Gelato Tuner

Free, with no ads, no account and no tracking. Gelato Tuner puts a chromatic tuner, a metronome and a tone generator in one simple app.

Tuner • Hears any note from A0 to C8 and shows the note, how many cents sharp or flat it is, and its frequency. • A clear dial shows which way to tune, and a soft haptic confirms when a note is in tune. • Set the reference pitch A4 from 430 to 450 Hz, and show notes as sharps or flats. • The microphone is used only while the tuner is on screen. Audio is analyzed on your iPhone and is never recorded or sent anywhere.

Metronome • 20 to 300 BPM. Set the tempo with the dial, the plus and minus buttons, tap tempo, or a marking such as Andante or Allegro. • Time signatures from 1/4 to 7/4 and 3/8 to 12/8. Make any beat accented, normal or silent. • Eighth-note, triplet and sixteenth-note subdivisions, and six click sounds. • 16 drum grooves, including Rock, Funk, Hip-Hop, Reggae, Shuffle, Swing, Bossa Nova, Samba and Jazz Waltz. • Timed by the audio clock, so the beat stays steady and the display matches what you hear. • Keeps playing with the screen locked or while you use another app.

Tone • Plays a steady reference note from C0 to B5, in Pure, Warm or Bright. • Sub-bass notes down to 16 Hz for checking a subwoofer or a sound system. • Follows the tuner's reference pitch, so A4 plays at 440 Hz or wherever you set it. • Keeps playing while you tune by ear, switch tabs or lock the screen.

Gelato Tuner collects no data. There are no accounts, ads, analytics or in-app purchases, and it works without an internet connection.
