Chordical: Guitar Tuner

Pluck a string and watch your tone rise as a field of light. Precise, fast pitch detection meets a mesmerizing real-time 3D visualizer. Tune by eye and ear.

Chordical is a guitar tuner with a soul. Pluck a string and your sound blooms into a living 3D visualizer — a real-time waterfall of light that rises and ripples with your tone — while a precise needle and cents readout guide you to perfect pitch.

Built on a fast, accurate pitch-detection engine (native YIN DSP), Chordical locks onto your note instantly and tells you exactly how sharp or flat you are, down to the cent.

FEATURES • Real-time 3D audio visualizer that reacts to every note you play • Fast, accurate pitch detection with a clear cents readout • Large, easy-to-read note + frequency display • Color-coded tuning meter — red to amber to green as you home in • Adjustable input sensitivity so the visuals match your room and your playing • Drag to orbit the 3D scene; your view and settings are remembered • Soft, calm neumorphic design that stays out of your way • Tune any string by ear — standard tuning, drop tunings, and every note in between

PRIVATE BY DESIGN All audio is processed on your device in real time. Your sound never leaves your phone, and nothing is recorded or uploaded.

Whether you play acoustic, electric, bass, or ukulele, Chordical turns tuning from a chore into a moment. Plug in your ears, watch the light, and play in tune.
