The tuner is fantastic! If you purchase the All In One pack as I did on another device, you unlock all kinds of amazing tuners to use. There is a chord finder setting that listens and translates chords in real time, accurately! There is a sound graph setting that works like a seismograph, detecting every note being played and draws lines on a real time graph on the corresponding notes. It even shows curved lines representing crescendo and decrescendos, slides, hammer-ons and pull-offs and is 100% accurate. It also has a tone generator, can tune instruments other than guitar, i.e. piano, banjo, mandolin, lute, and many, many more. I recommend this to any musician, amature or elite.
