First off, if you need a music-notation app for your iPad, get this one.
Once you get used to the workflow, its pretty handy. Do beware, that as of now, the option to use the Apple Pencil for handwritten notation that gets translated into digital is an $8 in-app purchase.
Still though, this app is definitely worth the money. Needs a few more features like folder-organization for scores, but overall, its hard to complain.
