Too many ads..... I love these painting by numbers apps, they are good for relaxation, this one has loads of different pictures, really good ones, easy to use, zoom in and out, move picture around, some easier than others, something for everyone, however, ads have definitely spoiled it for me, find it irritating and annoying so ruins the idea of relaxation. Ads before, during and after picture, recently changed ads so difficult to close. Other than ads, its great but may stop using now.
