When i was in college I made a painting app for desktop and now I have converted it into an android app and its completely free, not even ads are in it.
I have seen a lot of free drawing/painting apps in play store but they all have ads in it which really interrupt the creative process.I made this completely free so that artists can have an uninterrupted creative experience.
I have tried to cover all the basic and advance features that an artist would want in the app. Try it out and let's build a community around this app. Thanks and enjoy
