Oura Ring 4 has officially launched in India, bringing the Finnish health technology company’s smart ring to the country for the first time. The wearable focuses on continuous health tracking, sleep analysis, and recovery insights, powered by Smart Sensing technology and research-grade sensors.
The ring, which debuted globally nearly two years ago, is now positioned for India’s growing health and fitness wearables market. It supports heart rate variability (HRV) tracking, Bluetooth Low Energy connectivity, and claims up to eight days of battery life on a single charge.
What Is the Oura Ring 4 and What Does It Track?
Oura Ring 4 is a compact, finger-worn health wearable designed to monitor key biometric indicators throughout the day and night. Unlike traditional smartwatches, it prioritizes passive tracking and long-term health insights over notifications or screens.
The ring continuously tracks:
- Resting heart rate
- Heart rate variability (HRV)
- Sleep stages and sleep duration
- Respiration rate during sleep
- Body temperature trends
- Blood oxygen levels during sleep
- Daily movement and activity levels
All data syncs with the Oura App using Bluetooth Low Energy (BLE), allowing users to view health insights and trends over time.
Oura Ring 4 Price in India and Availability Details
The Oura Ring 4 price in India starts at Rs. 28,900 for the Black and Silver variants. Premium finishes, including Brushed Silver, Rose Gold, and Stealth, are priced at Rs. 39,900.
The smart ring is available in 12 size options, ranging from size 4 to size 15. According to the company, sales begin March 18, with availability both online and across 100 Croma retail stores in India.
Oura also offers a monthly subscription priced at Rs. 599, which unlocks deeper health insights and enhanced tracking features within the app.
How Smart Sensing Technology Powers Health Insights
A key feature of the Oura Ring 4 is its Smart Sensing technology, which combines advanced algorithms with research-grade sensors to improve accuracy and personalization.
At its core is an 18-path multi-wavelength photoplethysmography (PPG) subsystem. This setup uses multiple sensors and LED wavelengths to capture biometric signals more consistently across different skin tones, finger sizes, and daily conditions.
According to the company, the ring’s accuracy has been validated by global research institutions, including the University of Tokyo and the National University of Singapore.
Sensors, LEDs, and What They Measure
The Oura Ring 4 uses a combination of sensors to collect health data around the clock:
- Red and infrared LEDs measure blood oxygen levels during sleep
- Green and infrared LEDs track heart rate and HRV
- Accelerometer monitors movement and activity patterns
- Digital temperature sensor detects changes in body temperature
This multi-sensor approach allows the ring to track both daytime activity and nighttime recovery without requiring user input.
Design, Build, and Comfort Factors
The Oura Ring 4 features a lightweight, non-allergenic all-titanium build designed for continuous wear. It measures 7.90mm in width and 2.8mm in thickness, with weight ranging from 3.3g to 5.2g, depending on size.
The ring offers up to 100 meters of water resistance, making it suitable for everyday use, workouts, and exposure to water. It ships with a size-specific proprietary charger, ensuring proper alignment and efficient charging.
Battery Life and Charging Expectations
Battery performance is a key claim of the Oura Ring 4. The company states the smart ring can deliver up to eight days of battery life on a single charge, depending on usage and tracking settings.
Charging time ranges between 20 and 80 minutes, based on the remaining battery level. The use of Bluetooth Low Energy helps reduce power consumption during data syncing.
What the Oura Ring 4 Launch Signals for India’s Wearables Market
With the Oura Ring 4 entering India, smart rings are moving beyond niche status and into mainstream health technology conversations. The focus on HRV tracking, sleep quality, and recovery metrics reflects growing consumer interest in long-term wellness data rather than just step counts.
As competition in the wearables space intensifies, the Oura Ring 4 positions itself as a data-driven, discreet alternative to wrist-based devices. Its India launch signals expanding demand for compact, sensor-heavy health wearables that prioritize accuracy and comfort.
