TouchType has launched SwiftKey X for Android smartphones and SwiftKey Tablet X for Android tablets. The launch builds on the company’s success with its original Android keyboard app SwiftKey, which debuted one year ago and has since clocked up more than 1.5m downloads.

SwiftKey X and SwiftKey Tablet X both feature the Fluency 2.0 language inference engine, which TouchType describes as: “the latest evolution in artificial intelligence-driven text entry”. Fluency 2.0 uses machine learning to predict and correct by observing how a user composes text, and then predicting what they are most likely to type next.

The apps also offer cloud learning from the user’s message history on Gmail, Twitter and Facebook to offer a custom-fit prediction and correction experience. They also offer ‘Touch Interaction Modeling’ integration. This conducts real-time analysis of the user’s touchscreen typing precision to improve word accuracy and predictions.
The apps also offer keyboard themes and new customizations; the option to choose from more than 20 languages, and to type in up to three languages at once, with auto-correction that is language-aware; plus an improved settings and installer user interface.

In addition, SwiftKey Tablet X incorporates an innovative split-key layout for thumb typing on the larger touchscreen tablet form factor. The concept, developed by TouchType ahead of a showcase at Google’s Honeycomb launch in February, has already been recognized for its innovative approach with a CTIA Emerging Technology award.

“Our new apps for smartphone and tablet give consumers direct access to the world’s most advanced language technology of its kind,” says TouchType co-founder and CEO, Jon Reynolds. “We’ve built SwiftKey X and SwiftKey Tablet X closely with our very passionate community of users over the last six months to offer an unrivalled touchscreen typing experience. Finally, we’re excited to offer it to the market as a whole.”

SwiftKey X supports all Android 2.X smartphones and retails at $3.99 (£2.50). SwiftKey Tablet X supports all Android 2.X/3.X tablets and retails at $4.99. Both apps are available via the Android Market and Amazon Appstore.

To commemorate the first anniversary of SwiftKey’s beta launch, TouchType is offering a 48-hour promotion of SwiftKey X and SwiftKey Tablet X for $1.99 each, from 6am PDT today, 14 July, until 6am PDT on Saturday, 16 July.
