11 App Store Screenshot Mistakes (and How to Fix Them)
Your screenshots are the single most-viewed asset in your entire listing. Most people never read your description — they glance at your icon, your title, and the first two or three images, then decide in a few seconds whether to tap "Get." If those images are blurry, off-spec, or just a wall of bare screens, you're leaking downloads before anyone even reads a word.
In short: the biggest app store screenshot mistakes are using wrong dimensions, posting uncaptioned raw screens, burying your best message, and ignoring localization. Below are the eleven that cost makers the most downloads — and the exact fix for each. For the full spec side of this, keep our app store screenshot sizes guide open as your reference.
1. Using the wrong dimensions
This is the mistake that gets you rejected before your listing is even reviewed. Both stores enforce exact pixel sizes, and an off-spec image is refused on upload.
| Asset |
Required size |
| iPhone 6.9" |
1320×2868 |
| iPhone 6.7" |
1290×2796 |
| iPad 13" (M4) |
2064×2752 |
| iPad 12.9" |
2048×2732 |
| Google Play phone |
1080×1920 |
| Google Play feature graphic |
1024×500 |
Fix: Export at the exact spec instead of resizing screenshots by hand. The App Store screenshot generator outputs each of these sizes directly, so you never get bounced for a stray pixel.
2. Uploading raw, uncaptioned screenshots
A bare screen with no context makes the viewer do all the work of figuring out what your app does. The winning pattern is a device frame plus a short benefit headline above or below it.
Fix: Add a one-line caption to each image that names a benefit, not a feature — "Split bills in two taps," not "Payments screen." Our guide on how to make app store screenshots that convert breaks the caption formula down in detail.
3. Burying your best message
Many makers order screenshots by app flow — signup first, settings last — instead of by importance. But the first two or three images do almost all the persuading; most people never swipe past them.
Fix: Lead with your single strongest benefit, then your second, then your third. Treat screenshot one as your headline, not your onboarding screen.
4. Writing captions nobody can read
Tiny caption text, low-contrast colors, or a font that fights the background all make your headline useless on a small phone thumbnail in search results.
Fix: Use large, bold text with high contrast against a solid or simple background. If you can't read the caption on a thumbnail-sized preview, it's too small.
5. Showing placeholder or debug content
"Lorem ipsum," test user "asdf," or a visible debug banner will get your listing rejected and instantly kills trust if it slips through.
Fix: Populate the app with realistic, final content before you capture screens — real names, real-looking data, no dev artifacts.
6. Inconsistent visual style
Screenshots that each use a different background color, font, or layout look slapped together and cheapen an otherwise good app.
Fix: Pick one background palette, one caption font, and one layout system, and apply it across all images. A consistent set reads as a polished, intentional brand. Start from a proven layout in our app store screenshot templates roundup instead of designing from a blank canvas.
7. Ignoring the first-glance thumbnail
Search results show your screenshots small. A design that looks great full-screen can turn into an unreadable smudge at thumbnail size — where the actual decision happens.
Fix: Preview your set at a small size before publishing. If the message doesn't survive shrinking, simplify the composition and enlarge the text.
8. Skipping localization
Serving English-only screenshots to users browsing in other languages leaves conversions on the table in every non-English market you're available in.
Fix: Localize your caption text for your top markets. Even translating just the headlines on your first three screenshots can lift conversion where you have meaningful non-English traffic.
9. Mismatching screenshots and the actual app
Screenshots that show features you don't ship, or an old UI you've since redesigned, are both a rejection risk and a source of angry one-star reviews from users who feel misled.
Fix: Recapture screenshots every time you ship a meaningful UI change, and only show features that exist in the current build.
10. Wasting your screenshot slots
Uploading three screenshots when the store allows ten means leaving persuasion capacity unused. Each slot is free real estate to answer an objection or show another benefit.
Fix: Fill the slots — up to 10 on the App Store, up to 8 per type on Google Play — with each image earning its place. Don't pad with filler, but don't stop at three if you have more to say.
11. Forgetting Google Play's feature graphic
The 1024×500 feature graphic is unique to Google Play and appears at the top of your listing and in promotional placements. Many makers who came from iOS skip it entirely and end up with a blank banner.
Fix: Design a dedicated feature graphic with your app name and a one-line value proposition. See our Google Play screenshot sizes guide for where it appears and how to size it.
How much do these mistakes actually cost you?
It's tempting to treat screenshots as a finishing touch, but they sit at the exact point where interest converts into installs. A person who searched a keyword, saw your icon, and tapped into your listing is already halfway to downloading — your screenshots either close that gap or reopen it.
Think of the fixes above in three tiers of impact:
| Tier |
Mistakes |
Consequence if ignored |
| Blocking |
Wrong dimensions, placeholder content, app mismatch |
Rejected on upload or in review |
| Conversion-killing |
Uncaptioned screens, buried message, unreadable text |
Lower tap-to-install rate |
| Reach-limiting |
No localization, unused slots, missing feature graphic |
Fewer installs from markets and placements you could win |
Fix the blocking tier first — those stop your app from shipping at all. Then work through the conversion tier, because that's where most of the download upside lives. The reach-limiting tier is your polish pass once the fundamentals are solid.
The encouraging part is that screenshots are one of the few listing elements you can change any time without shipping a new app build. That makes them ideal for iteration: publish your best set, watch how your conversion rate moves, then swap in new captions or a new lead image and compare. Unlike your app's code, there's no review-and-rebuild cycle for testing a new headline — so treat your screenshot set as a living asset, not a one-time deliverable.
A quick pre-upload checklist
Run this before you touch the upload button:
- [ ] Exported at exact store sizes (no manual resizing)
- [ ] First 2–3 images carry your strongest benefits
- [ ] Every image has a readable, benefit-focused caption
- [ ] Consistent background, font, and layout across the set
- [ ] Real content only — no placeholders or debug elements
- [ ] Legible at thumbnail size
- [ ] Localized captions for top non-English markets
- [ ] Screens match the current app version
- [ ] All available slots used well
- [ ] Google Play feature graphic (1024×500) created
Screenshots are the highest-leverage design work in your entire launch — a good set can lift your conversion rate meaningfully without changing a line of your app. If you want to compare the tools that make this easier, we've reviewed the best app store screenshot generators so you can pick the right one for your workflow.
Frequently asked questions
What is the most common app store screenshot mistake?
The most common mistake is uploading raw, uncaptioned device screenshots with no context. The store gives you the space to add a headline and visual framing to each image, and listings that use captions to explain the benefit almost always convert better than bare screens.
Why did the App Store reject my screenshots?
The usual reasons are wrong dimensions, placeholder or debug content, or screenshots that don't reflect the actual app. Apple requires exact sizes such as 1320×2868 for the iPhone 6.9-inch display, so export at the precise spec and show only real, final in-app content.
How many screenshots should I upload?
Upload all the slots the store allows — up to 10 on the App Store and up to 8 per type on Google Play — but make the first two or three carry your strongest messages. Most users decide from the first couple of images without swiping further.
