Chromatic Tuner: Guitar & Mic

About

Play a note and know instantly whether you are sharp, flat, or dead-on. Chromatic Tuner listens through your iPhone microphone and shows the note name, the octave, the exact frequency in Hz, and how many cents you still have to move. Most tuners give you a needle and nothing else. This one gives you the number too: a rotary dial that sweeps 50 cents each way, a green lock zone the moment you are inside 4 cents, a live input-level meter so you know the mic is actually hearing you, and a history tab that quietly records every note you lock in — so you can see whether your intonation is really improving or just feels like it. WHAT YOU GET - See the note, octave, Hz and cents offset the instant you play a string - Know which way to turn the peg — the needle and its color tell you sharp or flat at a glance - Tune guitar, violin, ukulele, cello, trumpet or piano from six built-in standard tunings - Hear a clean reference pitch on demand with the built-in tone generator: sine, triangle or square, octaves 2 to 6 - Tap any string in a preset to hear its exact pitch and tune by ear when the room is too loud for the mic - Watch your accuracy improve with an average cents offset, a locked-in count, and a chart of your last 20 tunings PERFECT FOR - Guitar and bass players who retune before every session and every take - Violin and cello students grinding on intonation - Ukulele, trumpet and piano players who just need one clean reference note - Singers who want to find a pitch and hold it WHY NOT JUST USE A CLIP-ON TUNER Because the clip-on is in the case you left at home, running on a battery you forgot to replace. This one is already in your pocket, it reads to the cent instead of guessing with three LEDs, it plays reference tones a clip-on never could, and it remembers how close you actually got last time. PRIVACY Audio is analyzed on your device and is never recorded, uploaded, or shared. No account, no sign-up, no ads, no tracking. Everything works fully offline, including in a rehearsal room with zero signal. FULL ACCESS Premium unlocks the whole app: chromatic microphone tuning with the live needle and input-level meter, all six instrument presets with tap-to-hear strings, the tone generator, and tuning history with accuracy charts. Choose a weekly plan, a yearly plan, or a one-time lifetime purchase if you would rather pay once and never think about it again. Open the app, play your low E, and watch the needle lock.
