About this app

Free. Professional guitar tuner with high precision. Complete chord library with thousands of guitar chords. Metronome with perfect timing.

Guitar Toolbox is a collection of the three essential tools you need to learn guitar: a metronome, a guitar tuner and a chord library. Everything in the app is 100% free and of professional quality.

Professional guitar tuner
Whether you use an acoustic guitar or an electric guitar, you need a guitar tuner to be perfectly in tune. Easy to use for beginners, our tuner will allow you to be perfectly in tune so you can play guitar like a pro. Our algorithm was specifically tailored for guitar tuning, so you can be sure to get highly professional precision.
You can use our guitar tuner in automatic mode, where the tuner will automatically detect which note you're playing. You can also get real sounds to tune your guitar by ear. And there's a chromatic mode included if you cannot find the guitar tunings you want to use.

Chord library
The chord library contains chord charts for every chord and position you might need. From beginner open chords and power chords to barre and more complex jazz chords, they're all here for every key possible. The charts will also show you the precise fingering to use for each chord position, as well as music theory information with name of notes and intervals.

Metronome
Practicing with a metronome is a must for every professional guitarist out there. With our metronome you can be sure that it will always be on time and allow you to practice any meter and tempo you want, even if you want to play polyrhythms.
There is also a speed training module to help you get faster and more precise technique on guitar, so use it to unlock your inner shredder.
