💍Oura Ring Gen 3 & 4
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
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.
RingConn Gen 3
After testing every generation, I’m diving into the brand new RingConn Gen 3. With groundbreaking vascular trends, a built-in haptic motor, and a sleek new matte finish, this dark horse of the smart ring market continues to deliver premium hardware with zero subscription fees.
Six wearables, six different ages. From Garmin's Fitness Age to Oura's Cardiovascular metrics, we break down the algorithms, proxy data, and clinical accuracy of the world's leading smart devices. Stop guessing and start understanding your physiological trends.
elonga
No GPS. No screen. No steps tracking. No notifications. And still — after two years of testing every smart ring and screenless band I can get my hands on — it's one of the most interesting wearable I've come across. Let me explain.
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?
Ultrahuman PRO
On February 27, 2026, Ultrahuman unveiled the Ultrahuman Ring PRO – the third generation of its smart ring. It promises up to 15 days of battery life, new hardware, and a PRO Charging Case included in the box. What do we know, what don’t we know yet, and is upgrading from the Air worth it?
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?
elonga
In this article, I compare optical heart rate measurement in screenless bands from Elonga, WHOOP, Polar, and Amazfit against a chest strap with ECG-level accuracy. Same exertion, same methodology, same conditions. Or are they? And is it even possible to simulate the same conditions?
All the smart rings in one place and in context. Tests, reviews, answers, discounts, etc.
Ultrahuman is trying to connect bedroom environment data (like CO₂, noise, and light levels) with biometrics from the Air smart ring. The new Ambient Sleep Score aims to highlight how your sleep might be affected by your surroundings — though its interpretation still has some rough edges.
Let’s be honest. Most “Christmas deals” are recycled Black Friday leftovers. But you still get some nice deals.
Great battery life, unique sleep-apnea detection, compact design — that’s the RingConn Gen 2. And now the app has landed a very welcome update in version 3.13. VO₂ Max tracking, a new “Health Trends” view… and one big question: can the optical sensors really help track your circadian rhythm?
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?
If you’ve ever been tempted to buy a smart ring, now’s the perfect time. I haven’t seen smart rings go on sale like this before. Seriously.
Ultrahuman has confirmed a new generation of its smart ring called the Ultrahuman Ring Pro. The trademark is already registered. It may bring NFC payments, new sensors, and a redesigned look.
I arrived at the interview wearing my wearables – Garmin, Whoop, Oura, and the AI pendant Limitless. All detected stress, each differently. The highest peak? Garmin: 99/100 right in the middle of the talk. Which one told the truth? And what does the LLM say?
Omni Ring enters the smart ring market with a focus on AI and nutritional guidance. It promises a unique Energy QI metric similar to Garmin’s Body Battery, a charging case, and one month of premium subscription. But how does it compare to the holy trinity — Oura, Ultrahuman, and RingConn? Let’s see!
![Whoop 5 / MG – is it worth the money? [Review]](https://storage.ghost.io/c/01/ca/01ca9f1d-13b0-43d5-a8fe-dac2f7d3dc2f/content/images/size/w600/2025/10/WHOOP-MG-review.png)
A slightly different take on a review of the screenless fitness tracker Whoop. What drew me to it, and what put me off? What turned out to be true, and what’s just empty marketing wrapped in Cristiano Ronaldo? Heads-up: this is going to be a long review — but I believe it's worth your time.
Circular is back with the Ring 2 – a sleek smart ring packed with features and no subscription. But without the signature vibration motor and with reused hardware, can they really win back trust after a rocky start? Watch the unboxing and early thoughts.
Nova Ring R is a surprisingly solid budget smart ring. It tracks basic metrics — with decent hardware and minimalist design. A great entry point for anyone curious about smart rings without breaking the bank.
Who wouldn’t want smart boxers that wash themselves when needed, cool you down in summer, and keep you warm in winter? Well, that’s not what we’re talking about today. Whoops.
