Bing

PCMag proclaimed Bing for iPhone "the best general search app" in the iTunes App Store when it debuted in 2009. Since then, Microsoft has expanded the functionality of its Bing app to include voice, barcode, and photo-based search to give users a variety of ways to gather information. The iPhone app sports a simple yet elegant black-and-white interface, highlighted by a large wallpaper image. The Vision Search feature needs more time to mature, but Bing delivers consistently good search results on the iPhone.
