Doesn't fit iPad screen – Nonogram - IQ Logic Pic Puzzle Review

I downloaded the free app for my iPad and it worked great at first. But as I got to larger puzzles I noticed that the last row was being cut off partially until it got to the point where I couldn't see it at all. I noticed that there was an ad banner along the bottom, so I thought I had to buy the ad-free version in order to see the rest of the puzzle. It annoyed me, but I wanted to keep playing so I paid to get rid of ads. All that happened is that there's a blank white strip along the bottom and I still can't see the bottom line. There is a zoom in and out button but it only goes one step in and one back out to the original view, so that's no help. I also checked settings and there's nothing in there to change the screen size. Unless this is changed this app is NOT worth downloading.
