Same price. Same form factor. One charges you $72 a year to see your own data. The other doesn’t.

Ultrahuman opened US pre-orders for the Ring Pro on March 24, 2026. It ships May 15. The price: $349. That’s the exact same sticker as the Oura Ring 4 aluminum. The difference is what happens after you buy it. With Ultrahuman, nothing. No subscription, no premium tier, no trial period ticking down to a paywall. You pay once.

With Oura, you pay $349 for the ring, get six months of free app access, then start handing over $5.99 every month until you cancel or die. Whichever comes first.

I’ve been tracking the no-subscription wearable space closely this year, covering the $75 Pebble Index 01 and Garmin’s CIRQA band. But Ultrahuman hitting the US at $349 with zero recurring costs is a different kind of threat to Oura. This isn’t a budget alternative or a different form factor. It’s the same product category, same price point, minus the subscription. That’s never happened before.

Quick Comparison

Feature	Ultrahuman Ring Pro	Oura Ring 4
US Price	$349 one-time	$349 + $5.99/month
Subscription	None, ever	Required after 6-month trial
3-Year Total Cost	$349	~$707
Sleep Tracking	Yes (staging + latency)	Yes (best-in-class staging)
HRV	Continuous overnight	Continuous overnight + trends
Skin Temperature	Yes	Yes
SpO2	Yes	Yes
Readiness/Recovery Score	Yes (Movement Index)	Yes (Readiness Score)
Activity Tracking	Steps, calories, workout HR	Steps, calories, auto-detection
Battery Life	4-6 days	5-7 days
Water Resistance	10 ATM	10 ATM
App Quality	Clean, improving fast	Polished, deep trend data
Metabolic Tracking	PowerIndex, metabolism score	None
Unique Feature	Cyborg mode (real-time HR)	Skin temp illness detection

Quick answer: If you refuse to pay monthly for biometric data and want a premium smart ring with full sensor suite, the Ultrahuman Ring Pro is the most credible no-subscription Oura alternative at any price. If you already trust Oura’s recovery algorithm and the subscription doesn’t bother you, Oura’s software maturity still leads.

The 3-Year Cost That Nobody Can Ignore

I keep running this math because buyers keep underestimating it.

Timeframe	Ultrahuman Ring Pro	Oura Ring 4 (Aluminum)	You Save with Ultrahuman
Purchase Day	$349	$349	$0
Year 1	$349	$385 (6 months free, then $5.99/mo)	$36
Year 2	$349	$457	$108
Year 3	$349	$529	$180
Year 4	$349	$601	$252
Year 5	$349	$673	$324

Over three years, Oura costs you $180 more. Over five years, $324. Not enormous numbers on their own. But that $5.99/month is the floor, not the ceiling.

Here’s why that matters right now.

The Oura IPO Factor

Oura is in active IPO negotiations at a reported $11 billion valuation. I wrote about what that means for pricing two weeks ago. The short version: every fitness company that has gone public has raised subscription prices within 18 months. Peloton did it. Fitbit did it. The pattern is clear.

Oura’s $5.99/month becomes $7.99 or $9.99 post-IPO. That’s not cynicism — that’s what public market pressure does to subscription businesses. Analysts want to see average revenue per user climb every quarter. The easiest lever is price.

Run those same 3-year numbers at $7.99/month:

Oura Ring 4 at $7.99/mo (post-IPO estimate): ~$589 over 3 years. That’s $240 more than the Ultrahuman Ring Pro. For the same category of product.

Ultrahuman’s pitch has always been anti-subscription. They’ve operated that way in India and Europe for two years. Now they’re bringing it to the US market at the exact moment Oura’s financial incentives are about to push prices higher. The timing isn’t accidental.

What Is the Ultrahuman Ring Pro?

For anyone who hasn’t tracked Ultrahuman — and most US buyers haven’t, since US availability was limited until now — here’s the rundown.

The Ring Pro is Ultrahuman’s second-generation smart ring. Titanium body. Optical heart rate, SpO2, skin temperature, and accelerometer sensors. It tracks sleep stages, overnight HRV, blood oxygen, temperature deviations, and daily activity. The companion app (iOS and Android) gives you a Movement Index (their readiness score), sleep analysis, and what they call PowerIndex, a metabolic scoring system that combines activity, recovery, and sleep data.

The signature feature is “Cyborg mode,” which provides near-real-time heart rate monitoring from a ring. Most smart rings only sample HR periodically. Ultrahuman claims continuous readings during active tracking, though battery takes a hit when you use it.

They also sell an optional CGM (continuous glucose monitor) integration called Ultrahuman M1, which feeds blood sugar data into the same app alongside ring data. That’s a separate $299 sensor (not required), but it’s unique in the ring space. Nobody else connects ring biometrics with real-time glucose data.

Where Ultrahuman Ring Pro Wins

The obvious one: no subscription. Your $349 buys the hardware and all current and future software features. Ultrahuman has stated publicly (and repeatedly) that they will never charge a subscription. They make money on hardware and their CGM sensor. That’s a business model I can respect, even if margins are thinner.

Metabolic features. The PowerIndex and metabolism scoring are genuinely different from what Oura offers. They’re designed around the idea that recovery isn’t just about sleep and HRV — it’s about metabolic readiness. Whether that translates to better training decisions is something I’ll need weeks of wear time to evaluate, but the framework is more ambitious than Oura’s Readiness Score.

Cyborg mode for workouts. Real-time heart rate from a ring during training is useful if your ring is your only wearable. I wear a Garmin for workouts, so this matters less to me. But for people who don’t want a watch, getting live HR zones from a ring during a run or lifting session is legitimately handy.

App design is clean. Ultrahuman’s app won’t overwhelm you. The interface is minimal, scores are prominent, and the daily view is scannable in 30 seconds. Some people prefer Oura’s data density. I think Ultrahuman made the right call for a wider audience.

Where Oura Ring 4 Still Wins

Sleep tracking accuracy. After 14 months with Ring 4, I trust its sleep staging more than any other consumer wearable. The 2026 app redesign made the data more accessible, and Oura’s staging aligns with polysomnography studies better than competitors I’ve tested. Ultrahuman’s sleep tracking is good. Early adopter reviews show accurate total sleep time and decent staging. Oura has more published validation data behind its algorithms.

Readiness Score refinement. Oura’s multi-factor Readiness Score weighs HRV, resting heart rate, body temperature, sleep quality, recent activity, and previous recovery. It’s been refined over years with data from millions of users. When my Oura says 42, I change my workout. That trust took months to build. Ultrahuman’s Movement Index uses similar inputs but hasn’t had the same public scrutiny or validation period.

Temperature-based illness detection. This is the feature that’s saved me twice during training blocks. Oura’s temperature trend flagged a cold 18 hours before I had symptoms, which let me rest instead of pushing through a key workout and losing a week. Ultrahuman tracks skin temperature too, but Oura’s trend analysis and alerting system for temperature deviations is more mature.

Ecosystem and community. Oura has years of third-party integrations, research partnerships, and a larger user community. The app’s 7/30/90-day trend views are excellent for long-term pattern recognition. Ultrahuman is building this out but started later.

What About Pebble and Garmin CIRQA?

The no-subscription wearable market got crowded fast in 2026. Ultrahuman slots in alongside the other options we’ve reviewed:

Device	Price	Form Factor	Subscription	Best For
Pebble Index 01	$75	Ring	None	Budget sleep tracking
Garmin CIRQA	TBD (one-time)	Band	None	Garmin ecosystem recovery tracking
Ultrahuman Ring Pro	$349	Ring	None	Premium ring, no subscription
Oura Ring 4	$349 + sub	Ring	$5.99/mo	Best-in-class sleep + recovery
Samsung Galaxy Ring	$399	Ring	None	Samsung ecosystem

Ultrahuman occupies a specific niche: premium smart ring with full sensor suite, no subscription, at Oura’s exact price point. Pebble is the budget play. CIRQA is a band, not a ring. Samsung locks you into the Galaxy ecosystem. Ultrahuman is the first direct, same-price, same-form-factor competitor to Oura that doesn’t ask for monthly payments.

Who Should Pre-Order the Ultrahuman Ring Pro

Subscription-allergic ring buyers. If you’ve been eyeing Oura but the $72/year subscription kills it for you, this is literally the product you’ve been waiting for. Same price, same form factor, zero recurring cost. The subscription fatigue across fitness wearables is real, and Ultrahuman is the first ring-shaped answer at the premium tier.

People who want metabolic data. If you’re interested in the CGM integration or metabolic scoring alongside biometrics, Ultrahuman is the only ring doing this. Nobody else connects glucose data with ring-based recovery metrics.

International travelers or India-based readers. Ultrahuman has been shipping globally for two years. The Ring Pro isn’t new hardware globally; it’s new to the US market. That means more real-world data exists than you might think. Reviews on Reddit and Amazon India have been largely positive on hardware quality.

Who Should Stick with Oura

Serious athletes who trust their Readiness Score. If Oura’s recovery data already changes your training decisions daily, switching carries risk. Ultrahuman’s Movement Index might be just as good. It might not. You won’t know for months, and those months of uncertain data could cost you training quality.

People who value illness detection. I mentioned Oura’s temperature trend caught me twice before symptoms hit. That feature alone might justify the subscription. Ultrahuman tracks temperature but hasn’t demonstrated the same alerting reliability yet.

Anyone deep in Oura’s trend data. Twelve-plus months of Oura data and long-term seasonal patterns don’t transfer to a new platform. Starting over means losing that history. Data portability between ring platforms basically doesn’t exist.

The Bigger Picture

When I reviewed the Pebble Index 01 three days ago, I wrote that the $300+ floor for smart rings was artificial. Now Ultrahuman is proving something else: the subscription model on top of premium hardware pricing was a choice, not a necessity.

Oura charges $349 for hardware AND $72/year for software. Ultrahuman charges $349 for hardware and software. Both companies make titanium smart rings with optical sensors and employ engineers to build recovery algorithms. One decided to charge you forever. The other decided not to.

With Oura’s IPO looming and the Ring 5 already showing up in FCC filings, the next 12 months are going to be interesting. Oura will need to justify its subscription to an increasingly skeptical market while simultaneously satisfying public investors who want that subscription revenue to grow.

Ultrahuman just has to make a good ring and sell it. Simpler business, simpler pitch.

The Bottom Line

The Ultrahuman Ring Pro at $349 with no subscription is the most direct challenge to Oura’s business model that the smart ring market has produced. Same price, full sensor suite, zero monthly fees. Over three years, you save $180 minimum, likely more after Oura’s inevitable post-IPO price hike.

Is Oura still the better product? Probably. The sleep tracking is more validated, the recovery algorithm has more refinement, and the ecosystem is deeper. But “better” has to be weighed against “how much more will it cost me over the life of the product.” And that gap is widening.

My take: if you don’t currently own a smart ring and the subscription model bothers you, pre-order the Ultrahuman Ring Pro. You get 90% of Oura’s functionality for a fixed cost. Already wearing an Oura and trusting the data? Stay put. But keep an eye on what your subscription costs after the IPO.

$349 versus $349 plus forever. For the first time, the no-subscription option isn’t a budget compromise. It’s the same price with a different philosophy about who owns your health data.
