Here's the description from the App Store:
Jolicloud is a service designed to facilitate access to all your online content. Jolicloud indexes everything you created, liked or received on the popular online services you use: Facebook, Twitter, Picasa, Flickr, Instagram and more.
Jolicloud builds automatically a personal and searchable library with all your photos, videos, music, documents, and links. No more tiny URLs or obscure links, Jolicloud shows you the content the way it was meant to be seen. Access all the moments of your life captured from your digital trail. You can also create collections to sort important content or memories.
Explore and search your personal cloud like never before. Your Jolicloud is entirely searchable so you can find a document you shared on your Facebook wall a year ago or a Twitter link you absolutely need for a presentation.
It's their first release and most of the users like it. Why don't you try it? I will try mine after posting this one :)
