I was curious as to if hookpad is included in the hook theory app
Currently the app is only available on our website. The hooktheory app is a book (there are 2 apps, one is our intro book, the other is a more advanced sequel that goes into secondary dominants, modes, etc.)
The standard version of Hookpad can be accessed at www.hooktheory.com/hookpad/app
it is free. The subscription premium version, Hookpad Plus, is not included with either of the books.
