Luna, a new-age health-tech company approaching the core problem of unlocking human potential, differently, today announces the global launch of Luna 2.0 af IFA2025 its next gen smart ring which comes equipped with the new LifeOS, a powerful intelligence layer that transforms biometrics into adaptive real-time guidance. Luna 2.0 is finally available worldwide at Luna for $300/£300 and $329/£329 with surge charging case. Pre-orders have come from more than 70 countries, and Amazon availability rolling out next month.
Introducing LifeOS: More than a health tracker, a living intelligence
LifeOS is designed to decode how the body, mind, and environment interact, going beyond raw data. It is the most data trained AI wearable intelligence integrating circadian rhythm science, biomarker signals, personal habits, and contextual data (like chat patterns and daily routines) to create a dynamic intelligence layer.
- Circadian alignment: LifeOS learns an individual’s internal body clock to guide daily peak performance.
- Contextual intelligence: It adapts to a user’s lifestyle, habits, and environment.
- Open & extensible: Built as an open-source plug, LifeOS is designed to ingest additional data streams over time.
- Trained at scale: LifeOS is powered by over 1 billion sleep events, making it the most extensively trained intelligence layer across rings.
- 21+ day battery life: Powered by a redesigned charging case, making Luna one of the longest-lasting smart rings available.
Smarter wellness, backed by AI:
- AI-driven health scoring: Luna Ring 2.0 delivers real-time sleep, readiness, and activity scores. These scores are powered by an upgraded Luna AI engine that analyses physiological patterns to offer personalised recommendations on sleep quality, stress resilience, and recovery.
- Luna AI 2.0 assistant: Building on user feedback, the new AI system is more contextual and conversational, offering proactive suggestions for sleep optimisation, movement patterns, and energy management, bridging the gap between raw data and real-life wellness decisions.
- Comprehensive activity logging: The ring supports advanced workout tracking, including heart rate zones, effort levels, calories burned, and more across structured activities such as running, cycling, walking, and freestyle sessions.
- Fertility tracking: Luna detects physiological shifts in an individual’s cycle like temperature and recovery to predict phases and personalise wellness insights.
- Manage stress: Luna spots signs of stress through heart rate, recovery trends, and temperature shifts so patterns can be identified and action taken.
- Body training: Luna tracks daily effort and recovery to guide smarter workouts, helping build fitness without burning out.
- Enhanced sleep analytics: Luna 2.0 now provides deeper sleep analysis with expanded insights into latency, efficiency, circadian rhythm alignment, sleep cycles, movement disturbances, and respiratory performance during rest. This demonstrates how quality of sleep affects wellbeing.
Global Rollout and Momentum
Luna 2.0 has had pre-orders across 70+ countries. Retail and distributor prescence is being established across the world for faster delivery and service. Unveiled at CES, 2025 as a first time concept, bringing Luna 2.0 to the global tech stage for the first time at IFA Berlin is an exciting step for Luna as Europe is a key focus market.
“Luna 2.0 represents a step-change in what a smart ring can do,” said Amit Khatri, Founder of Luna. “With LifeOS, we’re moving beyond passive health tracking into an era where your ring actively helps you make better decisions for performance, recovery, and long-term health.”
