About
Hummy listens to your voice or instrument and shows you exactly what note you're playing — in real time.
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. Play back with a moving cursor that tracks your pitch note-by-note across the graph. Share directly from the app.
Adjustable mic sensitivity, fully on-device processing, no account required.
