SwiftKey is a popular keyboard for Android. The latest beta version is available to download and aims to improve your typing experience. It has great word prediction that learns how you type. You can speed up how quickly it learns by letting it see how you write in Gmail, Facebook, Twitter, or your blog. There are several themes to choose from and plenty of customization options.
The beta is not only a great way to get in on the latest features, but it is also free. SwiftKey Tablet X (version 188.8.131.52) is available in the Google Play store for $2.99. Newer features and free sounds like a good deal to me. You can download the keyboard from SwiftKey’s website.
