Well, Mobile Sheets is actually quite good at transposing chords, if you create a file in chordpro format, instead of pdf. Adding extra notes, either typed in or handwritten, is also very easy and works well.
Transposing tablature like you have in the example you linked to, I don’t think would work at all.
Mobile Sheets is very affordable, and if you just use it to load scans of your handwritten song charts so that page turning and page scrolling, and building set lists, and sharing song charts with other musicians, then MobileSheets can be worthwhile.
If you already have MobileSheets, even just the trial version on Windows or Android, I’d be happy to send you a song chart file that is in chordpro format that you could import and see how transposing works.
