Yup! Procreate has a built in recorder. So everything you draw gets recorded unless you turn the setting off.
I've only had it for a few days, but so far I'm loving the apple pencil! Its as accurate and sensitive as any wacom tablet i've every used. What most people are doing though is just using the iPad to create their sketches since its easy to use and portable. Then, they export their drawing to their program of choice and complete it there.
I'm glad I spent the money on it. Just yesterday I took a walk to the park, and finished the lineart for this wonder woman sketch in the (much needed) sunlight. Just the portability of it alone was worth it ^^
