The best app would definitely be Procreate it’s definitely worth the cost. When I purchased it I got it for 13.99 but it was worth the really great features. I love to try out everything, I also like if you have a apple pen it feels like you are actually writing and painting. It can make skin look real, trees, you can draw animation, you can paint with all of watercolour, pastel, wet acrylic, oil, stucco, fresco and much more.
The brushes range from wet, old, round, damp, jagged, dry and more as well. I really found there is literally every pencil, pen, and marker for any project you can think of. I drew a few I want to share but I’m just beginning I will be sharing a lot more detailed ones in the future.
I can imagine someone who has incredible skills can do better but it gives beginners a way to have affordable art creation without buying all those art supplies. I’m so greatful.
