Well....I was curious as I never heard if "Jellynote"

Here's some mixed reviews that I did read:
https://www.amazon.com/Jellynote-Tabs-Sheet-Music/product-reviews/B00TZT417U

From what I read I would pass it on by....pretty funky from my perspective.
It does not even come close to a BIAB "comparison".
If you want sheet music just go here: www.sheetmusicplus.com
I've bought several songs from them over the years and well worth the $3 buckaroos.

It may be OK for you depending on your current skill level.
Judgement call for you.

Probably doesn't help much but that my take and you got a bump.
Let us know if you do buy it so others can learn from your experience.

Carry on....
