The day is finally here, SwiftKey users – the all new SK 4 is live in the Play Store! No longer a beta, this version includes SwiftKey's take on gesture typing, Flow. Flow is unique in that, unlike other gesture-based keyboards, it allows you to continuously swipe through entire sentences without ever lifting your finger - the company calls it Flow Through Space. If you've been using any of the beta versions, then you already know what a fantastic feature it is, and now it's finally mature. Not only that, but Flow is part of SwiftKey 4, which is a free upgrade to existing SwiftKey users.

That's not the only feature v4 brings, though – there's a veritable ton of new things in this build. Take a look:

It's worth noting that v4 will inherit your dictionary and some other settings from SwiftKey 3 by default. If you have the Flow beta installed and would like for SK4 to pull its info from that instead, simply uninstall SK3. Likewise, if you'd rather it pull from v3, go ahead and uninstall the Flow beta just to be safe.

While SwiftKey 4 may be a free upgrade for existing users, newcomers to the keyboard can get it for a promo price of just $2 (normally $5) for either smartphones or tablets. You'll find widgets for both versions – as well as their trial-based counterparts – below. Happy Flowing!

Update: Note that it may take a bit for everything, including the sale, to propagate. Please be patient if you're not seeing v4 just yet - it's definitely getting there:

Update #2: SwiftKey just put up a blog post welcoming everyone to v4 as well.
