Actually I think the OP is referring to your reading speed and Kindle estimating time left I until end of chapter? I noticed the iPad app doesn't do this as my Nexus 7 version does. Maybe an update will address this feature in the future? Not sure why the Android app gets it while iOS does not. Yet iOS gets the page turn animation setting yet android does not. Who knows Amazons strategy for competing OSes. Maybe they gimp features in the hopes you buy a Kindle.
