As its name suggests, Clarity Keyboard Beta is still a work in progress. It's the first product of a new initiative SwiftKey is calling Greenhouse, which should see a lot more experimental apps come from the company. We gave it a quick test and weren't particularly wowed by its corrections, although that's perhaps to be expected given the time it takes to learn your writing style.Despite SwiftKey launching on iOS last year, this beta is Android only for now. There are already some reported problems, such as compatibility issues with certain Samsung and LG devices, but SwiftKey is looking for feedback on the work in progress. It's available as a free download from Google Play, so you haven't got much to lose by giving it a spin.
