From the developer:
SimpleURL is an easy-to-use application that helps you shorten more or less long URLs. All you need to do is enter the original URL and enable the shortening operation. The newly generated short URL is automatically copied so you can paste it instantly. However, you have the history of the latest shortened URL so you can copy manually previously generated URLs anytime you want.
