I used Art Set 4. Wanted something relatively basic while I don't know what I'm doing, if not in general - I do tend to favour a limited tool set when it comes to creative pursuits (too many options can be a killer, I am easily intimidated and mildly technophobic, etc). Will probably try a few more of the more basic apps, though, and see which of them I like best. I'm definitely experiencing some degree of negative gut reaction - feels a bit unnatural and wrong for sure, not least since it's aNother screen in my life; but, at the same time, I am probably hooked đ
