For iPhone not iPad

Purchased this for my ipad. Will only show as 1/4 screen size. I can only see 1/4 of the instructions page (or less) at a time. The image is hard to read and controls difficult to discern. No idea how well it actually works because I cant see it well enough to actually use it! I want my money back! Beware!
