Best text editor for IOS

[dcraftfrombr]

I have always used GuitarTapp to find my chord charts and then I would email the file to myself, open my email and open the txt file with Arrow Note, a free text editor. I could easily edit the file and then copy and paste into Set List Maker into the Lyrics window.
My problem is that apparently the author of Arrow Note needs to update his app to work with the latest IOS.
So my question is what is everyone else using? I tried a few others, but most of them when pasting into SLM, everything is double spaced.
Any ideas?
