Both SwiftKey X and Thumb Keyboard are sold through the Android Market, and at first glance their pricing seems comparable. After close examination, however, it’s clear that the capabilities offered by each app differ substantially. At $3.88, SwiftKey X costs about $1 more than Thumb Keyboard ($2.46). That said, Thumbs comes with a huge selection of keyboard layouts that support multiple devices ranging from phones to a plethora of tablets of various screen sizes. By contrast, SwiftKey X only comes in two versions, phone and tablet, with the later costing $4.99.
Winner: Thumb Keyboard.
In addition to boasting a lower price, Thumb Keyboard covers many more devices and offers much greater customization options.
