Android: DuckDuckGo's mobile app makes the fast-answering, minimalist search engine easily accessible on the go.
There's a lot to like about previously mentioned DuckDuckGo, and there's even more to like about its mobile app. For starters, the app has all the functionality of the full site, but it actually seems more fitting when used on a mobile device.
The "zero-click info" feature of DuckDuckGo suddenly becomes a major star, since looking up quick questions while out and about is when you really want things boiled down to a minimum. That's where the app excels; less than a second after you enter a search term, DuckDuckGo loads a quick bit of essential information about whatever it is you entered. If you entered something vague, then it comes up with a quick list of possible searches that you meant. One click and the info that's most likely to help you is on the screen — it's that simple.
As a search engine, DuckDuckGo has some great positive features. There's no user-tracking (it seems to be a point of pride, to the point that the mobile app even has built-in support for Tor), "useless" sites that most people deem as spam are quickly banned from search results, and there are loads of special searches and syntax tricks that help users get where they're going even faster.
For example, typing !amazon pillow will immediately route the user to an Amazon search page for pillows. The same trick would work for just about any site.
A feature present in the mobile app that you won't find in a browser is voice search, which has the potential to really speed up answer-finding when combined with the app's zero-click info feature. Users can also set a custom search widget by using the Google Search widget and setting it to use DuckDuckGo instead.
DuckDuckGo is a free app for devices running Android versions 1.6 or newer, and is available at the Android Market.
