App Store Connect

App Store Connect is Apple's developer portal for managing iOS, iPadOS, macOS, watchOS, tvOS, and visionOS apps. You upload binaries, set metadata, manage TestFlight, and run CPPs and PPO tests here.

App Store Connect is Apple's web portal at appstoreconnect.apple.com for managing apps across iOS, iPadOS, macOS, watchOS, tvOS, and visionOS. From here you upload builds (via Xcode, Transporter, or the App Store Connect API), edit metadata per localization, manage TestFlight for up to 10,000 external testers, configure in-app purchases and subscriptions, and run growth experiments through Custom Product Pages and Product Page Optimization. Media Manager holds up to 10 screenshots and 3 app previews per localization per device size, at exact pixel dimensions. App Analytics surfaces impressions, product-page views, conversion rate, and per-CPP performance. Team members hold roles (Admin, App Manager, Marketing, Developer, Finance) that gate access. Everything requires an active Apple Developer Program membership; there is no third-party route to write these fields, which makes App Store Connect the single source of truth for your listing.

Why It Matters

App Store Connect is the chokepoint for ASO: title, subtitle, the 100-character keyword field, screenshots, and every experiment live here, and no external tool can write them. It is also your source of truth for measurement. App Analytics separates impressions from product-page views and reports conversion rate per storefront and per Custom Product Page, the exact data that tells you whether a localized hero screenshot paid off. Master its localization matrix (one screenshot set × up to 40 languages × several device sizes) and you can ship a global update in one submission; misconfigure a device slot and Apple either rejects the build or serves a scaled, blurry asset to millions of users.

Example

An indie developer ships version 2.3. In App Store Connect they select the version, then fill the metadata matrix for 12 localizations. Writing a distinct 100-character keyword field for each of es-MX, de-DE, ja, and the rest. They open Media Manager and upload one 1320×2868 screenshot set for the iPhone 6.9" slot and one 2064×2752 set for the iPad 13" slot (M5 iPad Pro); Apple auto-scales those down to smaller devices. They attach a Custom Product Page for a Meta campaign, add a 22-second app preview, grant a contractor the Marketing role, and submit for review. App Analytics later shows the German page converting 4 points above baseline.

Frequently Asked Questions

Do I need App Store Connect access to do ASO?

Yes. App Store Connect is where you edit your title, subtitle, keyword field, screenshots, and run all optimization tests. There is no third-party way to change those fields. ASO tools can research and recommend, but the actual writes always happen inside App Store Connect.

How much does App Store Connect cost?

App Store Connect itself is free, but it requires an Apple Developer Program membership at $99/year for individuals and organizations. The separate $299/year Apple Developer Enterprise Program is only for distributing internal apps to your own employees. It cannot publish to the public App Store, so it is not what you want for ASO.

Can I upload screenshots from App Store Connect directly?

Yes. App Store Connect's Media Manager accepts PNG and JPG screenshots in RGB at exact device-specific dimensions, up to 10 per localization per device size. Tools like Shotlingo export ready-to-upload bundles at every required size so you avoid pixel-dimension rejections.

Which screenshot sizes does App Store Connect require in 2026?

Apple requires one iPhone 6.9" set (1320×2868 or 1290×2796) and one iPad 13" set (2064×2752 on the M4/M5 iPad Pro). Apple automatically scales those down to 6.5", 6.3", and smaller iPad classes, so you no longer upload every size, though you can override any slot with a purpose-built asset.

Can multiple people manage one app in App Store Connect?

Yes. Access is role-based: Admin, App Manager, Developer, Marketing, Finance, and more. You can give a translator or ASO contractor the Marketing role to edit metadata and screenshots without granting build-upload or financial access, and roles can be scoped per app so a freelancer only touches the app they work on.
