Oura has officially introduced its latest wearable, the Oura Ring 4, in India—marking the brand’s entry into one of the fastest-growing health and fitness tech markets. Although the device first debuted globally nearly two years ago, its arrival in India signals Oura’s intent to expand its footprint and compete in the premium wearable segment.
A Smart Ring Focused on Health and Recovery
The Oura Ring 4 continues the company’s core philosophy: delivering in-depth health tracking in a compact, unobtrusive form. Designed to be worn around the clock, the ring emphasizes sleep monitoring, recovery insights, and overall wellness tracking. It seamlessly connects to the Oura app via Bluetooth Low Energy (LE), ensuring efficient power consumption while maintaining constant data synchronization.
Minimalist Design, Maximum Comfort
In terms of design, the Oura Ring 4 maintains a clean and minimal aesthetic while improving durability. The device is crafted entirely from titanium, making it both lightweight and skin-friendly for all-day wear. It is also water-resistant up to 100 meters, adding to its versatility for daily use, including workouts and swimming.
The ring measures 7.90 mm in width and 2.8 mm in thickness, with a weight ranging between 3.3 grams and 5.2 grams depending on the size—ensuring a comfortable fit without compromising durability.
Smart Sensing Takes Center Stage
A key highlight of the Oura Ring 4 is its advanced Smart Sensing technology. This system combines refined algorithms with high-grade sensors to deliver more accurate and personalized health insights. According to the company, this technology has been validated by leading research institutions such as the University of Tokyo and the National University of Singapore.
This focus on accuracy positions the ring as more than just a fitness tracker—it becomes a comprehensive health monitoring tool.
Advanced Sensors for Deeper Insights
Under the hood, the Oura Ring 4 is equipped with an 18-path, multi-wavelength PPG (photoplethysmography) system. This advanced setup continuously monitors the body throughout the day and night, capturing key metrics such as:
- Resting heart rate
- Heart rate variability (HRV)
- Sleep stages and cycles
- Body temperature fluctuations
The device uses red and infrared LEDs to measure blood oxygen levels during sleep, while green and infrared LEDs track heart rate, HRV, and breathing patterns overnight.
Additionally, the ring includes an accelerometer to monitor movement and activity levels, along with a digital temperature sensor for detecting subtle physiological changes.
Battery Life and Charging
Battery performance is another strong point. The Oura Ring 4 offers up to eight days of usage on a single charge, depending on usage patterns. Charging time ranges between 20 and 80 minutes, and the device comes with its own proprietary charger for convenience.
Expanding Into India’s Wearable Market
With the launch of the Oura Ring 4 in India, Oura is stepping into a competitive yet rapidly expanding market driven by increasing health awareness and demand for smart wearables. Its focus on precision, comfort, and advanced analytics could appeal to users looking for a more discreet alternative to traditional smartwatches.
As wearable technology continues to evolve, the Oura Ring 4 represents a shift toward smaller, smarter, and more personalized health devices—bringing powerful insights right to your fingertips.
