Download

GuitarTuner is located by default in the Applications Folder at the last position, so normally you have to scroll down.

The operation is quite easy and intuitive and well known from other instrument tuners. GuitarTuner is chromatic which means that not only the six guitar strings are detected but all other notes from the deepest bass up to the highest piano key.

(In addition also non musical tones can be analyzed for examples mechanical vibrations of engines)

The display depends on the orientation, which is detected automatically :

 


Like a standalone instrument tuner it is able to analyze a tone of a guitar (or nearly every other instrument) and show the note and the mistuning using a pointer and bar display. In addition (which not standard for other tuners) this software shows the input level.

<Up>/<Down> : Change tuning from 440 Hz (can also be used to calibrate)
 <Mode> : toggle between FFT-Mode (standard) and ACF-Mode (enhanced precision for bass strings)

How to connect an electric guitar

(First of all, you can tune your E-Guitar over the air – try it, often this works!)
The only thing you have to do is to manufacture a simple adapter cable from the 6.3 mm connector for the guitar to the connector equivalent to your headset (3.5 or 2.5 mm depending on model)

Buy the two plugs and a short two-wire-cable. Solder the connections shown in following figure:

 

When connecting to the phone, select “Headset” from the menu.
