I don't have the newest Ipad. I have the first one that came out. Still, I have managed to amass a collection of apps for drawing, painting and sketching. I've found them super-convenient substitutes for the real thing during my travels. This one started out as a doodle, and I added elements during subsequent sessions. I used an app called Art Set. I fell in love with it because its creators understand that simplicity and ease of use is the number one need artists have. I wish it offered more colors, though. I like it produces leaner files than say, Art Rage, which i also like. Also, I think that as they listen to artist feedback they will come up with "tools" that won't necessarily mimic what real life tools do, but that enable exciting effects.
