My newest app is one that I think will become a favorite, but there's a bit more of a learning curve involved than with most apps. It's
Notion 5 by PreSonus and it's music notation software. It's $14.99 at the iTunes store and I've already bought the handwriting add-on for $7.99, and there are several instrument pack add-ons that can also be purchased from within the app (the ALL bundle is $29.99, but there are several cheaper bundles for $2.99 and individual instruments for 99¢). The good news is that several instruments are included in the original purchase, although to access them you have to register with a working email. In addition, if you have the $149 computer software installed on your pc or Mac (I don't), you can switch back and forth between platforms as you work, and in addition, on your computer you can compose to film.
I haven't yet reached a comfort level with this app yet as I just purchased it a few days ago, but I'll let you all know at a future date what I think of it and whether it was worth the (so far) $22.98 I've spent on this (not to mention the $22.00 I spent on
this stylus to make the notation more precise!).
BYW, the stylus rocks, but I'd like one that's fatter in my hand. This one's rather thin.
