Good on iPad, needs help on iPhone – PragPub Magazine app Review
While useful on iPad, there's just too much zooming and panning on iPhone to be worth it. Even on 6 Plus. Though in land scape if it stuck to one page, instead of trying to show two, then one could scroll down the page and then swipe to the next. That would probably be usable on 6 Plus. Everything else is probably going to need dynamic formatting a la ePub.
