Oura Ring 5 Official Release Date Confirmed
Oura officially announced the Ring 5 on May 28, 2026, far ahead of the late 2027 timeline that several outlets had been reporting. Pre-orders opened the same day. General availability and shipping kicked off on June 4, 2026 worldwide through Oura’s official store.
You can also buy it at US retail partners including Amazon, Best Buy, Costco, Target, and Walmart. International availability through select retailers started at the same time. Lab Uploads, a feature that lets you import medical test results, is confirmed to roll out globally on June 30, 2026.
Oura Ring 5 Price and Available Finishes
The Oura Ring 5 starts at $399 for the Silver and Black finishes. Premium finishes including Gold, Stealth, Brushed Silver, and the new Deep Rose colorway are priced at $499. That is a $50 increase over the Ring 4’s starting price of $349, which launched in October 2024.
The $99 Charging Case is sold separately and does not come in the box. On top of the hardware cost, the Oura Membership is still required at $5.99 per month or $69.99 annually. Without it, you only see three basic daily scores. There is no meaningful way to use this ring subscription-free.
Oura Ring 5 Specs and Features Breakdown
The Ring 5 measures 6.09mm wide and 2.28mm thick. The Ring 4 was 7.99mm wide and 2.88mm thick. That difference sounds small on paper, but on your finger it feels substantial. Twelve new signal pathways power the upgraded sensor system for better accuracy across more skin tones and finger types.
The ring is built from lightweight, non-allergenic titanium and is waterproof to 100 meters. New features include Health Radar with Blood Pressure Signals, Nighttime Breathing analysis with a 30-day rolling view, Live Activity Tracking, GLP-1 Insights for medication users, and a Locate feature to find a misplaced ring or case.

The Sizing Revolution No Sensor Bumps
Does the Oura Ring 5 have sensor bumps? No. The interior is completely flush and smooth. The internal components are 40% smaller, allowing the tracking sensors to sit flat against your skin. This is the most requested ergonomic fix from Ring 4 owners and Oura finally delivered it.
Previous Oura rings had raised sensor nodes on the inside surface. Over hours and days of wear, those small bumps caused irritation for people with smaller fingers or skin sensitivity. The Ring 5’s flush interior makes it feel like wearing a regular piece of jewellery. Comfort was clearly the top design priority this generation.
How a 40% Component Shrinkage Restructured Smart Jewelry
Oura rebuilt every internal layer from scratch to achieve this size reduction. The mechanical, electrical, optical, battery, and sensing architectures were each redesigned rather than just scaled down. Precision-engineered sensor domes replaced the older raised nodes while maintaining continuous skin contact. This is genuine micro-engineering work, not a cosmetic update.
According to Gizmodo’s hands-on review, the redesigned LEDs are more powerful than before, and the signal pathways are more precise. This directly improves heart rate accuracy at night and during workouts, which were two well-known weak points of the Ring 4 under real-world conditions.
Because the interior geometry changed so significantly, Oura is asking all buyers, including existing Ring 4 users, to order a new Ring 5 Sizing Kit before purchasing. At 40% smaller, the same size number will fit differently. This is not a marketing gimmick. Skipping the sizing step is the number one reason for smart ring returns across every brand.
New Diagnostic Frontiers Hypertension and Sleep Apnea
The Oura Ring 5 introduces Health Radar, a new software layer that replaces the older Symptom Radar tool from 2024. It includes two major health additions: Blood Pressure Signals and Nighttime Breathing. Both represent meaningful steps forward for a wearable ring, but both come with honest limits you should understand before buying.
Blood Pressure Signals do not work like an arm cuff. The ring uses sensors to track changes in blood flow and blood vessel behaviour that correlate with high blood pressure patterns. Think of it as a cardiovascular trend spotter over time, not a real-time measurement of your systolic and diastolic numbers on any given morning.
Tracking Vascular Trends Without an Inflatable Cuff
As Tech Advisor’s editorial team reports, Blood Pressure Signals launched in the US, India, and UAE in June 2026. Other regions will receive the feature as local health regulatory approvals are granted. This staggered rollout is standard practice for clinical-adjacent health features, not a product shortcoming.
Nighttime Breathing gives users a 30-day rolling view of sleep-related breathing disturbances. The ring’s LED sensors monitor significant shifts in blood oxygen levels during sleep. Large or repeated drops may indicate a pattern worth discussing with a doctor. However, the Ring 5 is not cleared by the FDA to diagnose sleep apnea and Oura does not claim it is.
If you or someone you live with already suspects sleep apnea, treat any wearable data as a conversation starter with a medical professional, not a final answer. This feature’s real value is spotting patterns over weeks that you might never notice on your own.

Battery Innovations and Charging Compatibility
The Oura Ring 5 battery delivers six to nine days of use per charge. Oura reduced the physical battery size as part of the overall 40% size reduction, yet maintained a similar runtime to the Ring 4’s eight-day maximum. Larger ring sizes naturally have more internal volume, which translates to longer battery life in practice.
The optional Charging Case costs $99 and is not included in the box. It stores enough charge to refill the ring four full times before the case itself needs to be plugged in. According to MacRumors’ launch coverage, the case also supports wireless charging, which the standard ring charger does not. It doubles as a travel companion for people who want extended time away from wall outlets.
The case also includes the new Locate feature, which lets you ping the ring or the case itself from the Oura app if either goes missing. This is a small but practical addition that smartly addresses a real-world scenario: small rings are easy to misplace.

Buy If:
- You have sensitive skin or small fingers that the Ring 4’s sensor bumps irritated or you are new to smart rings and want the best hardware available right now
- You want blood pressure trend data or a 30-day breathing pattern view and you are based in the US, India, or UAE where those features are live from launch
Skip If:
- You already own a Ring 4, are comfortable with it, and your primary goal is blood pressure data since that feature may roll out to older hardware via software updates
- You are on a tight budget and cannot absorb the $399 hardware cost plus $5.99 per month subscription on top of an optional $99 case
Wait If:
- You are outside the US, India, and UAE and blood pressure or breathing features are your main motivation since regional approvals are still in progress
- You are eyeing discounted Ring 4 closeout deals right now; stop and wait for Ring 5 if comfort is your concern because the ergonomic gap between the two is real and daily
