A free app for Android, by NETIGEN Music Tuners.

This application has been designed to be the best tuner for violins. The idea is to make the process of tuning the violin as easy as possible.

The application has two modes:

Pitchfork mode – this is the most simple and quick method of tuning your violin. You just need to play the sound of each string a few times. The algorithm will recognize the sound and calculate the pitch.

Auto tuner mode – this is more precise and will tune your violin better. You just need to play the sound of each string and the application will recognize the sound and calculate the pitch.

In both modes, you can use the auto-tuner.
