The idea was to create a simple yet beautiful (free) guitar tuner for iOS that works amazingly. As a guitar player, I am disappointed by the free guitar tuners on the App Store, so here is the proposed remedy.
Pure Guitar Tuner Google Group for interest.

Feel free to fork the repo and open a pull request. Using fairly normal convention, make changes in a separte branch then request to pull into master.
I lack the sound detection skills on iOS to get the frequency detection working well, but I'm sure we can make it work together.
