Is the Oura Ring 5 worth upgrading to if you already own a Ring 4?

The Oura Ring 5 is about 40 percent smaller than the Ring 4 and lasts 6 to 9 days per charge, starting at $399 plus a required $5.99/month membership. But its headline Health Radar software also reaches the Ring 4 and most of Gen 3, so the upgrade is mainly comfort and battery.

Your smart ring already tracks your sleep fine, then a smaller, shinier one launches and your wallet starts itching. Short answer: For most Ring 4 owners, no — not yet. The Ring 5 is about 40 percent smaller (6.09mm wide, 2.28mm thick, from about 2 grams), lasts 6 to 9 days per charge versus the Ring 4’s 5 to 8, and starts at $399 for Silver and Black or $499 for premium finishes, plus a required membership at $5.99 a month for full insights.

Gadgets 360 reported its India launch on October 22, 2026, with AI health features and blood-pressure tracking. Why it matters: The headline new software, Health Radar — including Blood Pressure Signals, which tracks overnight blood pressure patterns and lets you log cuff readings — also reaches the Ring 4, and most of it reaches Gen 3 too. So the real upgrade is comfort and a slightly longer battery, not exclusive features.

And the true price is never just the ring: it is the hardware plus membership, every year you wear it.Decide in this order:1. Check your app first. Open the Oura app and see whether Health Radar and Blood Pressure Signals already appeared on your current ring.2.

Add up the true year-one cost. Ring price plus about $72 in membership — $471 or more before you have worn it a day.3. Upgrade only for comfort, battery, or a first ring.

If your current ring is uncomfortable overnight, its battery no longer lasts the week, or this is your first smart ring, the upgrade makes sense.4. Get sized before you order. Ring 5 sizes run 6 to 13, narrower than the Ring 4’s range of 4 to 15 — your old size may not exist.Common mistake: Judging a smart ring by the sticker price alone.

The membership is required for the full sleep, readiness, and health insights, so a cheaper ring with a subscription can cost more over two years than it looks.Ad’s take: Smaller and lighter is a real win for something you sleep in, I’ll give it that. But if the new tricks already showed up free on the ring on your finger, keep your $399 and sleep just as well.
