The purpose of this web app was to group links based on a basecamp project. The app is utilized internally to have people test out the links on their mobile devices. We used to use http://sitetophone.com/ to upload a link and share it. This became a pain because you had to login and then find all the links you wanted.
There is also a add project page where someone would add a new set of links. I have provided a demo link below.
