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 4 screenshots above are ShakeWatch de SeismicAI's answers to those questions — they're public, they're real, and they made it through Apple's review.
