New: real-time chord detection + a precision vocal pitch monitor. Identify any note, chord, or melody from your voice or instrument!
Instantly identify any musical note or chord with your iPhone — just tap and play.
Tonarly turns your phone into a real-time music note identifier. Sing into the mic, strum a chord, hit a piano key, or hum a melody — Tonarly listens and tells you exactly what you're hearing in milliseconds.
Whether you're learning an instrument, transcribing a song, checking your pitch, or finding the key of a track, Tonarly gives you the answer instantly.
KEY FEATURES
• Real-time note detection — tap the mic, play any note, and see the letter, octave, solfège, and frequency in Hz with a confidence score
• Vocal pitch monitor — a live readout of your singing voice with a precision cents meter, perfect for warm-ups and pitch practice
• Chord identification (Pro) — detects major, minor, 7th, sus2, sus4, and diminished chords across any instrument
• Works with anything that makes sound — piano, guitar, ukulele, violin, bass, voice, whistle, hum
• On-device processing — your audio never leaves your phone, never gets uploaded, and is never recorded
• Solfège names — see Do, Re, Mi alongside every note letter for music theory and sight-singing
• Beautifully simple interface — no clutter, no setup, no instrument selection needed
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.
