There are better nonogram apps – Picture Logic Puzzle - Nonogram Lite Review
The interface and the method of filling in the grid is tedious, the English is pretty.. Well, bad, and I only made it through two of the practice puzzles before I reached one that could not possibly be solved. I don't like writing cruel reviews, but this is an app I won't be touching again unless I see they've updated it and it's getting better reviews.
