Can anyone give suggestions on a good pixel art app that doesn't spam you with ads and doesn't restrict you to a 25x25 or such canvas size and let's you customize colors and save as transparent files? It does not have to be free, I just hate trying to find good reliable apps that won't mess up your phone lol. And if a stylus can be used with the app, even better. I would like to get one for my galaxy s9 ,(not plus) as I have more access to my phone during daytime hours than my computer. Thanks!
