A feature that has been in Google Play’s Store for a while now is making its way to the Amazon Appstore, as developers now have the ability to integrate in-app purchases into their apps.
In-app payments can be in the form of additional features or subscriptions, as well as bonuses and upgrades for games.
Why is this important when it’s already available for Google Play apps you may ask? For one, it offers developers the ability to target users with custom Android devices able to use only the Amazon Appstore as their app market, such as the Kindle Fire. It also offers the same for Android devices not approved by Google to access the Play Store.
