Chord Graph is a native app for Mac, iPad, and iPhone—same theory engine, layouts tuned for how you actually use each device.
A spacious three-column layout: sidebar controls for key, mode, and chord quality; the harmony graph in the center; and an inspector for explanations and progression tools. Ideal for writing sessions at your desk or on an iPad with keyboard.
A tabbed layout optimized for portrait—Key, Graph, and Inspector—so you can explore harmony on the go without cramming three panes onto a small screen.
Chord Graph is available on the App Store for macOS, iPadOS, and iOS. Replace the link below with your live App Store URL when you publish.
Start from any chord. Follow the graph. Hear the path. Understand the why.
