PhonTuner voice and guitar tuner for Smartphones

PhonTuner screenshotAfter watching American Idol a few times we're pretty sure there's more than a few people out there who could use a little pitch improvement, so William Hung, this one's for you. If you've got a Smartphone, PhonTuner will help you perfectly tune your voice, guitar, violin, or piano over three octave ranges in realtime, and what's more, it's got fancy graphical interface. So why do we have a feeling that 50 Cent would totally segfault this app?
