User:Vipul/Amazon Underground

Amazon Underground is an Android app offered by Amazon through which people can freely download and obtain in-app items that they would otherwise have to pay money to purchase. Amazon has used the catchphrase "Actually Free" to describe the policy, and affirmed that Amazon Underground is not a one-time or temporary offer but is here to stay. Participation by app developers in the program is voluntary. Amazon compensates app developers based on the time that users spend within the app, at a flat rate of $0.002 per user minute.

For consumers
Consumers interested in using Amazon Underground can download the app from the Amazon website. The app cannot be downloaded from Google Play, Google's Android app store, since it violates the conditions necessary to be listed in the app store.

Once the consumer has downloaded Amazon Underground, he or she can download all apps participating in Amazon Underground from within the Amazon Underground app. In addition to being able to download the app for free, the consumer can also make "in-app purchases" for free.

For app creators
An app creator can choose to participate in the Amazon Underground program. The app creator receives payment based on the time spent by users in the app after downloading it, at a flat rate of $0.002 per user minute in the app.

Amazon has listed the following eligibility requirements for participating apps:


 * The app must be available for download from the Google Play or Apple App Store, and be monetized in at least one of the following ways:
 * The app is available to purchase for a fee in all other app stores where it is sold
 * The app contains in-app items that are available for purchase for a fee.
 * The app must not contain any subscription in-app items.
 * The features and gameplay of the Amazon Underground version must ve substantially similar to or better than the non-Underground version.
 * When submitted to the Amazon Appstore, the app must be made available on at east one non-Amazon mobile device.

Amazon Underground is a good fit for freemium or premium apps, but Amazon advises against using it for the following apps:


 * Apps that run continuously in the background
 * Apps that are completely free (freely available, no in-app purchases)
 * Apps that are monetized through ads
 * Apps that support streaming, such as radio apps
 * Apps containing subscription services

In addition, Underground is not recommended for modified version of an app that have removed in-app purchases, or that have modified their gameplay by removing in-game currency, or premium apps whose only premium feature is being ad-free.

Monetization by Amazon
Amazon pays app creators based on the total time spent by users in the app. In order to monetize Amazon Underground, Amazon shows ads when somebody first downloads an app, and occasionally on each subsequent opening of the app.

History
Amazon Underground launched on August 26, 2015, and simultaneously retired its daily free app program.

In March 2016, Amazon reported some statistics on the growth of Amazon Underground, leading to renewed media coverage of Amazon Underground.

Reception
Amazon Underground has been critiqued for being much smaller than the Google Play app store, making it of limited utility as a standalone source for getting games.

The goat simulator app has performed well on Amazon Underground, leading Wired writer Brian Barrett to argue that the lack of need for payment may make the app particularly appealing to children, for whom even a small amount of money requires parental consent.

On the other hand, Amazon Underground has been praised for helping developers focus on creating engaging in-app experiences rather than worrying about monetizing through in-app purchases. It has also been praised for helping all developers make money right off the bat in direct proportion to usage, compared to the in-app purchase model that only some kinds of apps could make significant money off of. Commentators have compared it to the Kindle Unlimited plan where Amazon allows readers to read books for free from a diverse collection of authors and then pays authors based on the fraction of their books read.

A report by IHS Technology highlighted the following key challenges for Amazon Underground:


 * The challenge of user acquisition, in a world where many apps were free for initial download and monetized through in-app purchases
 * Economics that would not fit the needs of all apps
 * Strong app store competition, and the fact that Amazon Underground does not come pre-installed on any non-Amazon devices (the bulk of smartphones and tablets)
