WHAT YOU SEE • Note name, octave, and exact frequency in Hz • Cents deviation — how sharp or flat you are • Color-coded tuning: green (in tune), yellow (close), red (off) LIVE PITCH GRAPH Watch your pitch draw across the screen. Pinch to zoom, pan to explore, or enable Auto-Follow to stay centred on your current pitch. FOUR DETECTION ENGINES • CREPE (Neural Network) — highest accuracy, best for voice • YIN — fast and battery-friendly, great for single notes • ACF — lowest latency, ideal for loud clear signals • HPS — suited for instruments with strong harmonics RECORD & SHARE Capture your session as a WAV file.
