A.I.type Keyboard does a lot of stuff, but its most eye-catching feature is its "Float-N-Split" mode: On large-screened devices, the keyboard can be split into two separate halves, each of which can be resized and moved around independently.
A.I.type also includes some useful secondary key functions (activated by a long press) like copy/paste and undo. And it boasts an impressive array of visual options, including themes, custom background images, and custom key selection.
The full versions of the smartphone and tablet apps cost $3.99 each. Free versions are available; after 14 days, they lose basic text prediction and word correction features.
