Most fretboard tools let you look up one chord or one scale at a time. fretengine lets you stack multiple concepts at once: layer a chord and a scale on the same fretboard, view CAGED zones, draw highlights, and more. Pair that with 7,500+ chord voicings and scale patterns, integrated practice tools, and an intelligent guide with Navigator.
We happen to believe it’s better than any chord dictionary out there.
No. Every chord and scale comes with interval breakdowns and written explanations. Navigator meets you where you are and provides detailed music theory guidance based on your level.
No, Navigator works from the same voicing and pattern library that powers the app. You can trust that every chord voicing and scale pattern is vetted and playable.
No. We believe that making music is fundamentally human. Our focus is to help you become a better musician. Navigator can guide you to better music theory understanding and fretboard fluency, but the guitar playing is on you.
