Gibson on Wednesday launched its own iPhone app, giving users several unique features. The “Gibson Learn & Master Guitar Application” features a chromatic tuner, complete with alternate tunings allowing users to tune in Open G, Low C, Drop D and Eb, among others. The app also has a Standard Mode Tuner that allows you to tune each string to a sample tone, according to Gibson.

The built-in Metronome has multiple time signatures, visual and audio options, and a set-your-own tempo tap pad. It also comes with a chord library that is good for both beginners and advanced.

What makes this app unique is the addition of free video lessons in the app. Users can access full lessons from the Learn & Master Guitar course from within the app.

The app is free from the App Store.
