✅ Done. App delivery, AppCenter-style — minus the lock-in.

3/ 📄 iOS needs a manifest.plist that points to your .ipa — generate it via Fastlane using bundleId, version, and url path.

4/ 🎯 Build a small front-end with 2 download buttons:
- Android: direct .apk link
- iOS: opens itms-services://?action=download-manifest&url=<your_plist_url>

2/ 🚀 Use Fastlane to upload your builds (no EAS here — you’re in charge)

Too lazy to dive into Ruby? Same. Here’s the hack: use sh to run shell and just use curl

def upload(build_path, url)
sh("curl -X PUT -T '#{build_path}' '#{url}'")
end
