Set up your app with iTunes Connect.
Once you've uploaded your app, you'll need a promotional plan to help people find your app. You can use several different methods to promote your app, such as using social media sites, creating a website, and more.

Submit your app to the App Store.
If you're ready to submit your app to the App store, you'll first need to register with iTunes Connect. This will allow you to manage your apps, set up pricing plans, and upload screenshots.

Promote your app.
Once you've registered with iTunes Connect, you'll need to add your app to the App Store. You can do this by uploading an.ipa file (the archive format used by iOS) to iTunes Connect.

Analyze your results.
It's easy to see what works and what doesn't when promoting apps. If you're not seeing any downloads, check your settings. Are you using the right keywords? Is your description optimized? Do you have enough reviews?
