Own Your Health. Master Your Life.
Zentra translates your body's hidden signals into three simple scores, empowering you to improve your well-being, one day at a time.
Your Health, Simplified.
We analyze thousands of data points from your body and distill them into three intuitive scores, so you know exactly where you stand and what to do next.
Readiness
A holistic picture of your health. Are you ready to push your limits, or is it a day for recovery?
Sleep
Understand the quality and duration of your rest. Optimize your sleep for peak daytime performance.
Activity
Balance your activity and rest. Learn how your movement impacts your overall well-being.
Unmatched Accuracy, From Your Finger.
Your finger provides a more accurate reading of your heart rate and body temperature than your wrist. Zentra's advanced sensors capture your body's signals with research-grade precision, day and night.
Advanced Sensor Suite
Infrared, Red, and Green LEDs measure heart rate, HRV, and blood oxygen.
Precise Temperature Sensing
Tracks temperature changes as small as 0.1°C to reveal trends.
Less screen time. More life.
Zentra is designed to be worn 24/7, providing insights without the constant notifications and distractions of a smartwatch. It's health tracking that blends into your life, so you can focus on living it.
