Features & Capabilities

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.

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

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!

Not much you can use this for. But it's ok if you just want to maybe check pitch a little... Doesn't put much on the screen. Doesn't have sound, Definitely not worth ten bucks.... May be 1.99 the most.
