A specific term that refers to Amazon's online store for purchasing and downloading software applications and mobile apps for the company’s Kindle line of e-book readers as well as other Android-powered devices. The "appstore" name used by Amazon has led to legal action by Apple for its similarity to the company's own App Store, and it's also frequently confused with the more generic "app store" term that’s used to represent the market of emerging app stores such as Apple’s App Store for its iOS-powered devices, the Android Market for Android devices, Blackberry’s App World for Blackberry devices and Nokia's Ovi Store.
Similar to Apple's App Store, developers can submit their free or paid apps for inclusion on the Amazon Appstore, with developers of paid apps receiving either 70 percent of the sales price or 20 percent of the developer’s list price. The Amazon Appstore also features a "free app a day" program in which one paid app is offered for free for one day only.
