Oura Ring 5 debuts as thinnest smart ring, starts at $399

Oura Ring 5 is the rare tech gift that looks like jewelry first and a health tracker second. That is exactly why it lands so well as a stealth-wealth present: it gives sleep scores, recovery data and activity tracking without the bulk or obvious screen of a smartwatch.

The new ring is Oura’s thinnest yet, measuring 6.09 mm wide and 2.28 mm thick, which the company says makes it 40 percent smaller than Oura Ring 4. It was rebuilt around a redesigned sensing architecture with 12 signal pathways, low-profile sensor domes and scratch-resistant titanium, and Oura says the design improves accuracy across more finger types and skin tones. It is also waterproof to 100 meters, with an IP68 rating, so this is not a delicate desk accessory. It is meant to be worn every day.

For gifting, the price matters almost as much as the silhouette. Black and silver start at $399, while Stealth, Brushed Silver, Gold and Deep Rose are priced at $499. That puts the ring in a more serious luxury-tech tier than the original Oura Ring 4, which launched in October 2024 at $349 and promised up to eight days of battery life. Forbes pegged the new model as carrying up to a $100 increase over prior versions, and that feels right for a product that is leaning harder into polish, not just sensors.

The finishes are part of the pitch. Gold has been reimagined in a lighter, more modern shade, and Deep Rose is new, with a copper-rose tone that feels more like fine jewelry than fitness gear. Oura says the upgraded battery system now runs six to nine days, which is exactly the kind of practical upgrade that matters once the ring becomes part of someone’s daily routine.

The software side got a lift too. New features include Health Radar, Live Activity Tracking, GLP-1 Insights, enhanced privacy controls and a better way to locate lost devices. Health Radar begins rolling out in June 2026 to Oura members in the United States, UAE and India on Oura Ring Gen3 and newer. After more than 13 years of development, Oura says it is on pace to surpass five million paid members this quarter, and the launch arrives just after its confidential IPO filing in May 2026, which only adds to the sense that this is the brand’s most mature, most covetable wearables play yet.
