Screenshot upload is where a lot of launch energy gets wasted. The designs are done, but the files are the wrong size, the wrong locale, the wrong device slot, or the wrong version status.
Prepare by device target
Keep screenshot exports grouped by device target before opening App Store Connect. iPhone, iPad, and Mac requirements are different, and mixing files during upload is the fastest way to create mistakes.
Prepare by locale
A localized screenshot set should be complete before upload: same story, localized captions, matching order, and reviewed text. Do not upload half-localized assets just to “finish later”.
Check the first three screenshots first
Before bulk uploading, inspect the first three screenshots in every priority locale. They carry the conversion story. If they are weak, correct them before fighting upload mechanics.
Use a review checklist
Check text fit, device frame, status bar, pricing claims, outdated UI, spelling, legal copy, and whether the screenshot matches the current app version.
Record what changed
After upload, record the screenshot set, locale, date, and hypothesis. You need that history when conversion changes two weeks later.
Prepare sizes before upload
Organize screenshots by device, locale, and order before opening App Store Connect. Most upload mistakes come from mixing dimensions or old localized sets.
Check order and locale
The first three screenshots matter most. Verify that each locale has the right order, translated captions, readable text, and current product UI.
Keep a release record
Record which screenshot set changed, when it went live, and what metric should move. That makes post-release conversion analysis cleaner.
