The ability to test out apps from the Amazon's mobile AppStore is no more, according to TechCrunch.
Amazon mobile product users used to be able to test out apps in their mobile browser before purchasing through a program called TestDrive, which rolled out in 2011. However, the online retail giant killed the program on April 15, 2015, citing a few issues.
There were only 16,000 apps in the store which fell under the TestDrive feature umbrella, so it seems as if though an interesting idea, it never really gained traction. TechCrunch speculates that this may be because most of the apps that featured TestDrive were free game apps, so people were just downloading them right away instead of testing them first.
The Amazon AppStore supports apps for the Amazon Fire devices. Here's more on the Amazon AppStore from PC World:
The Amazon Appstore is the retailer giant's effort at getting developers to go through its own marketplace. While it serves as the app storefront for its Fire devices, you can side-load the store on to your own Android device. Amazon frequently runs fire sales to attract new users by giving away paid apps.
TechCrunch also reports that Amazon has been working on "Amazon Unlocked," an Amazon Prime for apps in which the user pays a flat rate and is able to download apps (and unlock in-app purchases) under that one flat rate umbrella.
