💍 The Oura ring has become the equivalent of a "smart ring." It's a pioneer in this wearable electronics segment. Oura 5 is one one the best smart rings ever! See more in articles.
black friday
Live-updated Black Friday 2026 smart ring deals for US shoppers: Oura Ring 5, Ultrahuman Ring PRO, RingConn Gen 3 and Circular Ring 2, with last year’s prices for comparison and accuracy results from my chest strap tests.
smart ring
Seven nights, eight smart rings and a chest strap as the referee. Five rings recorded my night heart rate reliably and earn a recommendation. Three think I'm running up the stairs in my sleep — I wouldn't buy those.
💍Oura Ring Gen 3 & 4 & 5
A ring, a strap and a watch, worn together for 637 nights. HRV and heart rate match almost perfectly. The morning scores? That is another story.
💍Oura Ring Gen 3 & 4 & 5
With the Ring 5, Oura started showing how much your blood pressure drops at night. I compared it with the Hilo BP monitor for four months: single nights don’t match – the long-term trend does.
💍Oura Ring Gen 3 & 4 & 5
I strapped an Oura Ring 5 and a chest strap to one ordinary day — sleep, six workouts, the lot — and pulled the raw data. Here's how a smart ring actually measures your heart rate, and exactly where it goes quiet.
steps accuracy
Three of the newest smart rings, a scientific ankle pedometer on my leg and 20 days of real-life walking. Which one gets closest to reality? And why do all three (SPOILER!) count fewer steps than you actually take?
💍Oura Ring Gen 3 & 4 & 5
The Oura Ring 5 is radically smaller and slimmer than the Gen 4. But does the miniaturization cost you anything in the data? I wore both generations on the same night to find out.
💍Oura Ring Gen 3 & 4 & 5
Detailed comparison of size, weight, and battery of Oura Ring 5. See how the radical miniaturization turned out — and whether the upgrade is worth it.
💍Oura Ring Gen 3 & 4 & 5
Oura just surprised the market, dropping the Oura Ring 5 just 20 months after Gen 4. The latest iteration boasts a 40% smaller form factor, sharper tracking, and fresh app features—though thankfully, you won't miss out on the software upgrades even if you stick with an older model.
sauna
Is wearing wearables in a sauna like bringing sand to the beach? Not quite. Sand won’t exceed its operating limits. I took the Garmin Fenix 8, Whoop MG, and Oura Ring 4 into three ~100 °C sauna sessions. What did they measure—and does wearing them in a sauna make any sense?
sick
I hate being sick — so I’m testing whether smart rings can detect an approaching viral infection earlier than my own symptoms. I looked at Oura’s Symptom Radar, compared the data, and used SciSpace to separate science-based interventions from “I heard it from someone.” Which habits actually work?
🏆 Best smart ring
AI is becoming a big part of our lives and has now reached smart rings too. In this article, I compare 9 devices – from Whoop and Oura to Amazfit Helio – and their AI features like chatbots, personalized tips, or blood test analysis. Is there potential?
