Good for iMac
I like this app. The drawings are fun and complicated enough for adults to enjoy. The only complaint with the drawings is that some times the lines between shapes do not stop the colors from bleeding into other shapes. This is a minor problem. The only other complaint is that while changing colors is not difficult, I don’t like to have to “create” new colors. A bigger choice of pallets would be great. But these complaints are minor. Considering the limited number of apps available for iMacs, I rate this one as very good. And yes, I will probably purchase additional coloring books in this app.
