Apple appears to be allowing developers to create promo codes for in-app purchases, a useful feature that makes it far easier to test and promote freemium games and apps with content that can only be purchased within an app once it has been downloaded. Promo codes for apps have long been available, but were previously limited to initial app downloads and were not available for in-app purchases. This change will make it easier for developers to give early app testers, reviewers, and other users access to the full content available within freemium apps. While it is unclear if the feature is currently available to all developers, Jeff Scott of 148apps.com shared a screenshot on Twitter of an in-app purchase promo code for Real Racing 3, from major developer EA. EA is using the promotion to give customers 10 free gold within the app, which has an in-app value of $1.99.
