Oura Ring 5 vs Ultrahuman Ring PRO

Ring PRO is the older design here: Ultrahuman introduced it on 27 February 2026, three months before Oura’s Ring 5 arrived on 28 May 2026. In the US, though, PRO is the one you have to wait for.

Getting one in the US

Oura Ring 5 is a regular item in Oura’s US store. Ring PRO’s US story doesn’t add up yet: Ultrahuman’s 27 February 2026 launch post excluded the United States, its US buy page now takes pre-orders that ship from 10 October 2026, and on 22 September 2026 Amazon had a listing up for Aster Black in size 9. Until those agree, get a delivery date from Ultrahuman or the retailer before you plan around it.

Battery, case and storage

This is PRO’s strongest argument. Ultrahuman claims up to 15 days a charge under its own test conditions; Turbo mode cuts that to about 12, and Chill mode stretches it past 15. Ring 5’s typical range is 6 to 9 days by Oura’s figures, and it refills in about 80 minutes on its dock.

PRO’s charging case comes in the $479 bundle and adds up to 45 days. You can charge the case on a Qi charger at 5 watts or by USB-C. It connects to the ring through UltraSnap pins and has a speaker so you can find it when it goes missing. The box also has the charger and a 1 meter USB-C cable. Oura’s case for Ring 5 is an add-on, not part of the $399 price.

Storage is lopsided too. PRO keeps up to 250 days of data in its internal and external flash, and Ultrahuman separately quotes up to a year of data with the case in Chill mode. Ring 5 keeps up to 3 days. On a long trip without your phone, that gap matters; if you sync every day, you won’t notice it.

Membership or PowerPlugs

Ring 5’s Silver and Black finishes cost $399 and the other four $499, and then there’s Oura Membership, free for a new member’s first month and $5.99 a month or $69.99 a year after that. Without it you’re left with three daily scores. Ring PRO costs $479, and Ultrahuman’s US FAQ says core ring data carries no recurring fee.

That doesn’t make all of Ultrahuman’s app free. PowerPlugs are paid add-ons, such as Cardio Adaptability at $24 a year and Cycle and Ovulation Pro. Ultrahuman’s US page also showed up to $115 off with a trade-in, and financing at $120 a month; neither changes the $479 price. Oura’s store switched between dollars and euros on 19 September 2026, so look at the currency, and both carts, before you buy.

Size and fit

Ring 5 is the thinner ring, 2.28 millimeters against PRO’s 2.65, and Oura gives it a 6.09 millimeter width, a 0.7 millimeter dome and a starting weight of 2 grams; Oura also puts Ring 5’s volume 40 percent under Ring 4’s. PRO’s thickness varies by size, and it weighs 3.3 to 4.8 grams. Ultrahuman doesn’t give its width.

The size runs overlap without matching. Ring 5 comes in 6 through 13; PRO comes in whole sizes 5 through 14. A size 5 or 14 means PRO, and a 4 or 15 fits neither.

PRO’s shell mixes titanium with PVD, epoxy and polycarbonate, with plastic and titanium on the inside, and comes in Bionic Gold, Space Silver, Aster Black or Raw Titanium. Ultrahuman also builds in ProRelease, which it says lets the ring be cut off more easily if a finger swells. Ring 5’s shell is solid titanium, inner surface included, under a superhard PVD coat.

Sensors, water and phones

PRO uses a redesigned PPG sensor, a temperature sensor, a 6-axis motion sensor and a dual-core processor, and Ultrahuman pitches it at deep sleep, recovery and performance tracking rather than navigation; neither ring stands in for a GPS watch. Ring 5 pairs two triple LEDs with two photodetectors, an accelerometer and a temperature sensor; Oura’s launch post talks of 12 signal pathways. The ring spots 40-plus activities by itself, and its detailed sleep needs membership. Neither is a diagnostic tool: Oura says Ring 5 isn’t meant for diagnosis or treatment, so take any worrying reading from either ring to a clinician.

Water resistance is 100 meters (328 feet) on both. Oura adds IP68 and allows the sauna, swimming and recreational snorkeling, but not diving, scuba or more than 12 hours underwater. Oura gives Ring 5 an operating range of −10 to 54 °C, while its general FAQs say −10 to 52 °C.

For Ring 5 you need a phone with Bluetooth 5.0 running iOS 16 or later, or Android 11 or later with Google Play. PRO runs Bluetooth Low Energy 5.3, but Ultrahuman doesn’t list which iOS or Android versions it supports.
