Whenever I'm making a new app or changing app categories I end up having to look this up again so I decided to make a quick cheatsheet page for easy access. The Fastlane documentation is great but the stuff about categories is buried in a pretty long page and I always have to spend a minute or two searching for it. Here it is:
I'm not really sure why some of the gaming categories still have 'MZGenre' in them. Anyway, I hope I was able to save you a couple of minutes with this page. Goodluck with your new app!
