Tonarly: Vocal Pitch Monitor

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

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
• 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.
