An app purchase refers to buying a mobile or desktop application or making in-app transactions within an app. This could include paying for a premium version, unlocking features, removing ads, or purchasing virtual goods in a game. App purchases can be one-time payments or subscriptions that grant ongoing access to content or services. There are different types of app purchases, including paid apps, where you pay upfront to download, in-app purchases (IAPs) for digital goods or upgrades, and subscriptions for recurring premium access. Always check the app's pricing details before purchasing. Have you made an app purchase recently? Share your experience!
