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.

ReceptionRating · Positive reviews · Number of ratings

iFretless Guitar holds the better App Store score, 4.2 against 3.0. That said, the two scores are not equally well evidenced: iFretless Guitar has 29 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 63% of Sing's written reviews are positive against 55% of iFretless Guitar's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Sing ships an update every 6 months, iFretless Guitar every 2 months. The most recent releases landed on October 8, 2026 and October 26, 2026 respectively.
