How accurate are the sensors for daily health tracking?

The Gen 3 uses a high-precision optical sensor to record heart rate, blood oxygen estimates and stress trends during rest and activity. While it’s not a medical device, the ring provides consistent, day-to-day trends to help you notice changes in recovery, effort and sleep quality.

• Continuous heart-rate sampling for resting and active periods
• Blood oxygen (SpO2) estimates to observe overnight and daytime patterns
• Stress-level algorithm based on heart-rate variability
• No subscription; all data accessible in the free AutrefoisElf app

Can I wear the ring during exercise and water activities?

Yes — the IP68 rating means it stands up to showers, swimming and sweat-filled workouts. The ring supports 139+ sport modes so it can log a variety of training types and record steps, distance and calories during sessions.

• Waterproof design suitable for swimming and showering
• Sports modes including running, cycling, yoga and swimming
• Step counting and calorie estimates for daily movement tracking
• Remote shutter function for hands-free photos during activities

How does sleep and recovery tracking work with the app?

Sleep is automatically logged each night with breakdowns for deep, light and REM phases plus wake times. The app generates a readiness or recovery score that summarizes your sleep and baseline stress to help you plan activity and rest.

• Automatic sleep detection—no manual input required
• Detailed stage reports: deep, light, REM and awake times
• Nightly recovery/readiness scoring to guide daily choices
• Exportable trends for weekly and monthly comparisons

What about battery life, sizing and setup?

Charging takes about one hour and yields 3–5 days of active use or 5–7 days in standby depending on settings and sensor use. Before ordering, measure finger circumference or use the AutrefoisElf sizing kit to pick the correct ring size for sensor accuracy and comfort.

• Quick 1-hour charge for multiple days of use
• Sizes 6–14; measure finger circumference for best fit
• Easy Bluetooth pairing with Android and iOS—no subscription fees
• Durable finish designed for everyday wear

Who this ring is for: The AutrefoisElf Smart Ring Gen 3 fits users who want unobtrusive, continuous tracking of sleep, recovery and activity without recurring app costs. It works well for fitness enthusiasts, shift workers trying to optimize rest, and anyone who prefers a discreet wearable instead of a wrist device. If you need medical-grade readings, consult a healthcare professional; for lifestyle and wellness trends, this ring delivers practical insights in a small, waterproof form.
