Best or favorite iPad sketching app?

I just got an iPad.

What is your favorite iPad sketching app?

TIA!

I have sketchbook pro (fav), paper from 53, and wacom Bamboo paper. I use a stylus I got for $10 in chinatown. I think if you poke around there are some reviews on here of them. Sketchbook pro is nice that the price up front is all of it. Paper from 53 has you buy each thing individually, and I don’t think you can re-size you pen size.

My favorite sketching app is the assembly and sketch club.

Procreate.

I bought Procreate and found it to be horrible so far.
Medibang is my favourite after a quick few minutes playing with everything. I plan to have a proper go at getting good on Concepts though.
