10 App Store screenshot mistakes killing your downloads
The most common screenshot mistakes we see in indie apps — from unreadable captions to fake device frames — and the fix for each one.
After roasting a lot of indie App Store pages, the same problems come up again and again. None of them are exotic. Most take an afternoon to fix. Here are the ten that cost the most downloads, roughly in order of damage.
1. Raw screenshots with no captions
A naked UI screenshot asks the viewer to figure out what your app does, why it's good, and why they should care — all from a screen they've never seen. Nobody does that work. Every screenshot needs a short benefit-led headline. (Full guide: screenshot copywriting.)
2. Text too small to read at thumbnail size
Screenshots are judged in search results at roughly one-third scale. Body-size caption text disappears completely at that size.
3. Burying the best screenshot at position 5
Apple shows three screenshots in search results, the third partially cropped. Your strongest visual and strongest claim must be screenshot #1 — not the finale of a story nobody scrolls to.
4. Splash screens, logos, and empty states
Screenshot #1 showing your logo on a gradient tells the user nothing your icon didn't already say. Empty states ("No tasks yet!") are even worse — they make the app look dead. Fill every screen with realistic, appealing data.
5. One screen, ten angles
Ten screenshots of the same list view with different filters selected is one screenshot's worth of information. Each frame should answer a new question: What does it do? How? What else? Why you?
6. Clutter — three messages per frame

Before
Your notes, everywhere
After
When a screenshot makes three claims, the reader retains zero. One headline, one visual focal point, one idea per frame — the discipline that separates professional pages from hobby ones.
7. Wrong or stretched dimensions
Designing at 9:16 and stretching to Apple's 1:2.168 ratio distorts the UI; letterboxing wastes a fifth of the frame. Design at exact App Store dimensions from the start — 1320×2868 or 1290×2796 for iPhone, 1280×800 minimum for Mac.
8. Fake UI that will get you rejected — or uninstalled
Screenshots showing features that don't exist violate App Review Guideline 2.3 and, when they slip through, generate one-star "not what was advertised" reviews. Polish reality; don't fabricate it. (More on this in our rejection guide.)
9. Ignoring dark mode contrast
A white-background screenshot set looks fine on the store's light theme and blinding next to competitors when the user browses in dark mode — and vice versa. Whatever palette you choose, check the contrast between your caption text and its background; low-contrast grey-on-grey is the most common legibility killer we see.
10. English-only screenshots in every storefront
If your app is available in Japan, German-speaking markets, or Latin America, English screenshots are silently costing conversions there. Translating just the caption text — while keeping the design identical — is one of the highest-ROI ASO moves available. Not sure where to start? See which languages to localize first.
The quick self-audit
Do
- Benefit-led caption on every screenshot
- Strongest message in frame #1, top half of the canvas
- Legible at one-third scale (squint test)
- Exact Apple dimensions, no stretching
- Localized captions in your top storefronts
Don't
- Splash screens, logos, or empty states
- More than one idea per frame
- Body text you can't read in search results
- Features in screenshots that don't exist in the app
- Same screen repeated with minor variations
Fix them in one pass
Every mistake on this list is visible from the outside — which means an outside critique catches all ten at once. Upload your screenshots to Screenshot Roast and it will score them, name which of these mistakes you're making, and redesign the frames for you at exact App Store dimensions. The before/after gallery shows what the fixes look like on real apps.
