The latest version (4.0) delivers speed enhancements, external keyboard support, freeze panes and sort in Excel, multitasking and retina display support.
Nuance's Dragon Dictation is a free speech-to-text app that, the company claims, is up to five times faster than typing on the iPhone's on-screen keyboard. Once your text is dictated and edited (using the voice-driven correction interface), you can send it by email or SMS, copy and paste into other applications — or even deliver it straight to Facebook or Twitter.
