FretBuilder (iOS)

FretBuilder helps guitarists and other fretted-instrument players experiment with tunings, practice patterns, and visual references. The app keeps a library of the shapes you rely on most so you can revisit a voicing or exercise whenever inspiration strikes.

• Capture alternate tunings and instantly see how familiar intervals shift across the fretboard.
• Highlight notes, degrees, or scale shapes to plan exercises that match your current practice goals.
• Store multiple instruments in one place—perfect for switching between standard six-string, baritone, or extended setups.

• Songwriters: Collect new chord shapes that sit well in alternate tunings without keeping a separate notebook.
• Improvisers: Visualize intervals before you plug in, so time with the instrument stays focused on sound and feel.
• Teachers: Share annotated diagrams with students to guide weekly practice assignments.
