Each rating is based on a scale of 1 to 5 stars and customers can choose to add a written review for iOS apps and Mac apps. The App Store defaults to showing ratings and reviews for an app's most recent version to ensure they reflect the experience customers will have when they download an app. Once your app has been reviewed, you can view, sort, and respond to reviews using iTunes Connect.
Asking Customers for Ratings and Reviews
You can ask your customers to rate and review your app on the App Store at appropriate times throughout the user experience. If you'd like to ask them to provide feedback on the App Store without leaving your app, you can use the SKStoreReviewController API. Simply choose when to prompt users to rate your app, for up to three prompts in a 365-day period. Customers will submit a rating through the standardized prompt, and can authenticate with Touch ID to write and submit a review. Learn best practices for asking customers for ratings and reviews, and get technical details on how to implement the SKStoreReviewController API.
Responding to Reviews on the App Store
Address user feedback directly on the App Store by responding to reviews. You can respond to all reviews of your app, no matter when they were written. When you reply to a review, the customer will be notified of your response and will have the option to update their review. You can edit your response at any time and only one response per review will display on your App Store product page. Get details on how responses work and learn how to craft a great response.
