Product details

Meet the Oura Ring 4 Stealth, a refined all-titanium smart ring designed for everyday wear and deeper personal insights. The updated design is powered by Smart Sensing, a platform that adapts to you and quietly collects data that covers sleep, activity, readiness, heart health indicators, stress patterns, metabolic signals, and women’s health metrics. With up to 8 days of battery life and no screens or vibrations to distract you, it’s easy to wear from morning routines to evening plans.

Real-world use cases

Imagine waking up with a sense of rhythm in your routine. You can review sleep patterns after a late workout, notice how activity levels align with daily energy, and observe recurring cycles in stress or menstrual signals. The data is presented as trends and insights, helping you understand patterns over time without promising specific results.

  • Sleep optimization insights: track duration, sleep stages, and nightly recovery
  • Activity patterns: monitor steps, active minutes, and recovery windows
  • Well-being awareness: explore stress, heart rate variability, and menstrual health signals
  • Convenience: wear without attention and sync with your phone for easy access

Fit and value

With multi-ring support, you can switch finishes in the app if you own more than one Oura Ring 4 style. A sizing kit helps you confirm fit before you buy, ensuring comfort across days of wear. The ring is designed for daily life—whether you’re at work, on the go, or winding down at home.
