SwiftKey 4 is one of the best gesture keyboard apps ever. It is so good at predicting what you type, it borders on being creepy. I can rattle off e-mails, tweets and text messages to friends about sports, movies, tech, music — and based on what I’ve typed, SwiftKey occasionally finishes sentences word by word.
It does this by collecting data on what is typed as it’s typed. The data is collected anonymously, feeding the app’s learning algorithm to predict what you’ll type next, based on what you’ve typed in the past. It’s not perfect, but it always offers suggestions, right above its keyboard.
As you’re swiping across your phone’s display, SwiftKey guesses what you’re typing. Those guesses change as you type more letters; when you see the word you want, just lift your finger. Or, keep swiping the letters of that word and then swipe down to the spacebar for a space, then start a new word.
If you’re already using SwiftKey, the upgrade to the 4th generation of the app is free. Otherwise, SwiftKey 4 is a $3.99 download.
