A clearer path to your next release

Start with the store requirements, check the files you actually exported, and finish with a review of the listing.

Fix an App Store screenshot size error

Diagnose a rejected screenshot by measuring pixels, checking its upload slot, orientation and alpha channel. Try reproducible passing and failing image files.

Your screenshot release checklist

Review device coverage, current app content, screenshot dimensions, image formats and the final exported files before updating your store listing.

How we maintain these guides

Apple and Google are the primary sources for their store requirements. Each guide records when those sources were checked. We distinguish file checks from store approval and avoid publishing unsupported product capabilities. Send a correction when a rule or example needs attention.
