I've used an AP called 'onsong' for lyrics and chords. You can search the Internet right from the Ap. you can also edit if you don't care for all the chords or lyrics.
I'll have to check out the apps above.
Currently I write all my docs in Page and save as both Page and PDF on my Mac. Then I transfer the tunes (lyrics n chords) to my iPad and store them in iBooks. I guess it's not the best but it works. It would work a LOT better if I knew how to create folders within iBooks so I can sort the music into genre rather than searching one huge long list.
To create folders in iBooks go to Collections and touch New. You can create as many folders as you require.
Thanks KevinJS... OK.. sorry, I'm an old coot w/o much tech ability.. Once the folders are created.. how do I get existing tunes that are in iBooks into those folders. Doubt there is a drag for this.. but.. ???
