Harmonic Violin Tuner app for iPhone and iPad

You can tune your violin using the standard A440 tuning or classical Bach time tuning using the real violin sound. You can also tune your violin using a frequency from 428 hertz to 452 hertz as the A note.

With A440 and harmonic tuning, you can play the single pitches G, D, A and E with a real violin sound. From 428 hertz to 452 hertz tunings you can play the pitches G, D, A and E with a sine wave generator.

The program tells you quickly and precisely with the accuracy of a tenth-semitone step when the violin is in tune.

You can also use the program to tune other instruments such as guitar or ukulele.
