User Theory: Custom Chords
v1.2.4: Custom Chords One challenge was making user-created chords behave exactly like built-in ones. That means anything the creates can be explored using the same visualisation engine, instead of being treated as a separate feature. It opens the door to a much more user-driven experience.

User Theory: Custom Scales
A few months ago SQNTIAL could only show the theory I shipped with the app. Today it crossed a milestone. You can now create your own scales, save them, and explore them directly on the fretboard. It might seem like a small feature, but architecturally it changes a lot. The app is no longer limited to a fixed theory library—it’s starting to become a workspace that musicians can extend themselves. This release includes: * Custom Scales * Local persistence * Automatic or manual interval labels * Direct integration with PLAY Next up is continuing to expand User Theory.

Hi! I’m Andrew, solo developer of SQNTIAL. It began as the learning tool I wanted for myself. Today I’m building it for musicians who want to understand, not just memorize, the fretboard.
