I use SongBook Pro by LinkeSoft. The details and some useful files can be found on my post here:
I use the Windows Tablet version of Songbook Pro on a PC and there is also an Android version which supports MIDI. Here:

And there are Mac Os and iOS versions which I know nothing about.
Good luck.
I am very happy with my setup. I select a song from my list and the right beat and tempo are pre loaded automatically so I can focus on the audience instead of on the gear.
