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 3 screenshots above are GNSS View's answers to those questions — they're public, they're real, and they made it through Apple's review.
What the numbers say: GNSS View runs a dark set where the background shifts from screenshot to screenshot (first shot #242424) — each image has to stand on its own, so the captions carry more of the story.

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