Clinical-grade cardiac
monitoring.

Medically regulated

ECG — Atrial Fibrillation Detection

Take a 30-second ECG directly from your i bio Band. Detects atrial fibrillation (AFib) — the most common serious heart arrhythmia — with clinical sensitivity. Results are stored and shareable with your doctor.

Not intended for users with known arrhythmias other than AFib, or users under 22.

Background monitoring

Irregular Heart Rhythm Notifications

i bio continuously monitors your heart rhythm in the background — 24/7 — and sends an alert if it detects a rhythm that may suggest atrial fibrillation, even when you haven't triggered a manual ECG.

Not intended for users with known atrial fibrillation or users under 22.

Nightly measurement

Heart Rate Variability (HRV)

HRV is the most powerful predictor of recovery, stress, and overall readiness. i bio measures HRV during sleep when readings are most accurate — and tracks your 30, 60, and 90-day baselines over time.

Continuous estimation

Blood Pressure Insights (Beta)

Using pulse transit time and your biometric patterns, i bio provides blood pressure trend insights throughout the day — without a cuff. Not a medical device, but a powerful wellness signal for long-term tracking.

Not a medical device. Not for users with known hypertension or pregnancy.

Your heart. Watched
every second.
