I'm a huge fan of SwiftKey, and use it on every Android device I own - it is the first app I install when I get a new Android-based device, and because typing is one of the most important things you'll do on a smart device, it's also one of the most important.

SwiftKey 3 is on special at the moment as part of Google's celebration of hitting 25 billion downloads on their Google Play store. SwiftKey 3 has dropped from $3.99 to just $0.99 - a 75% discount! If you haven't tried SwiftKey and want to get into it, at this price you'd be crazy not to. Here's what SwiftKey 3 offers:

• Smart Space - adding to SwiftKey's already cutting edge correction, Smart Space detects mistyped or omitted spaces across strings of sloppily typed words in real-time.
• Two new themes - a new theme, 'Cobalt', to match SwiftKey's new look and feel, and an Ice Cream Sandwich-styled 'Holo' theme, as voted for by SwiftKey's VIP community.
• An enhanced UI - a much larger space bar and smart punctuation key help improve accuracy and make it quick and easy to access common punctuation. Just tap and slide left on the period for exclamation point, or tap and slide right for question mark. No need to long-press.
• Additional languages - SwiftKey 3 now offers support for an additional seven languages, bringing the total up to 42. The new languages are Korean, Estonian, Farsi, Icelandic, Latvian, Lithuanian and Serbian. And of course, you can still enable up to three at once.

You can grab SwiftKey 3 from the Google Play store on your device, or here.
