What I use to create my doodles:-
I have a 2017 iPad Pro 10.5” with a gen1 pencil and I use Autodesk Sketchbook for the drawings. I have tried many other apps but never found something that comes close for me. Although I haven’t tried Procreate.. yet!
For my pictures I use predominately my iPhone but i do have a Canon Ixus 220HS that I use as a backup on trips and when I need a bit more zoom. I have contemplated getting a “proper” camera but I so far haven’t come across a image that has been let down by the iPhone.
