The software and language engineers at Swiftkey have been toiling on this app for the past two years, and at long last, it's being made available for precisely nothing to anxious Android users. Hot on the heels of Swype's own beta, the Swiftkey beta is now available to download directly from the App Market, and once installed (along with language packs of your choice), it can be used in place of your stock Android soft keyboard. We've never been the biggest fan of Google's factory keys, and while we still feel that Swiftkey's letters are a tad on the skinny side, it's definitely an improvement. But that's not where the magic's at -- this software has an uncanny ability to guess what your next word will be, and it actually looks at your prior SMS list (if allowed) in order to "learn" how you converse. In our early tests, we're pretty darn impressed, and yes, it's definitely worth the $0.00 price tag. Get your download on right now, or hop past the break for a video demonstration if you still need convincing.
