Is the App Store free?
In the App Store, if an app has a Get button instead of a price, the app is free. You won’t be charged for downloading a free app. Some free apps offer in-app purchases and subscriptions that you can buy. Subscriptions and in-app purchases give you access to more features, content, and more.
How much does Apple charge for App Store?
When you create a developer account with Apple, you are charged an annual app store fee of $99. New developers also assume that they will get 100% of the income from app sales, but this is not true. If you sell an app priced at $0.99, your share will be about $69.3. The rest of the money goes to the App Store.
