Noteshelf, my favorite iPad writing app (yes, it has sheet music templates) is on sale for 80% off as part of a back to school sale. That makes the app $0.99.
If you are interested in good writing/notebook apps, you can’t go wrong. The app has all the features of penultimate, and a very equivalent writing experience–plus additional features.
Pair it with an Adonit Jot…and it’s a match made in iPad heaven.
