TipToe was created to make web search easier while on the go. Instead of using the built-in search of Safari, you can just search the web from TipToe, with a few advantages: it should remove all aggregated results of server farms, and the interface is free of ads. The web browser lets you go through the list of results quickly and efficiently. One more point: TipToe does NOT track your searches, and respects your privacy.
This app also offers the possibility to export your search results - the links through email, copy, or open in Safari... and it sends to your favorite social networks (Twitter, Facebook) or bookmarks to Instapaper, ReadItLater, and Pinboard.
