This app used to work quite well, but now the controls for it are kind of garbage. Changing pages is super clunky- swiping works less than half the time, and trying to tap frequently registers as a center tap, pulling up menus or highlighting words, and then getting rid of the highlight is a pain in the butt! I can't figure out how that's supposed to happen- tapping on it doesn't work, the back button on my phone doesn't work, managing to turn the page doesn't work- it's dumb luck to resolve!
