SwiftKey X 2.1 for Android tablets and smartphones just became available today, and brings a bunch of new features and bug fixes to your favorite touchscreen device. Since our hands-on with v2.0, TouchType has updated its on-screen keyboard using the feedback it gathered from its 25,000+ VIP members. The new version of SwiftKey X adds blog personalization, insights about your typing (shareable with friends), heat-map visualization (see screenshot above), localization / language enhancements, and an auto caps toggle. We've been using the final build of SwiftKey X 2.1 on our Nexus S for the past couple of days and noticed some improvements in terms of typing speed and accuracy. Pricing remains $4.99 for SwiftKey Tablet X and $3.99 for SwiftKey X. Full PR after the break.
