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:

  • SwiftKey Flow: World’s most accurate gesture input. Write by gliding your finger on the keyboard.
  • Multimodal - SwiftKey Flow can be mixed with tap input, with switching mid-word.
  • Mid-word completion: when you see the word you want just lift your finger off and the word will be inserted.
  • Flow Through Space: Gesture multiple words without lifting a finger, just by sliding your finger down to the space bar between words
  • Flow with next-word prediction: when you finish flowing a word, SwiftKey immediately shows you its best guesses for your next word
  • Three SwiftKey Flow candidates: tap backspace after completion of a flow to see three potential words
  • Easier corrections: Tap anywhere on any word to choose an alternative from SwiftKey’s three best guesses, based on the context and on your input
  • Better personalization: More thorough learning of your language and typing style - size of personal language profile increased in SwiftKey’s real-time prediction engine.
  • SwiftKey automatically detects writing style - SwiftKey predictions will tend towards completing your word or correcting your mistyping depending on your behavior - no need to select “rapid” or “precise” as in previous versions
  • Better predictions: Enhanced language engine, predictions in more text fields (as requested by our users)
  • 60 languages: Now including Albanian, Bosnian, Javanese, Sundanese, Thai, Vietnamese
  • Improved layouts for Russian and Korean.
  • Multi-colored ink: The on screen ‘ink’ that shows progress of a flow uses a multi-layered effect to show the beginning and end of a ‘flow’. Ink color complements the keyboard theme selected
  • Hold to delete: Long-press the delete key to remove the whole word. Deletion accelerates as you continue to hold. Slide to delete gesture can only be used when SwiftKey Flow is disabled.
  • Update by Artem: Something that wasn't mentioned in the changelog - I noticed v4 finally lets me write [email protected] correctly without spacing after the period. Hallelujah!

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.
