The complete Chord, tuner and harmony companion for professional musicians.
Master your practice session, tune your instrument, and explore harmonic theory using pro-level visual tools.
Powered by a high-precision audio engine. Customize beat sounds, volume accents, and subdivisions. Visually track the tempo with the elegant pendulum design.
A fast, responsive, and highly accurate instrument tuner. Features an interactive seismograph-style waveform rendering that guides you to perfect pitch.
Explore chord relations, keys, and signatures in a highly interactive wheel. Highlight scale degrees, map modes (Dorian, Lydian, etc.) and learn chord families.
Visualize musical relationships geometrically. Study triadic voice leading and Neo-Riemannian paths (Parallel, Relative, Leading-Tone) with smooth transitions.
Exhaustive fretboard database. Visualize chords, scales, and triad inversions (Root, 1st, 2nd) across the entire guitar neck with complete note name and degree settings.
All processing runs locally on your iOS device. No analytics, no tracking, no user accounts. Your audio, microphone inputs, and settings never leave your phone.
Unlock three dimensions of musical practice.
Start the metronome with a tap. Adjust tempo by dragging the pendulum weight or entering precise values, and configure the acoustic click parameters.
Switch to the Circle or Tonnetz views to analyze chord modulations, key signatures, scale structures, and geometric movements.
Tune up using the seismograph dial, then pull up fretboard chord shapes, scale patterns, or triad inversions to bring theory to your fingers.
ChronoChord does not collect, store, or transmit any data. The microphone input is processed purely locally in real-time for tuning and is never stored or sent anywhere.
