After installation, go to your settings and turn on private DNS. I had no ads. This is free. Google it. App is okay, but I think it's limited. For instance, I colored a peacock, but I couldn't give it metallic effect, which would be more realistic. Good app, though!

Too many adds. For example if you have service on your phone or using wifi you'll get an add every time you change color and sometimes just for the hell of it. Other than getting so over ran with adds. It's a good coloring app

Better than by number. They are real numb-ers. Haha
