Developer Description

High-performance guitar tuner app with high noise tolerance and accuracy

"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.

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

I've tried maybe 10 guitar tuner apps and this one is the best so far. better than da tuner, gstrings, fender.

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
