Amazon Underground for Android is a supplement to Amazon's own Appstore. It allows users to download apps and games for free that would otherwise cost money up-front, and it allows users to benefit from free microtransactions (such as getting free in-game items) in other games.
Amazon Underground is free, and the apps provided on it are also free to Prime users. Other users may not find Amazon Underground to be as valuable, as it is tied into the Prime service.
To download Amazon Underground for Android, you must first enable Unknown sources. To do this, you must open the Android Settings menu and navigate to Security. From there, check the box that allows you to install apps from unknown sources, and confirm that you wish to do so. This will allow installation of Amazon Underground.
For developers, Amazon Underground pays based on time spent using the app by users of the Underground marketplace. For end users, the "catch" is that you'll occasionally see an ad when you launch an app, and Amazon will collect your usage data to pay developers and potentially for other purposes.
The service is safe to use and the apps available from Underground are reviewed by Amazon. However, those concerned about security and privacy may wish to protect themselves more carefully, or avoid using the Underground marketplace. Amazon's Appstore is a good alternative.
To track the app's data usage, open Amazon Underground and open the Menu. Under Apps & Games Settings, you can find the option to track data usage and check it off. Android also provides some data tracking of its own, but this may not be as complete.
You can update Amazon Underground manually or automatically through Android, as with other apps. You can also update Amazon Underground through Amazon's website. There is also a setting available under Your Apps And Devices that will allow you to automatically update Underground whenever it is modified.

As of this writing, Amazon Underground is slated to continue running until some time in 2019. Users with existing apps downloaded from the store can use them freely, and developers are still paid for the usage of their apps.
Amazon Underground can be removed in the same way as any other app. You may also delete it from Amazon.com by logging into your account, going to Your Apps And Devices, then to Your Apps, and deleting it from this menu.
