The app from Microsoft’s search engine is available free-of-charge, and it supports voice search and features the Bing image of the day on its home screen.
From Bing for Mobile’s Justin Jed’s post on the Bing Search Blog:
Let’s talk about some cool stuff you can do with the Bing App. Our investments in voice search (you may have played with them on Windows phones or BlackBerry already) continues in our iPhone App and works great for map locations, as well as old fashioned Web search. Just say, “San Francisco weather,” for a quick result, or even say a full address for a map or directions. Try something complex, like, “1 Microsoft Way, Redmond 98052.” (Yes, I know how to get to work.) Hold the phone to your ear and speak, or press the mic button—simple.
Speaking of directions (ha), looking for a coffee shop nearby? Bing automatically finds your location. It’s also easy to discover a new spot by category such as restaurants, banks, theaters and choose whether you want walking or driving directions.
We’ve got smooth mapping action. Swipe through each step of the directions, and check out how fast the map pans and zooms. (Techies take note: We use Seadragon technology for some of this.) For times when you only have one hand free and can’t pinch, there is a handy zoom-out button.
