Description
"Playing the guitar is fun, but tuning it is a pain ..." G-Tuner will surely be the best tuner for players who think so.

While the interface is simple enough even for beginners, it also offers some practical options to meet advanced requirements.

Tried several tuners, and they all do a good job of tuning, but I really like the clear display layout of this one best.
