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.

What the numbers say: Heeler for herdr runs a dark set with one background colour (#04040C) 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.
