Classical Guitar Tools

Classical Guitar Tools is the complete toolkit for the serious guitarist: a precision chromatic tuner, a stage-ready metronome, acoustic string-health diagnostics, a sheet-music library, and an AI technique coach — all in one beautifully crafted app.

CHROMATIC TUNER
Fast, accurate tuning with tone alignment and one-tap reference tones from low E to high E. Play the reference tone from Control Center or ask Siri — perfect for ear training.

PRECISION METRONOME
Every time signature from 2/4 to 7/8, with crisp audio ticks or silent haptics you can feel. On Apple Watch, turn the Digital Crown to dial in the tempo without missing a beat.

ACOUSTIC STRING HEALTH
Pluck three times and see how each string measures against its own fresh-string baseline. Track sustain, early high-frequency response, and retention over time, so you know exactly when it is time to restring.

SHEET MUSIC
Import your scores as PDFs from Files or any app with the share sheet, and your library syncs to your private iCloud. Read in a dark, music-stand-friendly view, annotate directly on the page, and pick up right where you left off.

AI TECHNIQUE COACH
Snap a photo of your playing position and get severity-rated feedback on posture, wrists, and hands, with exercises you can try right away. The photo is erased immediately after analysis.

PRIVATE BY DESIGN
Tuner, metronome, and health measurements run entirely on your device. No audio is ever recorded or stored. Your sheet-music library lives in your private iCloud.

See it. Measure it. Master it.
