Search app Taptu has just launched a version for Android. You'll be able to use Taptu to search the web for touch-screen friendly sites, with content deliver in realtime through OneRiot's API.
Content is optimised for Android screens and browsers, so you'll receive things that are perfectly sized. For now, it's just a search box, but additional capabilities such as sharing onto Twitter and Facebook and market app searching will be available in the next version along with improved app functionality.
Taptu already has versions for iPhone (of course) and non-touch phones, where it'll search for mini-sized content perfect for the regular Joe phone.
