Music Note Identifier: Tonarly

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.

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.
