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. Developed by D'Addario & Company, Inc., the world's largest designer, manufacturer, and distributor of musical instrument accessories, D'Tools offers a wealth of easy-to-use, professional-grade guitar utilities in one elegant application for your iPhone or iPod touch.

With D'Tools, guitar players can explore a library of over 7,000 guitar chords by simply tapping and strumming the touch screen. The app allows users to view chords in every position up and down the guitar neck and hear each one played back in pristine audio. It even includes a "lefty" mode for left-handed guitarists.

In addition to chords, D'Tools also offers a chord finder feature, which helps users discover the proper name for a chord by selecting frets and finger positions. The app also provides thousands of scales, modes, and arpeggios to practice, allowing users to improve their technique and boost their versatility. Unique and challenging fingerings, such as "big stretches," are also available.

D'Tools includes a professional-grade digital tuner powered by Audiofile Engineering's precise AETune pitch detection technology. Users can choose between a strobe or needle interface and access dozens of presets to keep their instrument in tune. The app also features a hyper-accurate and visually stunning digital metronome to help users keep time. Tempos can be set numerically or by tapping the touch screen, and users can choose from multiple sounds and time signatures.

D'Tools, developed by Audiofile Engineering, is a must-have for guitar players looking for a comprehensive utility kit. Whether you're a beginner or an advanced player, this app provides all the tools you need to enhance your guitar playing experience.
