Sing-inTuna!

Are you singing in tune?Learn to sing (or play an instrument) in tune with HotPaw Sing-inTunas color-coded pitch graph. Sing-inTuna uses the built-in microphone on your iPhone or iPad to analyze and help you visualize if you are singing, or playing a musical instrument (such as a violin), precisely on the right pitch. It only listens so that you can see your pitch note and how well your pitch matches that of a properly tuned equal-temperament instrument.
