IPad as a graphic tablet?

A real drawing tablet will definitely be better, although I have never used one before.

But if you can't afford a tablet, an iPad is not a bad option if you're on a budget.

There are many great drawing apps that you can download from the app store like Procreate, Sketchbook, Art Set, etc. They are relatively cheap. I got Procreate for around $6, Art Set for around $3, and so on.

I drew these on my iPad so it's definitely possible.
