Where is Support? – Pocket Ruler AR: How Tall Am I Review

I bought full version of this completely by accident and thought, well, I'm sure I can't get my money back but maybe I can use it. And at least there won't be any ads ... don't get me started on those cheesy (not hte word I want to use) ads.. There is no documentation that I can find to eliminate the ads or even how to ask questions of the developer. Where's the support website? How do I get in touch with the developer? The developer link is to a YouTube video ... not sufficient. I would give it zero stars if I could.
