I started with unRealBook, my one complaint is that it is a photo and nothing can be added unless you scan it again. I want the option to add to and change the song. And there are times when I add a complete second song on the same page with Copy and Paste.

My PDF reader can send a song to OnSong – no pasting

Make a set and then you can always change their order by edit and sliding the song where you want it.

1-Change the size of the lyric font, the spacing of lines, the tittle font, the chord font, and transpose all on the same edit page.

2-Highlight the chords with color.
You can make all these changes with the lyrics and chords. If you use staff and notes OnSong cannot add or change anything.

If I turn the IPad from vertical to horizontal the lyrics become larger; far more than I need to reed.
The person who created this App is a thinker. One slide on the IPad and one push on the keyboard and I am ready to do the next song.
