The Oura Ring 5 is available for pre-order now, with shipping set to start June 4. Oura says the new smart ring is 40% smaller than the Ring 4, while also adding longer battery life and new health tracking features.
That is a sharp turn for a category that usually moves in tiny increments. The smart ring market has become more crowded, especially with subscription-free rivals pushing harder, so Oura’s answer is partly design and partly software: a lighter ring, a beefed-up health monitoring system, and a faster release cadence than many expected.
Oura Ring 5 size, materials and battery life
The Ring 5 measures 6.09mm wide and 2.28mm thick, with the smallest sizes starting at 2 grams. Oura says it rebuilt the mechanical, electrical, optical, battery, and sensing systems to get there, which is corporate shorthand for ”we changed almost everything and hope the user only notices the ring got slimmer.”
- Width: 6.09mm
- Thickness: 2.28mm
- Smallest sizes: 2 grams
- Battery life: six to nine days
- Ring 4 battery life: five to eight days
Battery life gets a modest bump, from five to eight days on the Ring 4 to six to nine days here. That is not headline-grabbing on its own, but for a device meant to be worn constantly, shaving off bulk without sacrificing endurance is the sort of win that actually matters.
Health Radar adds background monitoring
The bigger software addition is Health Radar, a background monitoring feature that watches biometrics and flags patterns worth a closer look. It launches with two tools: Blood Pressure Signals, which tracks cardiovascular patterns during sleep, and Nighttime Breathing, which gives users a 30-day rolling view of sleep-related breathing disturbances.
Both of those launch only in the US, India, and the UAE. That limited rollout is familiar territory for health wearables, which often start with a narrower regulatory footprint before expanding, but it still leaves a lot of buyers waiting while the marketing does its victory lap.
Live activity tracking comes to older Oura rings too
Oura is also adding live activity tracking on June 4, letting users follow pace, distance, and heart rate during workouts inside the app. Unlike the new health features, this one rolls out globally and works with Oura Ring Gen 3 and later, not just the new model.
That broader support is a smart move. It gives existing customers a reason to stay in Oura’s ecosystem while the company asks new buyers to pay up for the latest hardware.
Oura Ring 5 price and membership
Pricing starts at $399 for Silver and Black. Gold, Stealth, Brushed Silver, and Deep Rose cost $499. The charging case is $99, sold separately, and Oura membership still applies at $5.99 per month or $69.99 per year.
- Silver and Black: $399
- Gold, Stealth, Brushed Silver and Deep Rose: $499
- Charging case: $99
- Membership: $5.99 per month or $69.99 per year
The odd twist is timing. The Ring 4 launched only a year and a half ago, so this refresh arrives faster than Oura’s usual pace. With RingConn and other rivals leaning on the ”no subscription” pitch, Oura appears to be betting that smaller hardware and stronger health features are enough to keep people paying. The real question now is whether buyers care more about the ring on their finger – or the bill attached to it.
