The Royal Conservatory has a series of theory apps available on iOS that correlate to their Celebrate Theory books. There are five apps: Levels Prep, 1, 2, 3, and 4.
While these apps correlate to the RCM program, you do not necessarily have to use the theory books to use the apps.
Like many apps out there, students cannot sign in to track their progress, so progress is tracked by filling out their music lab sheet.
