The “Smart Ring Wars” have officially settled into a two-horse race. By early 2026, the wearable landscape has shifted dramatically from the wrist to the finger, and two titans stand above the rest: the Oura Ring 4 and the Samsung Galaxy Ring.
If you are reading this in 2026, you likely aren’t asking if you should get a smart ring, but which one deserves the real estate on your finger.
On one side, we have the Oura Ring 4, the refined fourth-generation specialist that released in late 2024, boasting a full titanium build and the most accurate sensors we’ve ever tested. On the other, the Samsung Galaxy Ring, a subscription-free powerhouse that integrates seamlessly into the Android ecosystem.
We’ve spent the last 18 months testing both rings through updates, feature drops, and daily wear. Here is the definitive, authoritative comparison to help you decide.

1. Design & Comfort: The “Flush” Factor
In 2026, comfort is king. Both rings have moved away from the bulky prototypes of the early 2020s, but they take drastically different approaches to how they sit on your finger.
Oura Ring 4: The Titanium Standard
The Oura Ring 4 (released Oct 2024) solved the biggest complaint of its predecessor: the sensors.
- Fully Flush Interior: Oura swapped the epoxy resin interior for medical-grade titanium. The sensors are now fully recessed, meaning there are no “bumps” digging into your finger.
- Size Range: With sizes ranging from 4 to 15, Oura fits a wider variety of hands, including smaller fingers that were previously left out of the smart ring market.
Samsung Galaxy Ring: The Concave Challenger
Samsung’s debut ring features a unique concave exterior design.
- Scratch Protection: The concave (inward curving) shape helps protect the surface from scratches—a smart move for a device that hits door handles daily.
- Epoxy Interior: Unlike the Oura 4, Samsung uses an epoxy (plastic-like) material on the inner band. While comfortable, long-term reviews from late 2025 suggest it is slightly more prone to wear than Oura’s all-metal body.
Winner: Oura Ring 4. The all-titanium build feels more premium, and the flush sensors offer superior 24/7 comfort.
2. Health & Sleep Tracking: Accuracy vs. Ecosystem
Oura’s “Smart Sensing” Platform
Oura remains the undisputed king of sleep staging. The Gen 4 introduction of “Smart Sensing” more than doubled the number of signal pathways (from 8 to 18).
- Automatic Adjustment: If the ring rotates on your finger (which it will), Oura 4 dynamically switches to the optimal sensor to keep data accurate.
- Metrics: It tracks SpO2, HRV, heart rate, and temperature trends with medical-grade precision. In 2026, Oura’s “Readiness Score” is still the metric all other wearables try to copy.
Samsung’s “Energy Score” & Galaxy AI
Samsung leans heavily on Galaxy AI.
- Energy Score: This aggregates sleep, activity, and heart rate into a single number, similar to Oura’s Readiness.
- Ecosystem Power: If you wear a Galaxy Watch and the Ring, Samsung Health automatically offloads tracking to the device with the better signal to save battery. This “handover” feature is a massive advantage for power users.
Winner: Oura Ring 4 for pure data accuracy; Samsung for integration with Galaxy Watches.
3. The Elephant in the Room: Subscriptions
This is arguably the most critical factor in your buying decision.
Oura: The Monthly Commitment
To get meaningful data from the Oura Ring 4, you must pay the $5.99/month membership. Without it, the ring is essentially useless, showing only three basic scores with no historical data.
- 2-Year Cost: $349 (Ring) + $143 (Sub) = $492
Samsung: Free Forever
Samsung disrupted the market by offering zero subscription fees. All your sleep data, Energy Scores, and health insights are free inside the Samsung Health app.
- 2-Year Cost: $399 (Ring) + $0 (Sub) = $399
Winner: Samsung Galaxy Ring. Over a 3-year ownership period, Samsung saves you nearly $200.
4. Battery Life & Charging: The Case for the Case
Samsung’s “Earbud-Style” Case
Samsung innovated brilliantly here. The Galaxy Ring comes with a transparent, portable charging case with its own battery (similar to Galaxy Buds or AirPods).
- Travel Friendly: You can charge the ring 1.5 times fully without plugging the case into a wall. This makes it the ultimate travel companion.
Oura’s Improved Puck
The Oura Ring 4 ships with a redesigned metal charging puck. It’s heavy, premium, and hard to tip over, but it must be plugged in to charge the ring.
- Longevity: While the Oura ring itself lasts slightly longer on a single charge (up to 8 days vs. Samsung’s 7), the lack of a portable charging case feels like an omission in 2026.
Winner: Samsung Galaxy Ring. The portable charging case is a game-changer for travel.
5. Compatibility: The “Walled Garden”
- Oura Ring 4: Works beautifully with both iOS (iPhone) and Android. If you switch phones, your ring moves with you.
- Samsung Galaxy Ring: Strictly Android only. While it can work with non-Samsung Android phones, you lose key features like “Energy Score” and “Find My Ring” unless you are paired with a Samsung Galaxy smartphone.
Verdict: If you have an iPhone, Oura is your only choice between the two.
Final Verdict: Which Ring Wins in 2026?
Buy the Oura Ring 4 if:
- You use an iPhone. (This is non-negotiable).
- You want the most accurate data. Oura’s algorithms are still a generation ahead in sleep staging and illness detection.
- You prioritize build quality. The full titanium interior feels significantly more premium than the epoxy alternatives.
Buy the Samsung Galaxy Ring if:
- You own a Samsung phone. The ecosystem integration (Watch + Ring) is flawless.
- You hate subscriptions. The $399 flat fee makes it cheaper than Oura after just 10 months of use.
- You travel often. The portable charging case is a feature every smart ring should have.
FAQ: Common Questions in 2026
Q: Is the Oura Ring 4 waterproof? Yes, the Oura Ring 4 is water-resistant up to 100 meters. You can safely wear it while swimming, showering, or snorkeling.
Q: Can I use the Samsung Galaxy Ring with an iPhone? No. As of 2026, Samsung has kept the Galaxy Ring locked to the Android ecosystem. iPhone users should opt for Oura.
Q: Does the Oura Ring 4 scratch easily? While the Oura Ring 4 is made of titanium, the PVD coating can develop a patina of micro-scratches over time. However, the Brushed Silver finish hides these much better than the glossy Gold or Black.
Q: Which ring is better for fitness tracking? Neither is a replacement for a GPS sports watch (like a Garmin). However, Oura’s automatic activity detection has improved significantly in 2025. For lifting weights, we recommend removing both rings to prevent scratching the ring and pinching your skin.
