If you’re familiar with Swearch, a neat iPhone web app that allows you to search for a specific query on multiple websites at once, then you’re most definitely going to be interested in Search Ninja, a $0.99 app that allows you to flick through search engines, star search results, and start typing in seconds to find exactly what you’re looking for. Search Ninja’s concept is simple, but the execution is powerful in the way it meets a user’s expectations when it comes to mobile search. Upon opening the app, you’re immediately greeted with a Google search field, and the iOS keyboard ready to type. No need to tap on buttons to start searching, no need to do anything before performing a regular Google Search. If you, however, want to customize the search experience and have those extra seconds to make sure you’re navigating to the right webpages, Search Ninja features an intuitive swipe interface to switch between search engines in seconds. Both on the main screen and in the embedded web view, you can swipe to change from Google to Bing, Twitter, Wikipedia, IMDB, Youtube, Flickr and many, many more. You can even add other engines if you really feel like your favorite one is missing, although the process requires a 2-step wizard screen.

Two features I particularly appreciate about Search Ninja are favorite searches and the History section. They’re very straightforward, but come in handy if you find yourself looking for the same things on your iPhone over and over, or simply want to look up an old subject again.

Search Ninja strikes me for its simplicity and clean design. Gestures to switch engines are a plus, and a very useful one. Get the app here at $0.99.
