Before buying, measure your finger circumference or use the included sizing kit to pick the right size for accurate sensor contact.

How accurate are the AutrefoisElf sensors for daily health tracking?

The Gen 3 uses a high‑precision optical sensor to record heart rate and blood oxygen trends and combines motion data for step counting. It’s optimized for daily monitoring and fitness activities, giving useful trends rather than clinical diagnostics.

• Continuous heart rate monitoring during rest and activity.
• Blood oxygen (SpO2) spot checks and trend tracking.
• Accelerometer-based step, distance and calorie estimates.
• Improved sensor contact when the ring fits snugly per the sizing chart.

What sleep and recovery information will I see in the app?

The ring automatically logs sleep stages including deep, light and REM, plus wake episodes and total duration. The app combines those metrics into a readiness score to help you plan intensity for the day and identify irregular sleep patterns over time.

• Automatic sleep start/end detection with stage breakdowns.
• Readiness score based on sleep quality and recovery metrics.
• Historical charts to spot trends across nights and weeks.
• Customizable sleep goals and quiet notification scheduling.

Can I use the ring for workouts, swimming and hands‑free photos?

Yes — the Gen 3 supports 139+ sports modes including running, cycling, yoga and swimming, and carries an IP68 rating suitable for showers and pool swims. It also functions as a remote shutter for your phone camera so you can capture group shots or solo training photos without touching your device.

• 139+ activity modes with workout summaries and calorie estimates.
• IP68 waterproof design for swimming and daily water exposure.
• Remote shutter control for phone cameras via Bluetooth.
• Workout history syncs to the free app — no monthly fee required.

How long does the battery last and how does charging work?

A single hour of charging delivers around 3–5 days of active use (5–7 days on standby), depending on how frequently sensors and notifications are used. The included charger is compact for travel and the app will notify you when battery is low.

• Quick 1‑hour charge time for everyday readiness.
• Typical active use: 3–5 days; standby: 5–7 days.
• Battery level visible in the companion app and on the device status.
• Designed for daily wear with water exposure in mind.

Who is this for? The AutrefoisElf Smart Ring Gen 3 suits people who want an unobtrusive wearable that tracks daily activity, sleep and basic physiological trends without monthly fees. It’s aimed at fitness enthusiasts who prefer a minimal profile over a wrist display, commuters and travelers who need an IP68 waterproof option, and anyone seeking straightforward readiness and sleep insights. Make sure to measure your finger or use the sizing kit to select the correct size (available in 6–14) for reliable sensor contact and comfortable all‑day wear.
