In the year 2015, Amazon and Underground set up a platform in which users can download and use paid apps for free on FireTables and Android devices. Amazon paid the developers by the time an app was used. This stops the shipping giant.
In the concept of Amazon Underground Actually Free (“actually free”) there was also no in-app purchases, so the monetarization really only by the usage took place. At the same time, Underground registered when the app was paused, stopped, or restarted.
For Fire Tablets until 2019, for Android to Summer
On Android devices, Amazon ended the program for the summer of 2017. By 2019, however, the service would still be available for updates, but no new content should appear. Amazon takes only until May 31 new apps and games for the program. On Fire Tablets, Underground Actually Free can be used regularly until the complete setting 2019. Not affected is the Amazon Appstore, but only the Actually-Free program. Users who have downloaded and installed applications can access Android users during the summer. According to the Amazon, participating developers are to be paid according to the guidelines for the used time of their apps.
