Tuner: Guitar, Ukulele & Bass
Chromatic Tuning & Metronome
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Tuner is a guitar tuner that listens through your microphone and shows you, string by string, whether to tighten or loosen. It also tunes bass, ukulele, violin, cello, banjo and mandolin, and has a metronome built in.
TUNE BY NEEDLE
• Auto mode finds the string you play and points the needle at it.
• Manual mode locks onto the string you choose.
• Chromatic mode shows any note, for any instrument.
• The needle turns green when you are within 5 cents.
WARNS BEFORE A STRING GETS TOO TIGHT
If a string is pulled well above its target, or a whole octave too high, Tuner tells you to loosen it before it snaps.
19 TUNINGS FOR 7 INSTRUMENTS
• Guitar: Standard, Drop D, Half Step Down, Full Step Down, DADGAD, Open G, Open D, Open E, Drop C
• Bass: Standard, Drop D, 5-String
• Ukulele: Standard (High G), Low G, Baritone
• Violin, Cello, Mandolin: Standard
• Banjo: Open G (5-String)
Every tuning is included.
TUNE BY EAR
Tap a string to hear its reference note, played as a plucked string or a pure tone. Piano and organ sounds come with Pro, or open until you close the app when you watch a short ad.
METRONOME
• 30 to 250 BPM with a slider, +/– buttons or tap tempo
• 1 to 12 beats per bar, with an accent on the first beat
• Quarter notes, eighth notes, triplets or sixteenth notes
• Click, woodblock or beep sounds
The beat is played from a prepared audio loop, so it stays steady.
MORE
• Reference pitch from A4 = 430 to 450 Hz
• Note names as C D E or Do Re Mi
• A light vibration when a string is in tune
• Two extra color themes, with Pro or a short ad
• Your microphone sound is analyzed on your phone and never recorded or sent anywhere.
FREE WITH ADS, OR PRO
Tuner is free with ads. Tuner Pro removes all ads and unlocks every sound and theme. Choose a monthly subscription or a one-time lifetime purchase.
