How accurate is the AutrefoisElf ring for daily health metrics?

The Gen 3 model uses refined optical sensors to record continuous heart rate, blood oxygen and stress-related variability data. While it provides actionable trend insights and day-to-day comparisons, it is intended for general wellness tracking rather than medical diagnostics.

• High-precision optical sensors for heart rate and SpO2 trends
• 24/7 continuous heart rate monitoring
• Stress score derived from HRV patterns, not a medical diagnosis
• Data accessible anytime in the free AutrefoisElf app

What sleep details does the ring capture and how does that help?

The ring automatically records sleep duration and stages—deep sleep, light sleep, REM and wake periods—so you can spot patterns that affect energy and recovery. It also calculates a readiness score based on sleep and overnight recovery to help you plan activity and rest.

• Automatic detection of sleep start, end and interruptions
• Breakdown of REM, deep and light sleep stages
• Readiness score summarizes recovery and sleep quality
• Nightly reports in-app for trend tracking over weeks

Which fitness features and sports modes are supported?

The ring covers daily activity tracking—steps, distance and calories—and supports 139+ sports modes for focused workouts like running, cycling, yoga and swimming. It’s IP68 waterproof, so you can keep it on during swims and in the rain.

• Step, distance and calorie counts for everyday activity
• 139+ sports modes including swimming and cycling
• IP68 rating allows showering and pool use
• Remote shutter function for hands-free photos

How long does the battery last and what maintenance does the ring need?

A one-hour charge provides about 3–5 days of active use and 5–7 days on standby, depending on tracking intensity and connectivity. Routine upkeep is minimal: keep the contacts clean, follow the size guide before purchasing, and avoid harsh chemicals that may affect finish and sensors.

• 1-hour quick charge for multi-day use
• Typical active use: 3–5 days; standby: 5–7 days
• IP68 protection reduces need to remove for water exposure
