Swiftkey X is among our favorite Android keyboards because it learns from your emails and texts so it can predict what you'll type next, and the latest version gives you an idea of how sloppy you are with a heatmap of your typing accuracy. You also get a new stats panel you can share with your friends — that way you can do Swiftkey's marketing for them. In addition, you get improved prediction through blog and RSS learning and a long overdue feature for bilingual users: the ability to switch between keyboard layouts without digging into the settings. Unfortunately there's still no additional language support — Hebrew, Greek, and Arabic users have been waiting for a while now, as have speakers of Asian languages. Watch for the update to roll out in the next few days.
