A guitarist's practice toolkit, named for the musician's term for focused solitary practice. Tuner, comprehensive chord and scale libraries with formulas, chord progressions, classic practice exercises, a metronome extensible into a simple drum machine, and a Practice Mode that walks you through rotations of material at tempo so the app drives you rather than the other way around. The theory model generalizes to other stringed instruments (bass, ukulele, banjo).

Built in Rust with Xilem + Masonry for the UI (migrated from Iced 2026-05-18). Targets desktop first (Windows, macOS, Linux) with a planned path to mobile and web.

Pre-alpha. See design_docs/ for the product description, doc policy, and the active plan.
