Description
Music Theory Companion focuses on a clear use case: music theory, scales, chords, ear training & songwriting tool for all musicians. Instead of treating every listed option as equally important, this review looks at how the core tools work together and what a user should examine before relying on the app.
This app helps you develop your aural skills and relative pitch. It can help with improvisation, composition, arrangement, and interpretation. ✅ Scales & Chords lets users explore 86 unique heptatonic scales/modes and their diatonic triads/seventh-chord formations. The app has a wide list of scales for guitar, piano and vocal. These functions form the practical center of Music Theory Companion, allowing the main task to be handled from the phone without requiring a separate desktop process. Individual options may still vary by version, device, region or account type.
Music Theory Companion is likely to suit users who already understand the problem they want to solve and prefer a dedicated app over a collection of general-purpose tools. Occasional users may value quick access, while frequent users should pay closer attention to export options, notifications, battery use and account portability. ✅ Matching Chords lets users discover alternative chords for any note in any scale. ✅ Matching Scales lets users find alternative scales that can be played with any given scale. ✅ Circle of Fifths lets users visualize the circle of fifths for all 86 scales, with options for triads and seventh chords.
The source record reports an update date of 06 May 2026, but availability and requirements may have changed since that snapshot. Feature access can vary by version, region, device or account type, so the current in-app interface is the most reliable reference. Permissions should correspond to functions the user actually intends to use; location, contacts, camera, microphone, accessibility, storage and notification access deserve particular scrutiny when present. The developer’s current privacy disclosure, data-safety information and account-deletion process should be reviewed before sensitive or irreplaceable information is stored.
