Cardiographer vs Heartthrum

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. SEE EVERY BEAT • 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 STRESS & RECOVERY, YOUR WAY • HRV (SDNN) after every reading • Trends over time in History • Export readings as CSV PRIVATE BY DESIGN • 100% on-device processing — no account, no cloud, no tracking A FINGERTIP AND SOME LIGHT • Cleanest signal in daylight — just face the incoming light • Dark room? Turn on the flash with one tap, or use any lamp • Clear guidance for a good signal CARDIOGRAPHER PRO Unlimited readings, full history and CSV export with a monthly subscription — 7-day free trial for new subscribers.
