The Luna Ring Gen 2, a titanium ring, is redefining personal health tracking with zero subscriptions and clinically backed AI.
Luna Ring Gen 2 is launching this July after winning the coveted CES Innovation Award 2025. This smart wearable by Noise, India’s leading smartwatch brand, blends advanced biometrics, real-time coaching, and user-driven features into a sleek, durable form. Designed to track over 70 health metrics, it promises to revolutionize how people interact with their own wellness.
Health tracking made invisible and accurate
Engineered from fighter jet-grade titanium, Luna Ring Gen 2 weighs just 3 to 5 grams and is water-resistant up to 50 meters. It monitors heart rate, SpO₂, sleep stages, recovery, stress, activity, and menstrual health—all from your finger.
It syncs automatically to the Luna app, which integrates seamlessly with both Apple Health and Google Fit. Every insight is presented in a clear, digestible format, helping users make meaningful decisions about their well-being.
More than data—meet LifeOS
The real power of Luna Ring Gen 2 comes from LifeOS, its proprietary AI system. It transforms raw biometrics into daily, actionable insights. For example, it might recommend a hydration boost after stress, or offer sleep-improvement tips based on heart rate variability.
Furthermore, LifeOS supports over 200 languages, and responds to real-time voice queries like, “How can I lower my stress score?” or “What’s my optimal sleep window tonight?”
In addition, every morning begins with a Daily Digest—a four-point health summary with specific recommendations. These features are designed not just for athletes or tech enthusiasts, but for everyday users who want practical wellness support.
Hardware upgrades you can actually feel
Several major improvements set the Gen 2 model apart. It includes a revamped charging case that stores power for up to 30 days, eliminating daily charging stress. The ring is now 10% slimmer, with improved performance thanks to faster onboard processing.
Also, Gen 2 offers expanded sizing, including Size 14, to improve fit and accessibility. Even more, the company provides over-the-air updates to both Gen 1 and Gen 2 users, ensuring ongoing performance enhancements.
No subscriptions—ever
Unlike many competing wearables, Luna Ring Gen 2 locks nothing behind a paywall. All features are unlocked with your purchase. There are no monthly fees, no gated insights, and no limitations based on tiered access.
As a result, users receive complete access to every insight, including sleep breakdowns, fertility windows, readiness scores, and training feedback. This approach reflects the company’s mission to keep health intelligence accessible and ethical.
Designed by experts, refined by real users
The development of Luna Ring Gen 2 involved clinical trials with Philips BioSensing Labs in Finland, ensuring 98.2% biometric accuracy. The company also partnered with elite sports labs at IIIT Hyderabad to refine physical performance metrics.
Importantly, over 2,000 pilot users helped shape the final product. Each development sprint includes the top two user requests. Recent updates include hydration reminders and step tracking nudges—both direct responses to community input.
In addition, the ring is used by professional athletes across India and the U.S., validating its performance in high-pressure real-world conditions.
