Let’s admit it: Smartwatches are annoying.
They vibrate during meetings. They light up in a dark movie theater. And trying to sleep with a bulky chunk of metal and rubber strapped to your wrist is the opposite of "restful."
If you read our previous deep dive on The 'Zombie Effect', you know that tracking your sleep (specifically HRV and Deep Sleep) is the first step to fixing your chronic fatigue. But you can't track what you don't wear.
Enter the Smart Ring War of 2025.
For years, Oura was the undisputed king. They invented the category. But now, the giant has awoken. Samsung has entered the ring (pun intended) with the Galaxy Ring, promising to crush the competition with its massive ecosystem.
So, which one deserves a spot on your finger? Is the Oura Ring 4 still the gold standard, or has Samsung stolen the crown?
We spent 30 days testing both. One on the left hand, one on the right. No press releases, no marketing hype. Just raw data. Here is the verdict.
Round 1: Design & "Invisibility" (The Comfort Test)
The whole point of a smart ring is that you forget you are wearing it.
The Oura Ring 4
Oura has perfected the art of making "tech" look like "jewelry." The Gen 4 model is fully titanium, incredibly lightweight, and comes in sleek finishes like Stealth (matte black) and Gold.
- The Feel: It has slightly raised sensors on the inside. You feel them for the first 10 minutes, and then they disappear. It feels premium, dense, and expensive.
The Samsung Galaxy Ring
Samsung went for a concave design (slightly curved inward) to prevent scratches. It looks futuristic, but arguably less "classic" than the Oura.
- The Feel: It is lighter—almost too light. It feels a bit more "plasticky" compared to Oura’s dense titanium feel, even though both are durable.
ð Winner: Oura Ring 4.
If you want something that looks like a wedding band and pairs with a suit or a dress, Oura still holds the edge in aesthetics.
Round 2: The Data (Sleep & Health Tracking)
This is why you are spending $300+. Which one actually knows your body better?
Sleep Tracking Accuracy
Both rings use advanced photoplethysmography (PPG) sensors to track heart rate, respiratory rate, and movement.
- Oura: Their algorithm is legendary for a reason. In our testing, Oura consistently nailed the "latency" (how long it took to fall asleep). It also correctly identified those brief 2 a.m. wake-ups that you don't remember.
- Samsung: The Galaxy Ring leans heavily on Samsung’s "AI Health" engine. It is excellent at detecting naps (something Oura historically struggled with) and integrates snore detection if you have your phone nearby.
The "Morning Report"
- Oura Readiness Score: This is the metric that started the biohacking revolution. It combines your sleep, activity, and body stress into a single score (0-100). It is brutally honest. If you drank alcohol last night, Oura knows. It will tell you to take it easy.
- Samsung Energy Score: Samsung uses AI to give you a similar "Energy Score." It’s good, visual, and easy to understand, but it feels slightly more "generous" than Oura. Oura feels like a strict coach; Samsung feels like a supportive friend.
ð Winner: Tie.
For pure sleep data accuracy, Oura is still the benchmark. For AI integration and actionable tips, Samsung is catching up fast.
Round 3: The Ecosystem (The Deal Breaker)
Here is where the paths diverge. Your phone choice might make the decision for you.
The Samsung Galaxy Ring: The "Walled Garden"
Samsung is playing the Apple game.
- The Catch: The Galaxy Ring works best with a Samsung phone. It works okay with other Androids. It is a paperweight if you have an iPhone.
- The Magic: If you do have a Galaxy Watch, the Ring and Watch talk to each other. They switch sensors automatically to save battery. It’s seamless.
The Oura Ring 4: The Agnostic Player
Oura plays nice with everyone.
- Compatibility: It works perfectly on iOS (iPhone) and Android. It syncs with Apple Health, Google Fit, Strava, and Natural Cycles.
- Independence: You don't need a specific watch or phone brand.
ð Winner: Oura Ring 4 (for versatility).
Unless you are married to the Samsung ecosystem, Oura is the safer bet.
Round 4: The Elephant in the Room (The Subscription)
This is the most controversial part of this review.
Oura’s Business Model
You pay $299+ for the ring, AND you must pay $5.99/month for the membership.
Without the membership, the ring is useless. You only get basic scores. No detailed charts, no history, no insights.
- Is it worth it? Honestly? Yes. The data analysis you get for the price of a coffee is unmatched. But it stings to pay a subscription for hardware you already bought.
Samsung’s Business Model
You pay for the ring. That’s it.
Samsung (currently) does not charge a monthly subscription for its health features. You get the Energy Score, sleep tracking, and AI insights for free.
ð Winner: Samsung Galaxy Ring.
For the value-conscious buyer, zero subscription fees is a massive advantage. Over 3 years, Samsung saves you over $200.
Round 5: Unique "X-Factor" Features
Oura: Illness Detection
Oura is uncanny at predicting sickness. Often, your Body Temperature and HRV will shift 2 days before you feel a sore throat. The app will warn you: "Your readiness is low. Something is up." It’s a literal lifesaver.
Samsung: Gesture Control
Because it’s part of the Galaxy ecosystem, you can pinch your fingers (wearing the ring) to dismiss an alarm or take a photo on your Samsung phone. It’s a cool party trick, but is it biohacking? Not really.
The Verdict: Which One Should You Buy?
This is not a participation trophy. There is a right choice for you.
Buy the Oura Ring 4 IF:
- You use an iPhone. (This is the only choice).
- You are a serious Biohacker. You care about raw data accuracy, trend analysis, and illness detection.
- You want the best-looking ring. The finishes and form factor are still superior.
- You are willing to pay $6/month for elite-level data.
Buy the Samsung Galaxy Ring IF:
- You own a Samsung Phone. The integration is flawless.
- You hate subscriptions. You want to buy it once and own it forever.
- You want a lighter, more modern feel.
- You are a casual user who wants "good enough" data without the monthly tax.
Conclusion: Just Wear One.
Whether you choose Team Oura or Team Samsung, the victory is in the awareness.
Wearing a smart ring changes your psychology. When you see how that late-night pizza destroyed your Deep Sleep, you stop eating it. When you see how a walk boosts your HRV, you walk more.
These rings are not magic wands. They are mirrors. They show you the truth about your body. And in 2025, that truth is the most valuable asset you have.
