Apple has recently doubled the number of promo codes that developers receive per app release, according to multiple developers on Twitter. The company is now allowing 100 app download codes to be generated with each app update instead of 50, giving developers more codes to share with friends, family, and press.
Each time a developer releases a new app or an app update, they can generate promotional codes that allow users to download an app ahead of release. Generally these codes are provided to press for reviews, and when the generated codes are used up, no additional codes can be obtained until the app is updated.
With an extra 50 codes to go around, developers will have more freedom and flexibility when promoting their apps in the future. While Apple has yet to confirm the promo code increase, developers are already seeing the additional codes in iTunes Connect.
