## Description

• Live pulse waveform at 240 Hz with beat-by-beat detail
• One averaged beat with the dicrotic notch labeled
• Heart rate (BPM) with signal-quality feedback

Cardiographer turns your iPhone's rear camera into a fingertip pulse reader. Cover the camera with a fingertip and watch your full pulse waveform at 240 samples per second — heart rate, the pulse shape with its dicrotic notch, and heart-rate variability for stress & recovery awareness. Everything is processed on your device; nothing is uploaded.
