Black Friday Deal: Luna 2.0 smart ring with surge charger with 20% discount

The original price of £299 has been slashed to £239.20 using code BFS20 from now until 28th November so you’d better be quick.

The 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.

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.

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.

It also provids fertility tracking: Luna detects physiological shifts in an individual’s cycle like temperature and recovery to predict phases and personalise wellness insights.

Luna spots signs of stress through heart rate, recovery trends, and temperature shifts so patterns can be identified and action taken.

Also it can help with body training: Luna tracks daily effort and recovery to guide smarter workouts, helping build fitness without burning out; as well as 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.

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.
