Vocal Pitch Monitor: Tonarly

New in 2.0: a live vocal pitch monitor with a real-time pitch trace, faster note detection, and Pro chord ID — fully redesigned. Free to try, all on-device.

Instantly see the exact note you're singing or playing — in real time, right on your iPhone.

Tonarly turns your microphone into a live vocal pitch monitor and music note identifier. Sing, hum, strum, or play any instrument and watch the note, octave, and cents meter update the moment you make a sound.

WHY TONARLY • Live pitch monitor — a precision cents needle follows your voice so you can see exactly how sharp or flat you are, note by note • Music note identifier — get the exact note and octave from any sound: voice, piano, guitar, violin, ukulele, and more • Real-time pitch trace — watch your pitch move over time and hold notes rock-steady • Chord detection (Pro) — strum once and get the chord name, the notes inside it, and a fretboard voicing • Your notation — letters (A B C), solfège (Do Re Mi), or ドレミ • Tunable reference — calibrate A4 anywhere from 435–445 Hz • Any instrument, any voice — a C is a C, whatever makes the sound

PERFECT FOR

• Singers warming up and checking pitch accuracy • Guitarists figuring out chords by ear • Pianists checking tuning or transcribing • Music students learning notes, intervals, and solfège • Songwriters finding the key of a melody in their head • Producers identifying samples and reference tracks • Anyone curious about the music around them

HOW IT WORKS

Open the app, tap the mic, and play. Tonarly captures a short audio window and analyzes the pitch using studio-grade DSP — the same class of audio engine used in professional tuners. The result appears in under a second.

Switch to the Monitor tab for a continuous live readout that updates as you sing, hum, or play. Use the cents meter to fine-tune your pitch with precision.

Switch to Chord mode to identify entire chords at once — major, minor, 7th, sus, and diminished — in real time, on any instrument.
