The smarter ring that keeps your health in check.
Best for athletes and quantified-self users who want deep health metrics.
You forget the Ring 2 is on your finger by day three. That’s the headline. The first Galaxy Ring already beat the Oura Gen 3 on comfort, and Samsung sanded down the last rough edges — the inner band is smoother, the titanium feels lighter, and the lab member who wore it through a kayak trip didn’t notice it once. The new sizing kit also produces a fit you can actually rely on after the 24-hour test.
Two reviewers wore the Ring 2 alongside an Oura Ring 4 and an Apple Watch Ultra 2 for 21 days. We logged sleep stages against a Withings ScanWatch as a tiebreaker, ran heart-rate accuracy tests on a treadmill at 130/150/170 bpm, and tracked battery drain through full week-long stretches. We also tested the new energy score and stress trends against the equivalent Oura metrics across 14 overlapping days.
Without a display, glanceable info still requires a phone — the Ring is fundamentally a sensor, not a watch replacement. Workout auto-detection is hit or miss; cycling and yoga both flew under the radar more than once during our test. Galaxy phones get the full Samsung Health experience; iPhone support is read-only and feels like an afterthought. And resizing — even with the kit — is irreversible if you order wrong.
At $399 and no subscription, the Ring 2 is the better long-term value than Oura for Galaxy users — sleep tracking is genuinely accurate and battery life is real. iPhone users should wait or stick with Oura; the half-supported app makes the hardware feel hobbled in a way no firmware update will fully fix.
