FretViz

Key Features Visualize Notes, Chords & Scales Instantly map out any scale or chord in any key across the entire fretboard. Learn to recognize shapes, patterns, and relationships between notes and intervals. Scale & Mode Selector From major and minor to exotic modes and scales, easily switch between them to expand your musical vocabulary and creativity. Customizable Color Schemes Enhance your memorization process with vivid, color-coded notes and intervals. Choose from preset themes or create your own color combination. Flexible Note Display Options Toggle between showing note names, scale intervals, or both — perfect for learning theory, memorizing fretboard positions, or improving improvisation.

Right- & Left-Handed Views Tailor the interface to your playing style with full support for both right-handed and left-handed guitarists. Persistent Settings Your preferences matter. FretViz automatically saves your settings — scale, tuning, display mode, orientation, and color scheme — so every time you open the app, you're right where you left off. No need to reconfigure each session. Whether you're visualizing arpeggios, jamming in Dorian, or mastering fretboard positions in alternate tunings, FretViz is your go-to guitar learning companion.
