Swift Key 3 also has some new features like Smart Space which fixes typos even if you miss spaces as you type. Two new themes are available to give you a bit of customization. The layout has been tweaked to make room for a larger space bar and a quick punctuation key among other improvements. Seven new languages are supported for international users following the update, and the word prediction engine now gives you the right word most of the time.
SwiftKey is available in the Google Play Store for $3.99 and requires you to be running Android 2.1 or higher, but then again, who isn't? There also is a free version for Android phones and both a free and paid version for Android tablets.
