All that remained was the quiet, stunned helplessness of a man who had fallen in love with something he could not have — just the hollow echo of a desire that had nowhere to go.CogitActive
That is where the previous chapter left me. My quest for sleep-tracking precision had reached a dead end; my list was empty. The Oura Ring 4 — the only truly viable choice — had been ruled out by its subscription model, a line I would not cross. The two alternatives that had briefly flickered like escape routes — the RingConn Gen 2 and the Ultrahuman Ring Air — had both collapsed under The Quantified Scientist’s scrutiny, exposed as some of the worst performers. Exhausted, hollowed out by a weekend that had stolen my sleep and replaced it with obsession, I could feel my mind sliding into a peculiar kind of desperation.
It is a frightening thing to witness the speed of one’s own collapse. Twenty-four hours. That was all it took for the ground to shift beneath my feet—for certainty to crumble into longing, for indifference to curdle into desperation. In the span of a single day—a period now stretched across four chapters 2—I had gone from total apathy to absolute fixation.
I had begun the weekend not caring whether I wore a bracelet, a step-counter, or nothing at all. And now I cared about nothing else. I was consumed by a single, relentless craving: the one object I had sworn was forbidden. The Oura Ring 4. The untouchable prize. The impossible desire. My research for alternatives had failed—leaving me with nothing but the gnawing certainty that the one thing I wanted was the one thing I could not have. Hope had evaporated.
The Oura Ring 4 was no longer just hardware—it had become a taunt. A quiet, mocking glint on every scatter plot I reopened, it sat at the center of my attention, the sole object of my fixation. Nothing else mattered. Not reason. Not principle. Not the carefully constructed boundaries I had once believed in. Want had taken the wheel, and reason had been relegated to the backseat, a feeble voice shouting into the void.
“How much of myself was I willing to sacrifice?”
So, I did what any unraveling man would do: I began the arithmetic of self-denial. What could I cut? Nothing. I had nothing left to sacrifice. A decade of discipline had left me with little to spare. My last personal purchase—a phone, nine years ago. Not a choice, really. The world simply refused to function without a smartphone anymore. My old BlackBerry no longer counted; banks, apps, all of it demanded a new (European-compatible) device. Clothes? I had not even bought any since leaving the United States, 11 years ago! My wardrobe was a relic of a past life. Fortunately, my clothes are Texas Tough—still in good shape after 11 years. So, even if I were allowed one act of weakness, there was no room for one foolish indulgence.
What else could I cut? The question spiraled. I ran through the inventory of my life like a man cataloging his organs for sale. My website? I had already trimmed the hosting for my upcoming podcast just to keep the ledger from bleeding. Was I prepared to sacrifice CogitActive itself? The cost was more than I liked to admit—my hosting provider and registrar had both raised their prices to absurd levels in recent years. I’d documented their greed in posts like Is the hike in SiteGround prices justified? and Gandi.net’s outrageous price hike, but I’d never found the time to migrate. Time, the scarce resource, as always! And even if I would find the time to seek good alternatives, would the price cut be enough to cover the ring’s monthly toll? Or should I burn it all down, sell the domain, close the servers… Would that be enough?
Desperate, I opened the family budget again, looking for the sacrifice someone else might bear. Maybe I could find the hidden fissure where I could lever something loose. The humiliating, self-betraying math of a man trying to carve money from a life already pared to the bone. But that was already the line, already the discipline, already the quiet austerity of our life. There was no hidden abundance. No secret stash of unnecessary pleasures quietly accumulating 3. Food? Already limited to items on sale. Leisure? None. No time for that anyway. Vacations? Just once a year, and it was for my son to see his grandparents in France.
My pen hovered there. I stared at that line for a long moment. Our once-a-year trip for my son to see his grandparents? A line I could remove. A vacation I could rationalize away if I just told myself the right story—that one year without the France trip wouldn’t matter, that his grandparents would understand, that sleep tracking was health and health was sacred too, and my health mattered, didn’t it? No! I could not justify cutting that, not even for the promise of better health.
I was ready to cut something that wasn’t mine to cut. Something that belonged to my son’s relationship with his grandparents. Something that no obsession, no promise, no object on my finger was worth sacrificing. And here I was, mad enough, desperate enough, sleep-deprived enough to consider it. That was the moment I understood the depth of my madness. Not the obsession itself. The willingness to transgress against what mattered most. Reason returned, if only as revulsion.
So I renounced the ring.
I gave up the ring. Not in peace. In necessity. The renunciation was not dignified. There was no ceremony, no noble acceptance. I sat there, in front of the budget I had opened in desperation, and I felt the collapse of everything I had been chasing. I closed my laptop. The search was finished. There was nothing left to find, nothing left to want. I had surrendered—and in that surrender, I felt the strange hollow relief of a man who has finally stopped fighting. I told my wife this was over and went to take a bath. I needed to wash away the weekend.
When I emerged, she called me:
“Can you come, please? What about this one? Did you check it?”
Not the Ultrahuman Ring AIR—the one I had already dismissed, the one The Quantified Scientist had condemned to the lower end of the scatter plot. This was a new model. This was something I didn’t even know existed 4.
PRO
Performance by Design
I stared at it. At the sensors themselves: a red and a green square LED embedded in dark, transparent grey material, like circuitry pulled from Darth Vader’s chest. There was something at once menacing and vulnerable about it—this tiny creature of electronics that was supposed to know me better than I knew myself. I was still looking at those colored squares when she opened a second tab. Specifications. And there, buried in the technical prose, she pointed me to a single raw:
Heart-Rate Sensor Redesigned PPG with improved signal quality during sleep and recovery.
At the time, I didn’t know anything about PPG (aka photoplethysmography). I didn’t know how wearables rely on it to “guess” your sleep. All I saw was the word “sleep.” All I focused on was a comparison table between the PRO and the AIR and a standout difference: a redesigned PPG. Could the former PPG explain why the ring AIR had been so bad at tracking sleep?
There was no claim of improved sleep tracking, but it didn’t matter. At that moment, I seized that very line—improved signal quality during sleep
—like a man drowning. Not cautiously. Not rationally. I clamped onto that sentence as if my sanity depended on it. As if a redesigned sensor, a specification I barely understood in this context, could rebuild everything I had just surrendered. And in that moment, at the absolute bottom, it did.
The redesigned PPG sensor was nothing more than a specification. A promise. A line of text floating in the void. But I didn’t need evidence yet. The ring only needed to exist as a possibility, and that was enough to do something I hadn’t thought possible a few hours earlier: it cured me, cleanly and completely, of the Oura Ring 4. The forbidden ring, the one that had pulled at me for a full spiraling weekend, simply loosened its grip the moment a new dream took its place. Of course, I swapped one obsession directly for another. But at that moment, in that darkness, the swap felt like salvation. A new ring had entered the story. And with it, something else returned. Hope.
I spent the rest of that weekend—and, predictably, another sleepless night—scouring for every scrap of information I could find about the Ultrahuman Ring PRO. But the ring wasn’t due until May 15th, and until then there was almost nothing to hold onto. No reviews. No teardowns. Nothing on sleep. No rigorous validation against EEG-based gold standards. The Quantified Scientist, the voice I had learned to trust above all others, had not yet tested the ring.
The sole substantive reference was an unboxing by Chase the Summit (external link). He couldn’t test the ring yet—it simply hadn’t been released. In fact, he focused almost entirely on the new charger 5. His commentary was detailed and deliberate, presented with the authority of someone who understood engineering. In my state—grasping, desperate, needing something to believe in—I made a simple inference: if Ultrahuman had engineered this much precision into an accessory, into something that wasn’t even the point, maybe they had applied the same rigor to the ring itself.
I know how this sounds. I know that I was grasping at a charger like a man grasping at driftwood. I know that a redesigned sensor was not evidence. I know that the hope was disproportionate to how little I actually knew. But something had shifted; I had found a new object. A new reason to believe that precision was still possible. The absence of evidence became evidence of possibility. Because the ring had not yet failed, it remained perfect. The unknown became a kind of shelter — a small, dark room in which hope could survive undisturbed. A fragile, suspended peace, until the release date in 19 days—May 15—or, more importantly, the dreaded sleep validation.
Now I just had to wait (and hope).
To be continued…
1 TL;DR: After initially dismissing the idea of a step counter, I shifted focus to sleep tracking — an old personal quest that had stalled years ago due to unreliable tech. Flash forward to 2026: things haven’t changed (most wearables overpromise and underdeliver, especially when it comes to EEG-grade accuracy); yet not all are equally bad. Enter The Quantified Scientist, a YouTuber who tests wearables against gold-standard EEG devices, and the shiny exception: the Oura Ring 4. Its mandatory subscription, however, disqualified it. In a short period of time, I was left with nothing but a mind unraveling under the weight of obsession — for the only viable option I could not accept. ^
2 Yes, four—not five. The first chapter, which predates my late April descent into madness, serves as a quiet prologue to the storm that followed. ^
3 We are not people under a bridge. We save with a discipline that borders on ritual—a philosophy of restraint born from the belief that some things matter more than comfort. We make these sacrifices for our son’s education, and there is no negotiating with a child’s future, no matter how loudly a ring insists it might save my sleep. ^
4 How she found what I could not remains partly a mystery to me. Geolocation, I suspect, had trapped me in a false present—Google’s algorithms convinced me I was living in 2024, not 2026, which meant the new devices hadn’t yet arrived in “my” timeline (remember how the same geolocation fog kept RingConn Gen 2 hidden from me back in Chapter 5). My wife navigates Czech websites with native fluency. I search in English. Whether that linguistic difference cracked the veil of the Czech-lag (the peculiar temporal distortion created by regional availability delays and algorithmic assumptions), I honestly cannot say. ^
5 For context, the Ultrahuman Ring PRO’s charger represented a significant departure from previous models. Earlier docking stations were size-specific, requiring different physical docks for different ring sizes. The PRO Charger introduced a universal design, using a central magnetic pin post that accommodates any ring size seamlessly. Rather than relying on inductive charging (which generates excess heat), the PRO uses physical contact points, significantly reducing thermal output and preserving long-term battery health. The charger case itself is a self-contained power bank: it holds up to 45 days of charge, enabling portable use without an outlet. Additionally, the case contains onboard storage capable of backing up a full year of ring data when the user is entirely offline—valuable for maintaining health records during travel or internet outages. As a final technical flourish, the case houses an embedded speaker system and haptic engine, allowing users to locate a misplaced charger via the Ultrahuman app through proximity guidance and audible beeping. ^
