rapidly advancing techniques presented in How to Draw. Over 10 hours of video content have been created to accompany the book.
A physical copy of How to Draw is required to get the most out of the h2Dr app. Additionally, an internet connection is required to view the video content.
You can get your copy of the How to Draw book by visiting:

No itemized purchase list is available for this listing.
Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.
Write to [email protected], or use the form. Name the finding, the app version and the evidence that needs correcting. Factual corrections are free and never depend on buying anything.
