Luna has officially launched Luna 2.0 at IFA 2025, aiming to compete directly with the popular Oura ring. This innovative smart ring is powered by a groundbreaking operating system named LifeOS, which promises to “transform biometrics into adaptive real-time guidance.” Like many contemporary tech products, the Luna 2.0 is rich with AI-driven features, including health scoring and the enhanced Luna AI 2.0 assistant. Additionally, a redesigned charging case allows for an impressive battery life that extends to over 21 days.
The Luna 2.0 Smart Ring Features New LifeOS
At the core of the Luna 2.0 smart ring is LifeOS, touted as the most “data-trained AI wearable intelligence.” This system incorporates principles from circadian rhythm science, biomarker signals, personal habits, and contextual information to create a “dynamic intelligence layer.” According to Luna, LifeOS benefits from over a billion processed sleep events, establishing it as the most trained intelligence layer available in smart rings today.
LifeOS adapts to the user’s internal body clock to enhance daily performance. It learns from the user’s lifestyle, habits, and surroundings, allowing for personalized recommendations. The built-in Luna AI 2.0 assistant is now more contextual and conversational, providing real-time suggestions for optimizing sleep, movement, and energy levels. This capability helps bridge the gap between raw health data and practical wellness decisions.
The Smart Ring is 5 ATM Water-Resistant
The Luna 2.0 ring goes beyond typical fitness tracking by offering real-time metrics for sleep, readiness, and activity. This is facilitated by the innovative Luna Engine, which assesses physiological patterns and generates personalized recommendations related to sleep quality, stress resilience, and recovery. In-depth sleep analysis features include latency, sleep efficiency, circadian rhythm dynamics, sleep cycles, movement disturbances, and respiratory performance during rest.
When it comes to workouts, the Luna 2.0 offers advanced tracking capabilities, covering various activities like running, cycling, walking, and freestyle workouts. It can monitor stress levels based on heart rate changes, recovery trends, and temperature fluctuations. Furthermore, the ring can identify physiological changes tied to an individual’s cycle, delivering tailored wellness insights based on those shifts.
Durability is a hallmark of the Luna 2.0, featuring a robust titanium body and a 5 ATM water-resistance rating. In terms of battery life, the smart ring lasts up to five days on a single charge, further extended to over 21 days thanks to the new surge charging case.
Price and Availability
The Luna 2.0 is priced at approximately $300, or $329 when bundled with the innovative surge charging case. It will be available for purchase directly through the Luna website, with listings on Amazon set to launch next month.
