In this model, users pay once to download your app and use all of its functionality. There are no additional charges. The paid model resonates with users who prefer to pay once to get the full app experience, without in-app purchases.
Because the cost to download may make users consider the app’s value more carefully, successful paid apps are often positioned as premium experiences through outstanding design, functionality, and marketing.
Since paid apps have only one point of monetization, marketing plays an even more important role in acquiring users. Successful developers make sure that their app’s title, icon, description, preview, screenshots, and other marketing communications effectively showcase the premium nature of the app.
If you have multiple paid iOS apps, you can leverage app bundles, which make it easy for users to buy up to 10 of your apps in a single purchase at a reduced price.
