Building a world where every moment counts, while your Nava smart ring takes care of your health in the background.
We’re a health-tech company based in Israel, designing next-generation smart rings that bring accurate, medical-grade health insights into everyday life through seamless wearable technology.
We believe that to truly improve well-being and build better habits, health insights must fit naturally into daily life. That’s why we designed NAVA—our smart ring—to translate real-time body signals into simple, personalized guidance that empowers healthier routines without effort, stress, or disruption.
ECG Sensors
The only smart ring with ECG sensor and FDA-cleared ECG algorithm.
ECG sensors, combined with PPG, temperature, and motion sensors — for greater accuracy and deeper health insights.
The ring meets CE, FCC, IC standards and shows 98% accuracy in HR and SpO₂ compared to FDA-approved medical device VC001. The ring is not a medical device, but is designed to meet medical-grade standards for accurate wellness monitoring.
Curved Power
Inside, we use high-grade curved batteries designed specifically for rings. This ensures structural integrity and extends lifespan. Each battery supports up to 500 full charge cycles, maintaining long-term performance without degrading prematurely.
Our smart rings support wireless charging for a smoother, more durable experience. This method helps prevent physical wear over time and keeps the ring sealed, efficient, and user-friendly.
