I’ve found half page turns to be a super useful thing when working with an iPad and digital sheet music. It helps allow you to do both pedal changes and bluetooth foot pedal page turns, as well as reading “across” the page when practicing.
I’m using the forScore app for iOS – I highly recommend it as a way to view and manage sheet music on an iPad. https://forscore.co/
I did a longer episode talking about my experience using an iPad in place of paper music: http://www.joshlayne.com/harptuesday/ep-113-sheet-music-on-tablets-forscoreipad/
