Have you tried Affinity Designer on iPad? Very much like illustrator. As yet it doesn’t have a photo-to-vector converter but I wouldn’t be surprised if that is combing soon. I also have the desktop version for Mac and I even did a commercial project (a town tourist map) using it instead of Illustrator. It’s was handy to be able to display a project from my Mac on my iPad for a client meeting. Although, the iPad version doesn’t have every feature that is on the desktop version.Vectornator is really a nice tool on the mobile, VEEEEEERRRRRY inconvenient and awkward. It took me ages for one image – what I can do in Illustrator in half an hour.
To find out how it works is part of it. After the cat I knew at least how to do gradients. Now at the dog I even found a way to change the range … but it's all really complicated and you see nothing until you closed all the menus you have to go through to just change a colour of a tool. Well, at least I found I can also do a dog. In the darkest shades I've ever done. And because in the end it looks like a paperback cover I put the title in on my old phone that luckily runs still on iOS 10, because OVLA still works on 12, but because it doesn't appear in the list of privacy (same with glaze and so many other apps), you can't grant access to photos to save – though it easily picks from it.
Anyway here is the dog of my darkest hour:

On Xmax: Vectornator, on 6s+: OVLA
One place it is different from Illustrator, in addition to the vector layers it also has photo layers so it is like Photoshop & Illustrator combined.
