Amazon has ended their long running “Free App of the Day” promotion which offered a different free paid app every day through their Amazon Appstore for Android. In its place, Amazon has introduced Amazon Underground which claims to offer “over $10,000 in apps, games and in-app items that are actually free.” A new Underground Apps section has been added to the Amazon Appstore which currently includes 471 paid apps which you can get for free. Additinaly, Amazon has rebranded their shopping app in their own appstore into the Amazon Underground App which, according to the updated description, “includes enhanced features that aren’t available on the Amazon Shopping app found on Google Play.”
Unlike the old Free App of the Day promotion, these Amazon Underground free apps are listed separately from their paid counterparts. Searching for apps in the Amazon Appstore will bring up two listings for the same app if the app is offered in the underground section. For example, Castle of Illusion can still be purchased for its regular price of $9.99 even though there is a free version in the underground section. The underground app listings appear to have tighter restrictions on which devices they can be installed on. Castle of Illusion is a Fire TV compatible app, yet the free version cannot be installed on the Fire TV.
More information about Amazon Underground has been revealed. The reason there are separate underground app listings is because Amazon is introducing a new business model with these underground apps. They are free to you forever, but Amazon will be paying developers a certain amount on a per-minute played basis. This means, unlike with the Free App of the Day program, developers will actually be reimbursed by Amazon for including their apps in this program. Additionally, all Amazon Underground apps are completely free with no in-app purchases. Amazon says this is a long-term program, rather than a one-off promotion, which they will continue to introduce more benefits into.
