From the first pluck to the final page, GuitarTools covers the fundamentals — and the fine details.
Fast, accurate tuning with tone alignment and one-tap reference tones from low E to high E. Play the E-string tone straight from Control Center or with Siri.
A metronome that feels like an instrument: audio and haptic ticks, every time signature from 2/4 to 7/8, and crown-controlled tempo on your wrist.
Pluck three times and see how each string measures against its own fresh-string baseline — sustain, early high-frequency response, and retention, with trends over time.
Snap a photo of your playing position and get severity-rated feedback on posture, wrists, and hands — with exercises you can try on the spot.
Import your scores as PDFs from Files or any app with the share sheet, and they sync 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.
Clean, glanceable screens built for music stands, dim stages, and busy hands.
