I have been drawing on my iPad pro for a bit but been having trouble with apps not giving me a clear resolution or enabling me to resize... I wonder if there are any other individual here who draws and do all editing on iPad who can give me some help on what app is good to do all of this of a computer can? Or... do I just need to give up and invest on a computer?

I'm not.. that good with drawing or anything but I do doodle and outline a lot on Procreate - which I recommend. You can resize any time you want and it's pretty clear as well. It's not a free app, though. :c

I use Procreate as well for drawing on my iPad which works similar to adobe Photoshop. It should allow you to resize.

Most of the free ones I’ve found tend to give you a Pre-set size that the canvas is locked too.

　 Thanks so much! I've heard good stuff about Procreate, just never could find any good tutorial video showing me how to resize... I think regardless it's an app I'd want to try

I draw on my galaxy tablet, so I'm not sure if it's on ipads, but I found a great app called artflow!
