🧠 Features and Sensors – What Does It Actually Do?

The Oura Ring Gen 3 offers advanced metrics powered by infrared sensors, a gyroscope, and a temperature sensor.

✅ Key Features:

You can access all data through the Oura mobile app (iOS & Android) with beautiful graphs, insights, and recommendations.

📱 App Experience: Intuitive and Data-Rich

The Oura App is one of its biggest strengths.
It’s divided into three main categories:

• Sleep

• Readiness

• Activity

Each section comes with daily scores out of 100, allowing you to see trends and understand your body better.

You also get:

• Guided meditations

• Period prediction for women

• Daily wellness insights

🌙 Sleep Tracking Accuracy – Better Than Smartwatches?

Sleep tracking is where Oura truly shines.
It uses heart rate + temperature + movement to give very accurate sleep stages.

Compared to Fitbit & Apple Watch:

• Oura is more accurate in detecting REM and Deep Sleep

• It tracks resting heart rate trends better over time

• Battery lasts longer, so no sleep interruption

---

❤️‍🔥 Health Insights: Readiness Score & Recovery

Oura gives you a daily Readiness Score, which combines:

• Sleep quality

• Resting heart rate

• HRV

• Body temperature

• Previous day’s activity

If you’re overtraining, stressed, or getting sick, your Readiness Score drops and the app will advise you to take it easy.

It’s like having a personal health coach in your pocket—with no buzzing notifications!

---

🔋 Battery Life: 4–7 Days of Use

A full charge takes around 20–80 minutes, and it lasts 4–7 days depending on usage.

Unlike smartwatches, which need daily charging, you can sleep with Oura all week before charging.

---

🧪 Accuracy: Is the Data Reliable?

Most studies and reviews show Oura is very accurate for:

• Sleep stage tracking

• Resting heart rate

• Body temperature trends

But it’s not a full fitness tracker, meaning:

• Step count is less accurate

• No GPS or workout tracking

If you’re a pro athlete or runner, you may still need a smartwatch like Garmin or Apple Watch for activity-specific metrics.
