The app has only been given 3 stars for these 2 reasons: 1, no variety of colors in the choice of shading. I have some vision problems and the gray shading isn't easy to find. 2, no long tap to change colors. Now on the positive side, great variety in different picture choices. Had given this app 3 stars earlier. The 2 reasons above were why. They said they had a 2022 update that addressed them. Nope. Going to uninstall again.
