About this app

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

In many tuner applications so far, the indication tends to be unstable due to noise, which prevents the smooth tuning.
G-Tuner greatly reduces the influence of noise by our pitch detection technology specialized for the microphone input, and it makes players free from the frustration.
And also about basic performances such as accuracy and responsiveness of indication, we have achieved a high level that can be used in professional applications.
While the interface is simple enough even for beginners, it also offers some practical options to meet advanced requirements.

Ratings and reviews

I updated this app but the new version is unstable and does not respond correctly to the sound of the strings. When I tried to tune a string, the indicator kept going flat and sharp. I have reverted back to the older version 1.1.1

This is the best tuner app, Period. just get the pro version for the awesome experience.

Awesome simple to use tuner! I have several on my phone and I have numerous actual clip on tuners and this one is easy to see (I've only got use of one eye). My dad even said it's one of the best tuners he's used as well and he's in his early 60s!
