THE SCIENCE
Your heart doesn't
take days off.
Neither does NURBLOX.
Hospital-grade blood pressure monitoring, ECG detection, and 24/7 heart health insights — all from a watch designed for real life. No cuffs. No clinics. No guesswork.
Not a fitness tracker.
A clinical instrument.
NURBLOX TENGRI™ is built on the same sensor principles used in hospital-grade cardiovascular monitoring — miniaturised onto your wrist so the data that matters is always with you.
Blood Pressure Sensor
Cuff-free pressure monitoring.
Continuous. Accurate. Silent.
Traditional cuffs interrupt your day and only capture a snapshot in time. NURBLOX uses photoplethysmography (PPG) and pulse transit time algorithms to continuously track systolic and diastolic pressure — with clinical-level accuracy validated in independent studies.
High blood pressure has no symptoms until it's too late. NURBLOX catches the trend before it becomes a crisis — storing 30 days of readings your doctor can actually use.
Atrial fibrillation detection.
Before symptoms appear.
Atrial fibrillation (AFib) is a leading cause of stroke in adults over 55 — and most people don't know they have it. NURBLOX's single-lead ECG sensor records your heart's electrical activity directly from your wrist, flagging irregular rhythms the moment they occur.
A 30-second reading. A potentially life-changing alert. Share your ECG report with your cardiologist at your next appointment.
ECG / Heart Rhythm
Sleep Monitoring
Poor sleep is a cardiovascular risk.
Now you can measure it.
Sleep deprivation elevates blood pressure, increases cortisol, and accelerates heart disease. NURBLOX tracks your sleep stages throughout the night — light, deep, and REM — and shows you exactly where your rest is falling short.
Wake up with a simple overnight health score and clear recommendations. Better sleep is the most underrated cardiovascular intervention available.
Movement as medicine.
Tracked at your pace.
For adults over 55, consistent gentle movement is one of the most powerful tools for managing blood pressure and reducing cardiovascular risk. NURBLOX tracks your steps, active minutes, and calories — celebrating every walk, garden session, and staircase.
Activity coaching that meets you where you are — not where a fitness app thinks you should be.
