How do you improve App Store screenshots with AI? The exact prompt.

I am Samet Durgun, a fractional Head of UA. I run paid UA for subscription apps and mobile games and write up what I find in the accounts I manage. This piece sits under how ad production works and what it costs; more about me.

When I work on screenshot strips, I want competitive insights instead of vague “design feedback.”

My process has three steps:

  1. I upload my screenshots as a strip (one image with all screenshots in order)
  2. I add 10 reference strips from top apps in the category
  3. I use this prompt:
Task:
I'll upload my new screenshot strip plus a folder of 10 reference
screenshot strips from top competitors.

Output format:
Give me a Markdown table with three columns:
- Change to make (one short sentence)
- How many leaders already do it (X / Y form)
- Why it matters (one short sentence)

Rules:
- Use exact app titles
- Keep language simple
- No row should run longer than one sentence
- Flag anything done by fewer than 5 / Y apps as experimental
  in the "Why" column
- End with a one-line summary
- If you have extra points to tell, be proactive, don't make me
  miss important things

What this gives me:

  • Feedback backed by data instead of design opinions
  • Priority ranking based on what successful apps do
  • Clear next steps

One row from an example output: “Add download count” (8/10 do it), because social proof drives downloads.

How I act on each row

  1. I look at the reference strips and confirm the count myself before I act on a row.
  2. I start with the highest counts. Changes that more leaders already make come first, and anything done by fewer than 5 of the 10 carries the experimental flag in the “Why” column.
  3. If the change puts a claim on the screenshot, like a download count, I only show a number the app can back up.
  4. Each row is a test, and I judge it on the app’s own store page conversion.

I work this way because screenshot work should start from what category leaders do and end with what my own test shows.
