Amazon today introduced a new app called "Amazon App: Browse, Search, and Shop," which is designed to let users look for and purchase items from Amazon.com.Anyone can use Amazon's new app to browse through and search for products using dictation, but to make a purchase, an Amazon Prime membership is required. Amazon Prime costs $99 per year and offers benefits like Amazon Video and free two-day shipping.Amazon App includes product details, reviews, and "immersive" product images and videos, all of which can be viewed on the television screen. Purchases are made using the Apple TV remote, but users can also add items to a list to purchase later via an iPhone or computer.Many Apple TV owners have long been hoping for an app that brings Amazon's Prime Video offerings to Apple's set-top box, but this is not that app. It's limited to shopping only.Amazon's new app can be downloaded on fourth-generation Apple TV models for free.
