Great but buggy – ArtStudio - Draw and Paint Review

I love this app and use it the most on my phone as a substitute for Photoshop. But it seems at random the app can crash and it'll erase all the work you've done so far on it. On top of that, if you're using the pencil tool a lot, sometimes little squares start appearing everywhere and the only way to get rid of it is by undoing your stroke. There should also be a history sidebar option as well because if you ever close the app out of the background, you won't be able to undo anything you've done prior to leaving.
