In fact, a number of users specifically user the Amazon Appstore for specific features which are unique to Amazon's offering. Probably, the most obvious one is Amazon's Free App Of The Day (FOTD) promotion. For those, who have still not used this, in short, Amazon offers their users a premium (paid) app for free, every day. The app changes each day and costs nothing to download during that twenty four hour period. Not to mention, they are often giving away a ton of apps in their regular free app bundles. Another interesting feature which Amazon launched back in 2011 was the 'Test Drive' feature. This allowed users to effectively try an app before they buy the app. The Test Drive option utilized the browser to show how an app looks, performs and its content, offering users a quick peek before handing over their money.
