OURA JUST ANNOUNCED the launch of its biggest (but in a literal sense, smallest) innovation to date: the Oura Ring 5<\/a>. The brand promises the latest in its expansive line of high-powered smart rings<\/a> will be its most compact version yet, and 40 percent smaller than the Oura Ring 4<\/a>. Pre-orders are now open on its site with first shipments going out on June 4.<\/p>\n We\u2019ve tested every Oura Ring since the first release, and one of the critical steps we recommend before purchasing a ring is getting one of Oura\u2019s sizing kits<\/a>. This kit is only $10, and the amount is applied toward the cost of the ring, but it assures that you get right the best fit for your finger. Each new iteration of the Oura Ring is a bit different, and the best readings come when it is snug on your forefinger.<\/p>\n OURA RING 5 SIZING KIT<\/a><\/p>\n Our editors have worn the Oura Ring 4<\/a> since it was released in late 2024 and have been impressed by its comfort, which easily fits into any active individual\u2019s lifestyle. So the idea of an even more low-profile offering has us excited.<\/p>\n In addition to the 5\u2019s new lightweight design, Oura also says it\u2019s the most accurate version to date. The latest model introduces proprietary software features that combine your historical clinical metrics with real-time biometric insights for a more predictive view of your overall health. The 5 will introduce an expansion to its Symptom Radar\u2014one of our favorite components of the 4, which was our best-tested smart ring<\/a> of 2025.<\/p>\n An overhaul of the ring\u2019s electrical, mechanical, battery, optical, and sensing designs makes for a ring that\u2019s both lighter and thinner than previous iterations. It also introduces a smoother curvature for a more natural, all-day fit. The Oura Ring 4 was noticeably more comfortable in our testing than its predecessor, ditching nodules on the inside of the ring and shifting to a full titanium build.<\/p>\n The 5 is made with a similar lightweight non-allergenic titanium that Oura touts as \u201cmore durable and scratch resistant\u201d than the 4. It\u2019s also now fully waterproof; the 4 was water-resistant up to 100 meters.<\/p>\n Members can now also upload lab results directly into the Oura app for a more comprehensive view of their overall health. A new opt-in, IRB-approved study in Oura Labs pairs cognitive assessments from Cambridge Cognition to monitor your cognitive health. The ring also features Blood Pressure alerts to detect spikes, and it can now track patterns during sleep, when they are clearest. Similarly, the 5 implements a 30-day rolling view of sleep-related breathing patterns and disturbances to monitor if and how breathing changes are impacting your sleep.<\/p>\n We\u2019ve started testing the new ring, and will be reporting back after we\u2019ve spent some time with the new device. But all things considered, it looks like the latest version of one of our all-time favorite fitness trackers<\/a> will be Oura\u2019s best yet. And you won\u2019t have to wait long to get your hands on one either.<\/p>\n![\"Ring](\"https:\/\/www.newsbeep.com\/ca\/wp-content\/uploads\/2026\/05\/206d406a-3aa1-43aa-b631-3f198493e0ab.jpg\" "\\"Ring")
