Best Practices
Proven techniques to increase App Store conversion rates.
Your first screenshot is your most powerful. Show the core benefit, not a login screen or empty state. Users scan app listings in seconds.

Text overlays turn screenshots into mini advertisements. Use 3–6 words of benefit-focused copy above or below the device mockup.
Do
Don't
Design your screenshots as a sequence. Screenshot 1 hooks attention, screenshots 2–4 show depth, the final screenshot closes with social proof.
Do
Don't
Background colors communicate category and tone. Dark gradients signal premium; bright gradients signal consumer/lifestyle apps.
Do
Don't
Use the latest hardware (iPhone 15/16, Pixel 8, Galaxy S24) rather than dated frames. Mismatched hardware can make an app look unmaintained.

App Store Connect allows separate screenshots per locale. Localized screenshots for top markets (DE, JP, KR) can increase conversion by 20–40%.

Integration
How to upload your screenshots to each platform store.
App Store Connect rejects screenshots with transparency (alpha channel). Export as PNG without alpha or as JPEG.
Google Play uses the first screenshot as the thumbnail in search. Make sure it works standalone without surrounding context.
Windows Store screenshots render at multiple sizes. Use simple layouts that read clearly at thumbnail scale.
