Whoop, Elonga & Garmin: Wearable Reviews and Tests

Sleep

Orthosomnia — the wearable sickness. Do you have it?

For seven years I opened Oura every morning like a report card. Then I learned what I was doing had a name — orthosomnia. What it is, why trackers mislead us, and how I changed my approach.

💓 Elonga Review: 2+ Years with the Wearable That Only Asks for 3 Minutes of Your Morning

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.

Elonga vs Amazfit vs Polar vs Whoop: Which Is the Most Accurate?

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?

Whoop

Whoop 5 / MG – is it worth the money? [Review]

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.

Smart boxers: what do they measure, how do they work, and what are they for? Test!

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.

⏰ Garmin finally wakes you up smartly! Does it work?

Garmin Fenix 8 finally brings smart wake-up! I compare the new Smart Wake feature with the Oura ring, EEG, and older Garmin models. Does it really help reduce sleep inertia? I also revisit a 2018 email where I dreamed of this very feature.

Whoop 5.0 / MG – The Good, the Bad, and the Ugly (First Impressions)

Whoop 5.0 is here—smaller (?), more powerful (?), and up to 14 days of battery life. This article offers a fair and honest breakdown of what works, what the company got wrong, and where the new model still overpromises and underdelivers. Step tracking, comparison with the Whoop 4.0 included.

Whoop 5.0 Disappointment: No Free Upgrade and Controversial New Membership Model

Whoop 5.0 Is Here – Smaller, More Powerful, and With Up to 14 Days of Battery Life. But the New Membership Model Divides the Community. What does the MG model with an ECG sensor bring to the table? And why are some users disappointed by the broken promise of a “free upgrade”?
