Your app is built. It is not in the stores. That last mile is its own job: certificates and signing, provisioning profiles, bundle IDs, screenshots at the right sizes, privacy nutrition labels, data safety forms, age ratings, export compliance, and a review team that will send it back for any of them.

I have taken 8 apps through this under my own company's Apple and Google developer accounts, including rejections and appeals. I do it on your accounts so you own everything at the end.

What you get: signed release builds for iOS and Android, complete store listings, both submissions filed, and the replies to App Review handled if they push back. Los Angeles, California.
