Its not a keyboard app its THE keyboard app ( atleast thats my opinion and as you know opinions vary) it basically allows you to "swype" ur finger across the keys of the keyboard and figures out what word you were trying to type , thereby saving you the hassel of poking at each key seperatly.
There are multiple cabs in the forum here check it out and see if u like it.
