App submission (and updating an existing app) is done through your iTunes Connect account. Before logging on, look at a few apps in the App Store to see how these items are placed in the store. Before you submit your application binary, be sure to Prepare your app for submission to the iTunes Store.
- Once your app is ready to submit, use the Application Loader to upload the app binary. You get the application loader from the Download Application Loader link at the bottom of the iTunesConnect's Manage Your Apps page.
