Apple has announced to developers that they are changing the in-app purchase feature of App Store applications. In the past, only paid applications could use the in-app purchase feature however, Apple is now allowing the feature to be implemented into free apps as well as paid apps.

I’m not sure what I think about this yet but, I do think it could help clean up the App Store a bit. Instead of developers creating a free lite version of their app, they could just make the application free with an in-app purchase to buy the full game thus eliminating the need for free lite versions of applications.

Below is Apple’s memo.

In App Purchase is being rapidly adopted by developers in their paid apps. Now you can use In App Purchase in your free apps to sell content, subscriptions, and digital services.

You can also simplify your development by creating a single version of your app that uses In App Purchase to unlock additional functionality, eliminating the need to create Lite versions of your app. Using In App Purchase in your app can also help combat some of the problems of software piracy by allowing you to verify In App Purchases.
