Oura Ring 4 Review: I Finally Found a Fitness Tracker I Never Want to Take Off

The Oura Ring 4 delivers a more subtle and consistent approach to health tracking, focusing on long-term insights rather than overwhelming you with data. Its biggest strength lies in how effortlessly it fits into daily life, especially when compared to traditional wearables that can feel intrusive. Over time, it builds a clearer picture of your habits, helping you better understand how your body responds to sleep, activity, and recovery.

• Comfortable Design: The lightweight titanium build makes it easy to wear all day and, more importantly, through the night without discomfort
• Sleep Tracking: Offers detailed insights into sleep stages, recovery, HRV, and body temperature with clear, easy-to-understand explanations
• Simplified Insights: Breaks down complex biometric data into intuitive scores like Readiness and activity trends for everyday use
• Activity Tracking: Automatically detects workouts and daily movement, supported by heart rate zones and detailed session tracking
• App Experience: Adds depth with features like Timeline, meditation content, AI guidance, and evolving experimental tools that personalise the experience

The Oura Ring 4 comes in six shades in India: Black, Gold, Sliver, Stealth Black, Rose Gold, and Brushed Silver. While all six shades are made of titanium, the Black and Silver models cost Rs 10,000 less than the other four, although it comes down to aesthetic differences rather than material. The Ring 4 is water resistant, so I didn't have to take it off during showers, while the durable material is resistant to scratches.

At first, I wasn't too sure about the flashy gold finish but in hindsight it is perfect for occasions and is no different from the others for daily use. I have used the Ultrahuman Ring AIR in the past, and the lack of a bump on the Oura Ring 4 makes it extremely comfortable. Oura also sends a size kit from sizes 4 to 15 to ensure the perfect fit. While the sizing kit costs Rs 999, the amount is adjusted after you purchase the smart ring.

Overall, I'd give the Oura Ring 4 full marks in terms of appeal, comfort, and durability, although the tougher ceramic version of the Ring 4 hasn't been unveiled in India.

Sleep tracking is where the Ring 4 really stood out for me. Unlike a smartwatch that you constantly feel on your wrist, the ring is so subtle that I often forgot I was wearing it. That alone made it far easier to wear consistently through the night.

What I appreciated the most is how it goes beyond just tracking how long you sleep. Each morning, I could see a detailed breakdown of my sleep stages, along with insights into my resting heart rate, HRV, and body temperature. More importantly, the app explains all of this in a way that actually makes sense. Instead of overwhelming me with numbers, it tells me how well I slept and what to expect from the day ahead.

There were days when the app suggested I take it easy, and looking back at the data, it usually lined up with how I felt. It also adjusts daily activity targets based on your sleep, which made the whole experience feel connected rather than isolated. Over time, I started noticing patterns in my sleep, especially around consistency and recovery, and that made it easier to understand what was affecting my rest.

The Readiness score became something I checked almost every morning. It pulls everything together and gives you a simple snapshot of how your body is doing. I found myself relying on it more than I expected, especially on days when I was unsure whether to push harder or slow things down.

Outside of sleep, the Ring 4 quietly builds a broader picture of your overall health. Activity tracking felt equally thoughtful.

The ring automatically picked up a wide range of activities, but what I liked most was how it accounted for smaller movements throughout the day. Even on days when I was not actively working out, it still captured how much I was moving overall. Since I spend long hours sitting, the reminders to move felt well timed and not intrusive, and they actually helped me stay a bit more active.

The Oura Ring 4 continuously tracks your heart rate throughout the day, regardless of what you're doing. For supported workouts, it adds more context by breaking your session down into heart rate zones, giving you a clearer sense of how intense your effort actually was. You also get a detailed heart rate graph across the duration of the workout, along with your average heart rate, which makes it easier to reflect on how hard you pushed yourself.

The app also includes an Explore section with guided meditation content, which I occasionally found helpful when trying to wind down. There is also Oura Labs, where the company is experimenting with new ideas. I tried the conversational version of the Oura Advisor, which presents insights in a chat-like format. It still feels a bit early, but it is an interesting direction. I also found myself opening the app just to log meals, as Oura suggests ways to balance my diet with more protein and vegetables. The AI does a surprisingly good job of recognizing dishes from photos. It is not something I relied on heavily, but it hints at where the platform could go in the future.

Over time, features like Timeline made the experience feel more personal, letting me tag meals, workouts, and even stressful moments, and gradually build a clearer picture of how my daily habits actually affected how I felt.

Oura promises up to 8 days of battery life on a single charge, and in my experience these figures are more or less accurate. However, battery life will vary depending on your ring size. I got around six days of battery life with my size 9 ring. I found the biggest drop off in battery life at night, which appears to be a result of the ring working overtime to monitor your sleep cycles, heart rate variability, blood oxygen levels, and body temperature, all of which require continuous tracking and higher sensor activity. Its continuous temperature tracking also offers valuable insights for detecting hormonal changes associated with ovulation and pregnancy.

The Oura Ring 4 is accompanied by a premium metal charging dock. The ring aligns seamlessly with the pill-shaped LED charging dock, reaching a full charge in just over 100 minutes. Oura does send charging notifications when you have little under a day of battery life.

The Oura Ring 4 is priced at Rs 28,900 for the Black and Silver models. Moreover, the Gold, Rose Gold, Stealth Black, and Brushed Silver variants will set you back Rs 39,900. You will also have to pay a monthly fee of Rs 599 for the subscription after the first month.

In my opinion, the subscription is where the real value of the Oura Ring 4 comes through. The insights, guidance, and small nudges genuinely make a difference over time, making the Rs 599 monthly fee feel justified. That said, the upfront price of the ring itself is definitely on the higher side, which makes it a more considered purchase rather than an easy recommendation.

After spending a few weeks with the Oura Ring 4, it ended up changing my habits more than I expected. As someone who struggles with consistent sleep and tends to rely on naps through the day, having that constant feedback and gentle push to improve my routine actually made a difference. I found myself paying more attention to when I sleep, how well I recover, and whether I should be pushing myself or slowing down.

A big part of that comes down to comfort. I have never enjoyed wearing a watch or band to bed, and that has always been a barrier with traditional wearables. The Ring 4 solves that completely. It is easy to forget you are wearing it, which makes it far easier to stay consistent and get meaningful data night after night.

The sleep tracking, in particular, is where it truly shines. The insights feel accurate, easy to understand, and most importantly, useful. Combined with the broader health metrics and readiness insights, it gives you a clearer sense of how your body is responding to your daily habits without overwhelming you.

Activity tracking, on the other hand, is good but not quite on par with a full smartwatch. That said, considering the size, it is understandable why it cannot offer the same level of depth. What it does provide still feels reliable enough for everyday use.

At the end of the day, the Oura Ring 4 works best as a tool for awareness rather than just tracking. If you are someone who struggles with sleep or simply wants to build a healthier daily routine, it is an easy recommendation despite the higher upfront cost.
