Before ordering, measure your finger circumference and consult the brand size chart to ensure accurate sensor contact and a comfortable fit.

How accurate are the heart rate and blood oxygen readings?

The ring uses a high-precision optical sensor to sample pulse and blood oxygen levels at regular intervals throughout the day and night. While convenient for trend monitoring and lifestyle adjustments, readings are intended for personal tracking rather than medical diagnosis.

• Continuous heart rate sampling with periodic updates for resting and active states
• SpO2 monitoring during rest and sleep profiles
• Data displayed in the free AutrefoisElf app, no subscription required

What sleep and recovery information will I see each morning?

The ring automatically records sleep duration and breaks sleep into light, deep and REM phases to give a clearer picture of nightly rest. A readiness or recovery score aggregates sleep quality and physiological markers to help you plan activity and rest.

• Automatic detection of sleep onset, awakenings and sleep stages
• Sleep duration and efficiency metrics visible in the app
• Daily readiness score based on sleep and overnight recovery signals

Can I use the ring for workouts and everyday activity tracking?

Yes — the Gen 3 supports over 139 sport modes and logs steps, distance and calorie burn for both casual activity and structured workouts. It also doubles as a remote shutter for hands-free photos and is rated for swimming and showering thanks to its IP68 waterproofing.

• Step counter, distance estimates and calorie tracking for daily use
• 139+ sports modes including running, cycling, yoga and swimming
• Remote shutter for phone camera control and practical, hands-free use

How long does the battery last and how durable is the ring?

Fast charging gives the ring a full active cycle after about one hour of charging, delivering roughly 3–5 days of typical use and up to 5–7 days on standby. The IP68 rating protects against dust and water immersion, so it stays on during showers and swims.

• One-hour charge time for several days of active monitoring
• IP68 waterproof rating suitable for showering and swimming
• Durable materials and low-profile shape built for daily wear

Who is this for: The AutrefoisElf Smart Ring Gen 3 is aimed at people who want unobtrusive, continuous health and activity monitoring without subscription fees — ideal for fitness enthusiasts, shift workers tracking sleep, or anyone seeking a small, stylish tracker that blends with jewelry. If you prefer wrist wearables or require clinical-grade measurements, consider that this device is optimized for lifestyle insights rather than medical diagnostics.
