Can you sing in tune? Learn to sing (or play an instrument) accurately in tune with HotPaw Sing-inTuna's 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 graphs pitch on a scrolling graph resembling a musical Grand Staff. Tones that are on-pitch (+-20 cents) are colored green; notes slightly sharp: red; notes a pinch flat: blue.

You can also display an optional pitch frequency spectrum of your voice to see your timbre.

Sing-inTuna requires a quiet environment with no accompaniment or harmony, and monophonic pitches that are at least a quarter second long. The pitch range using the built-in mic is about +-2 octaves from middle-C, depending on microphone use, loudness, and timbre.

Note: This app produces no sounds and shows no sheet music. It only listens so that you can see your pitch, and how well your pitch matches that of a well tuned equal-temperament instrument.

Great for excercising your voice and pitch. I would give it 5 stars if I could set the notation relative to my voice when I sing bagpipe tunes which are on the treble clef. Only problem is I have a low voice.

Overall, a wonderful app to build your confidence in sounding notes especially for real singers. I'm a novist but this is really fun!

Doesn’t work for men.

Does not detect any pitch at all for male voices. It can only detect notes at the very top of my range.

A dream made real!

This is THE REASON a musician needs an iPhone. What a dream come true this has been! I don’t even know where the old guitar tuner went because I alway tune with this app and even practice with my cello and use it to help my intonation. Again this is a dream come true. Get it. Thank you to the dev team. I couldn’t be happier!
