Helm is a native App Store Connect companion built for developers who ship often. Manage versions, metadata, screenshots, TestFlight, subscriptions, reviews, in-app events, and editorial nominations from one fast interface so everyday listing work stays out of your way. ■ LISTINGS THAT KEEP UP WITH YOUR RELEASES Edit app updates across platforms, tune promotional text and release notes, manage phased releases, and submit for App Review when everything checks out. Open App Store Connect in the browser anytime you still need it. ■ METADATA, LOCALIZATION, AND AI Improve descriptions, explore keywords, and translate listing fields and in-app event copy across locales with tools meant for real submissions, not generic prompts. ■ APP STORE OPTIMIZATION Catch duplicate keywords, review practical guidance, and preview how your listing appears in search results so it reads cleanly before you submit. ■ SCREENSHOTS AND PREVIEWS Reorder and replace assets while Helm handles sizing, alpha cleanup, visionOS simulator workflows, and Magic Upload so files land in the right locale and order. ■ APP INFORMATION AND REVIEW CONTACTS Maintain app-level details and App Review Information, with shortcuts to reuse trusted contact data when Apple needs to reach you. ■ TESTFLIGHT Draft beta release notes, invite internal and external testers and groups, pull contacts when you want speed, submit builds for beta review, and stay on top of feedback. ■ CUSTOMER REVIEWS Filter and sort reviews, reply with templates, translate replies when it helps, export what you need, and copy your App Store review link quickly. ■ IN-APP PURCHASES AND SUBSCRIPTIONS Create and organize products, manage subscription groups and pricing, and handle promotional pricing, offer codes, and win-back offers where available. ■ IN-APP EVENTS Create and duplicate events, localize event copy, and submit them as part of your release workflow. ■ APP STORE NOMINATIONS Track drafts, upcoming, and past editorial nominations so that promoting your app to the App Store team stays organized. ■ ACCESSIBILITY Fill and monitor App Store accessibility nutrition labels so your product page reflects the experience you ship. ■ HELM PASSPORT AND WIDGET Collect developer contacts like stamps, share yours with a QR code or widget, and invite people into TestFlight builds or groups. An App Clip gets new contacts started in seconds when they are not on Helm yet. ■ ACCOUNT FLEXIBILITY Sign in with App Store Connect API keys, keep multiple Helm setups for separate developer accounts, and use Helm setup files to onboard or move configuration between devices. ■ STAY IN THE LOOP Optional notifications for builds, version changes, and TestFlight feedback so important updates do not get lost.
