Furio Guitar

You either practise or you don't. There is no demo mode.

Furio Guitar is a chord and scale library for the instrument you already own. Choose a key, choose a scale, and the neck fills in — not a photograph of a fretboard, the actual positions, laid out along the neck the way every chart you've ever read lays them out.

The fretboard. Scales, chords, triads, or a free board you fill in yourself. Degrees or note names. CAGED boxes when you want the window fixed, free position when you want to move it. Guitar and bass, standard tuning or your own.

Triads. Pick a quality, a string group and an inversion, then walk the shape up the neck and watch it change under your hand. This is the part most apps skip.

The tuner. Pitch in cents, not a green light. Standard, Drop D, half step down, and bass tunings.

The metronome. It keeps time wherever you are in the app. Stopped, it folds into the tab bar and costs you nothing. Running, it takes one shelf and hands the rest of the screen back.

Today. Yesterday's work comes back as today's first drill. Thirteen minutes counts.

What it doesn't do. No account. No ads. No subscription. No analytics. The app never sends anything anywhere, because there is nothing to send — everything runs on your phone, including the tuner's listening.

Available in English and Spanish.
