App details
What you can learn from PrismKit
Every shipping app on the App Store has gone through the same decisions you're working through right now: which screenshot goes first, what caption sits over it, which device frame to show, what color the background should be. The 20 screenshots above are PrismKit's answers to those questions — they're public, they're real, and they made it through Apple's review.
What the numbers say: PrismKit runs a mixed light-and-dark set where the background shifts from screenshot to screenshot (first shot #0C0C14) — each image has to stand on its own, so the captions carry more of the story. The accent colour we picked up, #A47CE4, is the one to reuse for badges, arrows and highlighted words if you borrow this look. Hit Use this style to open the editor with these exact colours and drop your own screenshot in.
Notice the first screenshot in particular. It's the one users see in search results and on the product page, and it's where most apps spend their best caption and tightest design. Look at the proportion of background to phone, where the text sits, what one thing the image is trying to communicate.
