Nice!

We’re you inspired by the GuitarTuna iPhone app?

This looks _very_ GuitarTuna. I've not come across another app which uses the (IMHO very effective) vertical scrolling pitch visualisation.

This is great though OP. It's the best browser-based tuner I've ever used. I really hope you don't get sued.

Yes, I did the app mostly for myself as I was getting disappointed with them adding too many unnecessary (IMO) features to it.
