History Search

This is the most unique and useful web-app i have ever seen,
Everyday we browse through many web pages and bookmark those whom we find helpful and would like to visit again.
but there comes a point when there are so many bookmarks that u don't actually remember that which required information was on which webpage
This is when History search app comes into action.

Cons: there is no Mobile Application yet

Verdict: Why dig through the same Google result over and over again to find something when History Search can search through pages you actually visited and give you the search results you need.
