I, and almost everyone I know and jam with who uses song sheets, use LinkeSOFT Songbook on Android, iOS or PC. It works with page-turner pedals, has the option to auto-zoom songs to one page, transposes keys on the fly, scrolls if required, displays chord diagrams for many instruments if required and loads more. Personally I find PDF's much less flexible and versatile.
