Nothing more disappointing than ads And no, buying the ads off like the developers respond to me it's not an excuse, make the app paid or don't market it as free, you could even find a way to put ads if someone chose to watch them to earn some gems or something in a reward system that wouldn't ruin the experience, artists then could buy brushes or something with this gems, things that are not vital to produce creativity, putting forced ads in an app thats based on creativity and art is unethical
