A free program for Android, by Yamaha Corporation.

This is a handy application for any guitar player, especially for those who are just starting out. It offers a basic and intuitive interface that lets you access the main functions with a simple tap of your finger.

The first thing you will notice about this app is that it is free. You will not need to pay a penny to use it, which is great because it does not require any personal information from you to work.

Another thing is that this app is very easy to use. All you need is a device that can connect to the internet and a camera to register your guitar.
