Oura Ring

💤 Sleep Monitoring

• Measures your sleep stages (light, deep, REM) and total sleep time.
• Tracks resting heart rate, heart rate variability (HRV), respiratory rate, and body temperature during sleep.
• Generates a Sleep Score that reflects the quality and efficiency of your sleep.

💪 Readiness & Recovery

• Combines key metrics like sleep quality, HRV, body temperature trends, and recent activity into a Readiness Score — an indicator of how prepared your body is for physical or mental strain.
• Helps you decide whether to push yourself or prioritise rest.

🏃 Activity Tracking

• Counts steps, calories burned, and general movement.
• Provides an Activity Score based on daily activity patterns, but doesn’t focus on detailed workout metrics like GPS pace or structured training metrics.

💓 Vital Signs & Physiological Signals

• Monitors heart rate, heart rate variability (HRV), respiratory rate, skin temperature, and blood oxygen (SpO2) — especially during sleep.
• Because the ring sits on your finger, some metrics can be more consistent than wrist‑worn devices.

📱 App & Insights

• All data syncs to the Oura app, where you can see daily scores, long‑term trends, and personalised guidance.
• Apps now offer AI‑personalised insights and routines to help improve sleep, stress, and activity habits.

🔋 Practical Info

• Battery lasts up to ~8 days on a charge.
• Water‑resistant (~100 m), comfortable, and comes in multiple styles and colours.
