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 5 screenshots above are Cosyra: AI Coding Agents's answers to those questions — they're public, they're real, and they made it through Apple's review.
What the numbers say: Cosyra: AI Coding Agents runs a dark set with one background colour (#040404) carried across every screenshot — the listing reads as a single poster when the shots sit side by side in search results.

Hit Use this style to open the editor with these exact colours and drop your own screenshot in.
