Shipping on both stores? The preview video, screenshot, and feature-graphic rules differ in ways that trip up cross-platform developers. Here is what changes between them.
If you ship on both iOS and Android, you cannot just reuse the same assets. Apple and Google have meaningfully different rules for previews, screenshots, and store graphics. Here is what to adjust when porting your store presence across.
Preview video: hosted vs. uploaded
The biggest difference: Apple hosts your preview directly (you upload the video file to App Store Connect), while Google Play uses a YouTube link for its promo video. That changes your whole workflow: for Play you publish to YouTube and paste the URL; for the App Store you export a file at an exact resolution.
- App Store: upload a 15–30 second video at exact device resolution; autoplays muted at the top of the page.
- Google Play: link a YouTube video; it appears with a play button over your feature graphic, and viewers tap to watch.
- Apple's preview must show only your app; Google's promo video allows more marketing-style content.
Screenshots: count and shape
- App Store: up to 10 screenshots per device size, at exact required resolutions.
- Google Play: 2 to 8 phone screenshots, with more flexible dimensions and aspect ratios.
- Both reward captioned, benefit-led screenshots over raw captures.
The feature graphic is Play-only
Google Play requires a feature graphic: a 1024 × 500 banner shown atop your listing and used in promotions. The App Store has no direct equivalent. If you are coming from iOS, this is a net-new asset you will need to design.
Poster frames and autoplay
Apple's autoplay-muted behavior means your opening seconds and poster frame are critical. Google's tap-to-play model means your feature graphic and the video thumbnail do more of the early persuading. Optimize the right asset for the right behavior on each store.
Treat the two stores as two audiences with two habits, not one listing copied twice.

prevy is built around Apple's exact preview spec, so the iOS side is handled to the pixel, and the same clean export gives you a strong base to repurpose into a YouTube cut for Google Play.
