It is possible to manually delete applications from an Amazon Kindle, but EduKindle recommends Clean Master Phone Boost to help in deleting unwanted applications. Clean Master is a highly rated app in the Amazon App Store. It is free and takes up very little space on the Kindle device.
In Amazon.com's product reviews, Clean Master is said to be efficient, practical and a great utility. The biggest criticism in the product reviews is that the app is known to put ads in the device status bar and that it can sometimes kill important applications that contain your phone applications. In spite of criticism, Clean Master has an overall rating of 4.5 stars from over 3,000 reviewers on the Amazon App Store.
