Oura's fifth-generation smart ring is smaller, packs upgraded sensors, and somehow manages to last longer on a charge.
The Ring 5 ships with a slimmer titanium build and a new feature set called Health Radar, which Oura describes as proactive — meaning it surfaces insights rather than waiting for you to hunt through dashboards. Battery life improves despite the thinner chassis, a trade-off that usually runs the other direction. Oura hasn't put the device in independent hands yet, so those claims come from a controlled first look, not real-world testing.
The timing is pointed. Oura built the smart ring category essentially alone for years, then Samsung launched the Galaxy Ring and introduced actual competition. Health Radar reads as the strategic answer to that: reframe the device from passive logger to something that acts on your behalf, which also conveniently deepens the case for Oura's subscription model. If this market is going to consolidate around two serious players, feature differentiation is where that fight gets decided.
Whether Health Radar amounts to something genuinely useful or just a more assertive notification layer is a question a pre-release first look cannot answer.
