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.
