In search results, shoppers see your first screenshot — sometimes the first two — without ever opening your listing. For most visitors, slot one isn't the beginning of your story. It's the whole story.
Slot one is your thesis
Lead with the single strongest reason your app exists, phrased as the user's win. If people know your category, show your difference; if they don't, show the outcome. Either way, slot one should work as a standalone ad with the other four screens deleted.
Order your screenshots like newspaper headlines: if they only read the first one, did they get the news?
The swipe is a bonus, not a plan
Screens two through five still matter — they close the reader you've already hooked. Use them for proof: social numbers, key flows, the delightful details. Just never put the hook itself anywhere but first.
