Ipad Air and Pencil getting delivered tomorrow. I've been an avid iphone user/gamer since the 3gs, but since I didn't have one pretty much always ignored the iPad-only apps. Opted instead of upgrading my XR this year to an 11, I'd finally get an iPad. I know I need to buy the ipad version of Procreate, but I'm pretty unfamilair with the iPad exclusive app ecosystem. What other must have apps/games exist exclusively for iPad that I need to know about and get?
