I understand how Jack can say that.... I did a quick Google search and found this example:
http://thenextweb.com/apps/2015/05/2...book/bookerly/
I then copied the two images and pasted them into layers, forcing the hue/saturation of the Bookerly layer such that it looked red and then moved each word so that the words lined up (making no effort to affect spacing of the letters)... they sure look close to me.
(looks like I lost the word Those, but it's only a few pixels different as well)
