Used to be better, not it is slow and pages dont advance well.
I first started using this app on my lowly iPhone3G, and later on my ipad2. It was fast, responsive and worked well. Now on my shiny new iPad air (which is supposed to have a processor at least 4x faster) the app feels sluggish and unresponsive. Worse: the behavior of the page advance command (swipe left) is incorrect: it should advance a full page leaving full pages displayed, but instead it leaves 1/2 a page of the previous and 1/2 a page of the next page displayed. It is VERY HARD to swipe just enough to make a new whole page appear. Looking for a different app until this gets fixed.
