About NAVA Smart Rings

NAVA is an Israeli company that develops and markets smart rings. Our flagship product, the NAVA Pro, is the world’s first smart ring with a medical-grade ECG sensor, offering advanced, continuous, and highly accurate monitoring of vital health metrics directly from the finger — a superior measurement point compared to other wearables. The ring is certified by CE, FCC, and IC, and has completed the first phase of testing toward FDA 510(k) Class II clearance. Audit files are currently being finalized for submission. The ring was benchmarked against an FDA-approved medical device (model VC001), demonstrating impressive accuracy: heart rate measurements showed a 2.78 bpm RMS deviation (~98% accuracy), and blood oxygen saturation (SpO₂) showed a 1.91% RMS deviation (~98% accuracy). Testing followed key standards such as ISO 80601 and IEC 60601-2-47. The ECG algorithm is based on FDA-approved third-party technology, providing clinically validated performance. The NAVA ring works independently throughout the day thanks to built-in memory that stores data for up to 7 days. It syncs with both iOS and Android, has a 4–7 day battery life, and is crafted from titanium with a hypoallergenic PVD coating. It comes in four colors and sizes 6–13 (US). Radiation levels are extremely low due to short-range Bluetooth Low Energy (BLE). The NAVA app is the most advanced in the wearable space, integrating multiple data sources simultaneously to deliver highly personalized, AI-powered insights for each individual user.
