Hey guys, I was just wondering if anyone knows some iOS games like piano tiles that I could speed run, preferably a game with an in game timer, so I can just upload an image of my time, and not a video, because I find recording hard

Don't know any, but since iOS 11 and onwards there's a built-in screen recorder that's very simple to use. I'd look into that.

I can't think of any other games that don't require video off the top of my head, but a great place to ask the question would be the mobile speedrunning discord at https://discord.gg/F2fJjUg . You might find help with overcoming your problems with recording there too.
