Ultrahuman vs Oura: Ring PRO against Oura Ring 5, side by side

Ultrahuman vs Oura: which ring should you buy?

Choose Ultrahuman Ring PRO if you want to pay once. It’s $479 with the PRO Charging Case included, and Ultrahuman says there are no recurring subscription fees for accessing your data¹³. Choose Oura Ring 5 if you want the thinner ring (2.28 mm against 2.65 mm). It’s $399, plus $5.99 a month or $69.99 a year for the membership, so three years come to $608.97 before tax^{4, 6}.

Ultrahuman rates Ring PRO at up to 15 days a charge, against 6 to 9 days for Ring 5^{1, 13}. The catch with Ring PRO is that Ultrahuman publishes no accuracy figures for it, and some features are paid PowerPlugs^{13, 14}. The catch with Ring 5 is that without a membership the app shows only three daily scores⁴. Neither maker’s figures show better sleep or any health effect.

Ultrahuman or Oura: which one fits which need

Each suits a different need, and this isn’t a ranking. Start with whether you’ll keep paying a fee, then check your ring size.

• You want to pay once and charge rarely: Ultrahuman Ring PRO. It’s $479 with the case included, and Ultrahuman rates it at up to 15 days a charge¹³. The catch: no accuracy figures, a 12-month warranty that excludes batteries, and some features sold as PowerPlugs^13–15.
• You want the thinner ring and Oura’s app, and you accept a yearly fee: Oura Ring 5. It’s $399 and 2.28 mm thick against Ring PRO’s 2.65 mm, and Oura’s accuracy claims point to published studies^{1, 6, 8}. The catch: $69.99 a year, three days of on-ring storage and whole sizes 6 to 13 only^{2, 4}.
• Your finger needs size 5 or 14: Ultrahuman Ring PRO. Oura Ring 5 stops at 6 and 13^{2, 13}.

Ultrahuman vs Oura: what three years costs

Ultrahuman Ring PRO costs $479 for three years, with no required fee¹³. Oura Ring 5 is $399 plus three yearly payments of $69.99, which is $608.97 before tax^{4, 6}. That leaves Ring PRO $129.97 less. Paying Oura monthly at $5.99 comes to $71.88 a year, or $614.64 over three years, and the free first month for new members isn’t deducted^{4, 5}.

The gap narrows if you add Ultrahuman’s extras. The optional Max membership is $99.99 for one year and includes PowerPlugs and UltrahumanX coverage¹³. If it renewed at that price, three years of Max would bring Ring PRO to $778.97, which is $170 above Oura Ring 5¹³. Ultrahuman says UltrahumanX isn’t an insurance program¹⁵. Oura’s optional protection upgrades, $45 for 2 years or $60 for 3, aren’t in either total⁶.

Neither total includes tax, shipping, charger electricity or a replacement battery. Neither maker states charger power draw or a battery replacement price. For Oura’s current price and Black Friday history, see Oura Ring Black Friday 2026.

Does Ultrahuman have a subscription like Oura?

No required one. Ultrahuman says there are no recurring subscription fees for accessing your data¹³. It does sell optional PowerPlugs, such as Cardio Adaptability at $24 for one year or $38 for two, and Cycle & Ovulation Pro at $39 for one year or $69 for two¹³. The optional Max membership is $9.99 a month or $99.99 for one year¹³.

Oura requires a membership for most insights after the first included month, at $5.99 a month or $69.99 a year^{4, 5}. Without one, the app shows only the Readiness, Activity and Sleep scores, ring battery, basic profile information, app settings and Explore content⁴. Oura says the membership belongs to your account, not the ring, and you can still export your data as a CSV file without one^{2, 4}. Plans, cancelling and refunds are on our Oura membership cost page.

Battery, sizing and fit

Ultrahuman rates Ring PRO at up to 15 days, about 12 in Turbo Mode, and up to 45 days between wall charges with the case. A full charge takes about 2.5 hours^{13, 14, 16}. Oura rates Ring 5 at 6 to 9 days, depending on ring size and usage, with about 80 minutes to charge^{1, 2}. Oura’s fast charge, a full day in 10 minutes, needs the Charging Case, which is sold separately¹. Ring PRO charges only on its own PRO Charger or case, not a Ring AIR charger¹³.

Ring PRO comes in whole sizes 5 to 14, and Ring 5 in whole sizes 6 to 13^{2, 13}. Both makers offer a free sizing kit before you order^{3, 13}. Oura says to wear its kit for at least 24 hours and that the index finger gives the best accuracy^{3, 6}.

On fit, Ring 5 is 2.28 mm thick and from 2 g, and Ring PRO is 2.65 mm thick and 3.3 to 4.8 g^{1, 13}. Ultrahuman doesn’t state band width or per-size inner diameter, so width can’t be compared¹³. Both are titanium and rated to 100 m^{1, 13}.

Ultrahuman and Oura warranty and returns

Ultrahuman gives Ring PRO a 12-month limited warranty for defects in materials and workmanship, valid only in the country of purchase¹⁵. It excludes batteries unless a defect caused the failure¹⁵. Those terms name Ring AIR, not Ring PRO, and the Ring PRO FAQ confirms only the one-year length^{14, 15}. Accidental damage, loss and theft support is listed only with the Max membership¹³.

Oura includes a 1-year protection plan and sells upgrades to 2 years for $45 or 3 years for $60⁶. Its product page doesn’t say what the plan covers, such as battery wear, scratches or loss⁶.

Both take returns within 30 days. Ultrahuman covers return shipping and wants the original packaging and accessories back^{14, 15}. Oura refunds the original payment method but not original shipping, handling or customs fees, and allows each item one return or exchange⁷. Oura says to cancel the membership when you return the ring⁷.

Can you buy Ultrahuman and Oura rings in the US?

Yes for both, on different footing. Ultrahuman’s US store listed Ring PRO for sale on October 23, 2026¹³. In August 2025 the US International Trade Commission (ITC) issued an exclusion order against Ultrahuman rings that infringe an Oura patent, after finding that Ring AIR did¹⁸. In March 2026 US Customs ruled that Ring PRO’s redesigned unibody ring falls outside that order, and each import needs a certification Customs approves¹⁷. A conflicting ITC decision would override the ruling, and TechCrunch reported on March 24, 2026 that Oura was weighing appeals^{17, 19}. On Oct 23, 2026 Oura announced a new patent suit over Ring PRO in the Eastern District of Texas, and no court has ruled on it²⁰.

Oura isn’t barred. In January 2026 the ITC opened Samsung’s patent case seeking to bar imports of Oura wearables (Investigation No. 337-TA-1478)¹⁰. The ITC’s notices through October 26, 2026 show the case still open, with no violation finding or exclusion order^{11, 12}.

What the accuracy claims don’t settle

Oura states 99% heart-rate accuracy against ECG and 95% two-stage sleep staging against a sleep lab, but its blog traces the heart-rate figure to a 2020 study of an earlier ring⁸. A 2021 study of an Oura research ring against polysomnography found 96% accuracy for sleep versus wake and 79% for four stages⁹. It tested an earlier ring, not Ring 5⁹.

Ultrahuman publishes no accuracy figures for Ring PRO and says it isn’t a medical device¹⁴. We found no independent study of either current ring. If accuracy decides it for you, neither maker gives you the evidence yet.
