It is similar to the Blackberry SureType keyboard layout, 2 letters per key. But sadly it is nothing like the Suretype on Blackberry, nowhere near as smart in figuring out what you are trying to type. And some simple words like "for" fail miserably and end up being "doe" if you are not paying attention. Another downside to the "Better Keyboard" app is that in some apps when typing you could not see anything other than the current word being typed, as soon as you hit the space bar or moved onto the next word it will disappear from the text box. It was still there, just not visible, seems like quite the big flaw if you ask me.
