App stores best practices

Learn about the best practices when submitting an app to the app stores.

This guide offers best practices for submitting your app to the app stores. To learn how to generate native binaries for submission, see Create your first build.

Disclaimer: Review guidelines and rules are updated frequently, and enforcement of various rules can sometimes be inconsistent. There is no guarantee that your particular project will be accepted by either platform, and you are ultimately responsible for your app's behavior. That said, you can re-submit your app as needed to address feedback from reviews.

Apple: Review guidelines

Official Apple guide on preparing your app for App Store review.

Responsive design

It's a good idea to test your app on a device or simulator with a small screen (for example, an iPhone SE) and a large screen (for example, an iPhone X). Ensure your components render the way you expect, no buttons are blocked, and all text fields are accessible.

Try your app on tablets in addition to handsets. Even if you have ios.supportsTablet: false configured, your app will still render at phone resolution on iPads and must be usable.

Apple may reject your app if elements don't render properly on an iPad, even if your app doesn't target the iPad form factor. Be sure and test your app on an iPad (or iPad simulator).

Privacy policy

Starting October 3, 2018, all new iOS apps and app updates will be required to have a privacy policy to pass the App Store Review Guidelines.

App privacy questions

Beginning December 8, 2020, new app submissions and updates are required to provide information about their privacy practices in App Store Connect. See App privacy details on the App Store for more information.

Apple will ask you a series of questions when you submit the app. Depending on which libraries you use, your answers may vary. For example, if you use expo-updates, you will need to say Yes, we collect data from this app and then you will want to select Crash Data.
