The free Bing app also features location awareness, maps, directions and voice search. It also features Bing’s image of the day from the website.
The Bing iPhone app builds on existing BlackBerry and Windows apps, as well a mobile website as Microsoft increases its presence on the platform.
Writing on the Bing blog, Justin Jed, group product manager for Bing Mobile, said, “Our investments in voice search continue in our iPhone App and works great for map locations as well as old-fashioned web search.”
Rivals Google and Yahoo have launched a range of iPhone apps around both search and services.
The launch comes as Bing exceeded 10% market share in the US for the first time since Microsoft’s search engine was relaunched.
Bing hit 10.3% of US market share in November, up 0.4% month on month, closing in on second placed Yahoo, which dropped by 0.5% to 17.5% market share.
However, both remain significantly behind Google which increased by 0.2% on October to 65.6%.
