The short version
- Most visitors decide in seconds and never scroll past the first few screenshots.
- Published screenshot redesigns report conversion lifts from about 30% to 60%, but these are vendor-reported wins.
- The first two or three screenshots matter most.
- The only number that counts is yours. Apple's Product Page Optimization lets you measure it for free.
People barely look
In a 2017 study published on Phiture's ASO Stack blog, AppAgent founder Peter Fodor ran tests across SplitMetrics, TestNest and StoreMaven and reported that visitors spent an average of about 7 seconds on a store listing, and that only 9% of people scrolled portrait screenshots (13% across all tests).
SplitMetrics found something similar in a 2018 review of 1,800 A/B tests: only 11% of visitors scrolled through all five portrait screenshots, and 15% for landscape sets.
So for most visitors, your listing is the icon, the title and whatever screenshots fit on the first screen. That alone is a good reason to care about the first two.
What published tests report
All of these are case studies published by SplitMetrics, an A/B testing vendor, about its own customers.
| App | What changed | Reported result | Source |
|---|---|---|---|
| OLBG (sports tips) | Screenshot backgrounds, interface shown, screen order | 61% conversion increase overall, 45% in one test; the first three screenshots had the biggest impact | SplitMetrics case study |
| ZiMAD (Bubble Birds 4) | Rewrote captions, added the main character, mixed art with real gameplay | 32% more users tapped install | SplitMetrics |
| FiftyThree (Paper) | Chinese-localized screenshots vs English | Localized set performed 33% better | SplitMetrics |
For context on what you're competing with: MWM's catalog snapshot from April 2026 reports a median of 7 screenshots per app, with 83.6% of apps using five or more (apps with at least 1,000 downloads in the previous 30 days).
Caveats you should know
- It's vendor data. SplitMetrics sells A/B testing. Case studies are written to show wins, and failed or flat tests rarely get published.
- It's old. The dated studies here are from 2017 and 2018, and the case studies don't give test dates. App Store layouts and screenshot sizes have changed since. The direction likely holds; the exact percentages may not.
- Selection bias. Apps that invest in testing often start with weak screenshots, so there's more room to improve. A polished listing won't see a 61% jump from a redesign.
- Test pages aren't the real store. Third-party tools like SplitMetrics test on store-like pages that visitors reach through ads, which don't behave exactly like organic App Store visitors.
- Conversion isn't the only goal. Screenshots that overpromise can raise installs and lower retention or trial starts. Check what happens after the install, too.
What to do with your first two screenshots
- Lead with the outcome. The first screenshot should say what someone gets from the app, in a few words, not the app's name.
- Show real UI. Put the screen that proves the claim right under the headline. Visitors trust what they can see working.
- One idea per screenshot. A headline plus one screen. If you need two sentences, split it into two screenshots.
- Make it readable at thumbnail size. In search results your screenshots are small. Use big type and high contrast.
- Put your best feature second, not fifth. Few people reach screenshot five.
- Match the search intent. If most installs come from one keyword, the first two screenshots should answer it.
- Localize for your biggest non-English market. Translated headlines are cheap to test.
- Test it. Run the new pair against the old one before you assume it's better.
Measure your own lift with Product Page Optimization
Apple built A/B testing into App Store Connect. With Product Page Optimization you can test up to three alternate versions of your screenshots, app previews or icon against your original page. You choose what share of traffic sees a treatment, the test runs for up to 90 days, and App Analytics shows impressions, conversion rate, percent improvement and confidence for each version.
A practical approach: change only the first two screenshots, give the test enough traffic to reach confidence, and keep the winner. Then test the next idea.
Making the variants
The slow part of testing is producing good variants. Agent C designs a full captioned App Store set from your real screenshots in about a second, so you can make a few different openings, pick two to test, and send the winner to your App Store Connect draft. Designing is free; a finished set is $9.99. If you work in Claude Code, Cursor or Codex, the MCP server does it from your agent.

FAQ
Do better App Store screenshots increase downloads?
Published A/B tests say they can. Vendor case studies report conversion lifts such as 32% (ZiMAD) and 61% (OLBG) after screenshot redesigns. These are self-reported wins, and the dated research behind them is from 2017 and 2018, so treat them as proof that screenshots can matter, not as the lift you should expect. Measure your own with Product Page Optimization.
How much do screenshots affect App Store conversion rate?
There is no single number. Results depend on your app, your category and how weak your current screenshots are. What the data does show consistently is that few visitors scroll far: a 2018 SplitMetrics review of 1,800 tests found only 11% of visitors scrolled through all five portrait screenshots. Your first two or three screenshots carry most of the weight.
How many people look past the first screenshots?
Not many. An AppAgent study published on Phiture in 2017 found visitors spent about 7 seconds on a listing and only 9% scrolled portrait screenshots. SplitMetrics reported in 2018 that 11% of visitors scrolled through all five portrait screenshots.
How do I test whether new screenshots improve conversion?
Use Apple's Product Page Optimization in App Store Connect. You can test up to three alternate versions of your screenshots, app previews or icon against your original page for up to 90 days, and App Analytics reports conversion rate, percent improvement and confidence for each.
Do localized screenshots convert better?
In at least one published test, yes: FiftyThree's Paper app found Chinese-localized screenshots performed 33% better than English ones in a SplitMetrics test. If you get meaningful traffic from a non-English market, localized screenshots are worth testing.
