The pioneer of the smart ring category has officially made its grand entrance into the Indian market. Following its global success, the Oura Ring 4 is now available in India, bringing a refined, all-titanium design and a suite of “research-grade” sensors that promise to turn subtle body signals into actionable health insights.
Smart Sensing: Accuracy That Adapts
The core of the Oura Ring 4 is the new Smart Sensing technology. Unlike older wearables that use a “one size fits all” approach to data collection, the Ring 4 features a sensing platform that dynamically adjusts based on your unique finger shape, skin tone, and real-time activity. With 18 signal pathways (more than double the previous generation), the ring can maintain high-fidelity data even if it rotates slightly on your finger during sleep.
This increased accuracy powers the new Advanced Sleep Staging algorithm. By comparing heart rate, movement, and temperature trends against clinical polysomnography (sleep lab) data, Oura now offers a 79% accuracy rate in identifying Deep, REM, and Light sleep stages—one of the highest in the consumer wearable industry.
New Frontiers: Metabolic and Heart Health
For 2026, Oura has expanded beyond just “rest and recovery” to include:
-
Metabolic Tracking: By monitoring temperature trends and activity-induced strain, the app now provides insights into your metabolic health, helping users understand how their late-night meals or stress levels impact their body’s internal balance.
-
Cardiovascular Age & Capacity: Using the PPG sensors, the ring estimates your arterial stiffness and VO2 Max, giving you a “heart age” compared to your chronological age.
-
Women’s Health: Integration with apps like Natural Cycles allows for 94% accurate ovulation detection based on precise finger-temperature monitoring.
Oura Ring 4: Pricing and Finishes in India
| Finish Variant | Price (India) | Build Material |
| Silver & Black | ₹28,900 | Recycled Aerospace Titanium |
| Stealth & Brushed Silver | ₹39,900 | Diamond-like Carbon (DLC) Coating |

Note: Access to the full suite of data requires an Oura Membership, which is priced at ₹599 per month in India (the first month is included with the purchase).
Design and Endurance
The Ring 4 is remarkably lightweight, weighing between 3.3g and 5.2g depending on the size (sizes 4–15 are available). The interior is now completely smooth with recessed sensors, eliminating the “bumps” found on the Gen 3 model.
It boasts a battery life of up to 8 days and is water-resistant up to 100 meters, making it safe for swimming, saunas, and intense workouts. With its sleek, jewelry-like aesthetic, the Oura Ring 4 is positioned as the ultimate “invisible” health companion for those who want flagship-level tracking without the distractions of a smartwatch screen.
