Newly updated to support the latest iPhones and iOS 12, D'Tools (formerly Guitar Tools) is the ultimate hand-held utility kit for guitar players of any style or skill level, brought to you by D'Addario & Company, Inc., the world's largest designer, manufacturer and distributor of musical instrument accessories. Enjoy the full functionality of the Chordmaster and Scale Wizard apps, the core features of ProTune and ProTempo. Developed exclusively for iOS by the minds at Audiofile Engineering, D'Tools packs a wealth of easy-to-use, professional-grade guitar utilities into one elegant application for your iPhone or iPod touch.


Explore a library of more than 7,000 guitar chords by simply tapping and strumming the touch screen. View chords in every position up and down the guitar neck and hear each one played back in pristine audio. There's even a "lefty" mode for the oft-neglected southpaw.

You know how to play it, but what do you call it? Select frets and finger positions to discover the proper name for your chord.

Improve your technique by choosing from thousands of scales, modes and arpeggios to practice. Try multiple positions and alternate tunings to boost your versatility. Use "big stretches" for unique, challenging fingerings.

Keep your instrument in tune with a professional-grade digital tuner, powered by Audiofile Engineering's precise AETuneā„¢ pitch detection technology. Choose between strobe or needle interface and access dozens of presets.

Keep in time with a hyper-accurate and visually stunning digital metronome. Set tempos numerically or by tapping the touch screen. Choose from multiple sounds and time signatures.


D'Tools was developed by Audiofile Engineering, a leading developer of audio software for OS X and iOS.
