Fantastic tuner, tone generator a useful intonation tool.

I wish this tuner app had existed before I bought a couple other tuners for more money (namely iStroboSoft and PolyTune).

An easy to read implementation of several types of frequency visualizations.

The tone generator is a great one too, though I wish you could add a simultaneous second note, like a perfect fifth, above the generated tone, and also tune the tones manually.

Great job, I hope you make a ton of money.
