The Oura Ring 4 launched in October 2024, replacing the Gen3 Heritage and Horizon as Oura’s flagship. The new generation adds 8-day battery life, a fully titanium build, redesigned sensors with 18 signal pathways, and broader sizing (4–15). Prices start at $349 for the Silver variant and go up to $499 for Gold and Stealth.

Why it’s #1: Ring 4 is the current flagship and the right buy for anyone starting fresh with Oura. The 8-day battery alone makes daily wear feasible without anxiety. Latest sensors capture data Gen3 can’t. At $349 silver, it’s priced identically to the older Horizon — no reason to buy older tech at the same price.

Check Price on Amazon →Oura Ring Sizing: Order the Free Sizing Kit First
Oura sells rings in 12 sizes (4–15) for Ring 4 and 8 sizes (6–13) for Gen3. Ring fit matters — too loose and the sensors lose contact; too tight and circulation suffers during sleep. Order the free Oura Sizing Kit before buying the ring.
The kit ships in 24–48 hours, includes plastic dummy rings in every size, and you wear them for 24 hours to find your true size. Most people wear ½ to 1 size larger on the index/middle finger than they do on the ring finger because of swelling and finger differences. Sizing kit is free directly from Oura’s website (search “oura ring sizing kit”).
Oura Membership: Is the $5.99/Month Worth It?
Both Ring 4 and Gen3 Horizon require an Oura Membership for full features. Without it, you get basic data; with it, you unlock:
- Sleep stages (Light, Deep, REM)
- Readiness Score and trends
- Cycle insights and pregnancy tracking
- Stress monitoring and resilience
- Personalized health reports
- Apple Health, Google Health Connect, Strava integrations
$5.99/month ($69.99/year prepaid) is the pricing as of 2026. New ring purchases include 1 free month. Without membership, the ring still tracks data but the app shows limited insights. Most users find the $5.99/mo worth it — it’s less than a single Starbucks order per month for research-grade biometric tracking.
Frequently Asked Questions
Is the Oura Ring 4 worth upgrading from Gen3?
If your Gen3 still works and battery hasn’t degraded, no rush. Upgrade if your Gen3 battery is below 4 days, you need wider sizing, or you want the latest sensors.
How long does the Oura Ring 4 battery last?
8 days on a single charge with default settings. Heavy workout tracking can reduce to 5–6 days.
What’s the difference between Oura Ring 4 Silver, Gold, and Brushed Silver?
Functionally identical. Different finishes only. Silver $349, Brushed Silver $399, Gold $499. Stealth and Rose Gold are also available at $499.
Does Oura Ring 4 work without a subscription?
Limited features only. Membership ($5.99/mo) unlocks sleep stages, Readiness Score, stress tracking, and most insights. New rings include 1 free month.
Can I wear the Oura Ring in the shower?
Yes. Both Ring 4 and Gen3 are water resistant to 100 meters. Safe for showers, swimming, and most water activities.
What size Oura Ring should I get?
Order the free Oura Sizing Kit first. It ships in 24–48 hours and includes dummy rings in all sizes to wear for 24 hours before you commit.
Is Oura Ring 4 better than Apple Watch for sleep tracking?
Yes for sleep — Oura’s ring form factor doesn’t interrupt sleep like a watch and the temperature sensors are more accurate than Apple Watch’s wrist measurement. Apple Watch wins for workout/activity tracking and notifications.
Does the Oura Ring 4 track HRV?
Yes. Heart rate variability is tracked overnight as part of the Readiness Score, and the Ring 4’s 18 signal pathways measure HRV more accurately than Gen3.
Final Thoughts
For new buyers in 2026, the Oura Ring 4 Silver at $349 is the clear pick — same price as Gen3 Horizon Silver but with 8-day battery, latest sensors, and wider sizing. Choose Brushed Silver or Gold only if the finish matters to you.
If you can find Gen3 Horizon discounted to $250 or less (often during Black Friday/holiday sales), it’s a solid budget entry. At full retail, Ring 4 wins.
Pair your Oura with an Apple Watch for activity tracking, or check our CGM guide for metabolic health tracking that complements Oura’s sleep and HRV data.
