Samsung Galaxy Ring vs Oura Ring Gen 3 — 2025 Comparison Review

Smart rings are the hottest wearable trend of 2025, offering discreet health tracking without the bulk of a smartwatch. Two leaders dominate the conversation: Samsung’s Galaxy Ring and the Oura Ring Gen 3. Both promise advanced biometrics, sleek design, and lifestyle integration, but they take very different approaches to pricing, ecosystem, and features.

The Samsung Galaxy Ring is the newcomer, launched in 2024 to extend Samsung’s health ecosystem. It tracks sleep, heart rate, stress, and activity, and integrates seamlessly with Galaxy phones and watches. Unlike Oura, Samsung includes all features in the purchase price — no subscription required. That makes it appealing for buyers who want a one-time investment and already use Samsung devices. The trade-off is ecosystem lock-in: Galaxy Ring works best with Samsung Health and Galaxy hardware, limiting cross-platform flexibility.

Oura Ring Gen 3, by contrast, is the established player. It offers deep sleep analysis, readiness scores, HRV, body temperature, and more than 20 biometrics. Its app is polished and integrates with Apple Health, Google Fit, Strava, and Natural Cycles. The catch is the Oura Membership: $5.99/month for full insights. That ongoing cost makes Oura less appealing for budget-conscious buyers, but its breadth of integrations and wellness focus remain unmatched.

This comparison breaks down features, pros and cons, and verdict so you can decide which smart ring fits your lifestyle. If you want subscription-free health tracking and already own Samsung devices, Galaxy Ring is the clear choice. If you want the deepest sleep insights and broad app integrations, Oura Ring Gen 3 remains the leader — provided you’re comfortable with the membership fee.
