Google Play Supporting Promo Codes For Apps, Games

Google is enabling support for redeemable promo codes for apps and games in its Google Play Store.
The ability to add promo codes is a longtime feature of the Apple App Store, but it had never been introduced for Google Play.
Now, reported 9to5 Google, app developers have the option to include them through the Google Play Developer Console.
The news is good for developers, who can use the codes to give away free copies of their paid apps as part of promotions or user reviews.
Codes can be used to unlock special features within an app or give away "friends and family" discounts to business employees.
