SonaMetro recently released version 2.0 of Guitar Notebook, providing guitarists with a redesigned experience and new features. It's available as a free download for iPhone, iPad, and Mac:
Guitar Notebook features FlexFrets, an innovative notation method similar to chord diagrams that enables guitarists to tap in patterns that span any number of frets.
Version 2.0 includes the release of the Mac version of Guitar Notebook, so users can seamlessly move between iPhone, iPad, and Mac.
A redesigned experience is more intuitive and flows from Song to Page to Fretboard, as well as displaying fretboard thumbnails on iPhone, and new motion help screens.
Pro users can now add a Capo to their guitar on any fret.
A new Lifetime In-App Purchase option ($19.99) provides all current and future pro features for the life of the product.
