A musical instrument tuner. It's accurate, easy to use, and highly configurable. Originally conceived to tune electric guitars, it can now be used to tune other instruments.

It looks like an analogue tuner, with a gauge indicating the relative shift to a certain note, found automatically as the closest note to the estimated frequency.
