What does an app purchase mean? Regarding the app payment, the decision-making process involves paying for a mobile application with other commodities such as digital products, services, or information. This is different from simply obtaining the application from the app store since you pay for credits to obtain the application. IAPs allow consumers to download additional features to the digital goods or pay for subscriptions to the paid application without shifting to the application store.
