For Funiculus to be the best, most versatile microphone-based guitar tuner in the world...hardware or software.
And not-so-incidentally, one of the least expensive, with a price tag anywhere in the range of FREE to $2.
Obviously, it's not there yet. The graphics will be refashioned, and the algorithm will be enhanced even more. Please leave comments on what else Funiculus needs to do better in order to be better than your current tuner. Notice I say "microphone based" because the iPhone obviously doesn't have quarter-inch inputs to plug an electric into. (If someone wants to develop a device that would interface the iPhone with an electric guitar, then I could modify the software to accommodate this, but I don't see this happening.)
In the meantime, jailbroken iPhone users can expect more updates (free of course). For the next version, based in part on suggestions, I will include pitch transposition stuff, more stringed instrument tunings, and new "faces"...a tuning fork module as well as a tap-it-out rhythm module. (For an example of this, you can check out a novelty app I did: "Cowbell", available on Installer.)
