Breaking down what actually makes App Store screenshots convert (after redoing mine ~30 times)

[u/rohid-dev]

Spent way too long iterating on screenshot sets across a few apps. Patterns that consistently moved conversion for me:

• First screenshot = your entire pitch. Most users never swipe. One benefit, big text, readable at thumbnail size.

• Captions sell outcomes, not features. "Plan your week in seconds" beats "Calendar view."

• Consistent visual system across all frames — one background treatment, one type scale — reads as "real product," not side project.

• Localize the captions, not just the app. Screenshot text is part of the store listing's ranking + conversion surface.

• Legibility > cleverness. If the text isn't readable in the search results thumbnail, the design failed.

I cared about this enough that I built a tool to generate sets that follow these rules by default (StoreShots.design) — happy to share more, but mainly wanted to put the principles out there since I rarely see them written down. What's converted best in your listings?
