What is a chromatic tuner?
A chromatic tuner listens to pitch across all twelve notes in an octave — not only open strings. That makes it useful for guitar, band, orchestra, and voice: play any note, see how far you are from in-tune in cents (1/100 of a semitone).
Browser tuners use your device microphone and Web Audio. On iPhone, use Safari and allow mic access; Add to Home Screen keeps the app fullscreen for rehearsal.
How to use an online tuner well
Quiet the room, hold the phone near the instrument, and play a steady tone. Watch the needle or cents readout settle — don’t chase every flicker. For winds and strings, tune at performance volume when you can; soft pitches can read flat on cheap mics.
- Allow microphone permission when prompted
- Aim for near 0¢ on the target note
- Use transposition if you play Bb, Eb, or F instruments
- Cross-check with a drone or piano when learning intonation
Free online vs download apps
Some practice apps put tuner, metronome, and recorder behind a download (and sometimes a purchase). That works well if you live in one app every day — but students who only need to tune for five minutes may not want that step first.
A free online chromatic tuner in the browser is simpler for a quick check: open a link, allow the mic, and tune. When you want the full loop (record, journal, theory paths, advanced tools), the freemium iPhone app is ready — without charging before you hear pitch.
