Quick verdict
Ultrahuman Ring PRO costs $479 with its PRO charging case, runs up to 15 days, and needs no subscription for core data. The catch is its PowerPlugs: meaningful extras like Afib detection and the Ultrahuman Card cost $4.90/month each. We break down the battery claim, the sizes and colours, and where it sits against the Oura Ring 4 and Samsung Galaxy Ring.
What is the Ultrahuman Ring PRO?
Ultrahuman Ring PRO is the company’s new flagship smart ring, replacing Ring Air as the line’s main product. It keeps Ring Air’s titanium build and the same PPG sensor stack (green, red and infrared LEDs), adds a faster Fighter Jet chipset and doubled onboard storage, and is aimed at one thing above all: battery life. It is a pure health and recovery ring — there is no screen, no speaker and no AI assistant on board, and Ultrahuman is clear that the PRO has no subscription for its core metrics: sleep, readiness, HRV, temperature and stress.
What the pricing page doesn’t make obvious
The $479 sticker is the price with the PRO charging case included; there is no cheaper ring-only option, and the case is not a PowerPlug extra. But the fine print that matters is PowerPlugs: Ultrahuman’s optional add-ons — including Afib detection, the Ultrahuman Card, and third-party data imports — are billed at $4.90 a month each. Core data is free, but the deeper features are not. And that headline “15-day battery” is a conditional number: Ultrahuman’s own numbers say 10–15 days depending on usage, so 10 days is the realistic floor, not 15. On sizing, the PRO’s 11 sizes run from 5 to 15; buyers should confirm their sizing-kit result before ordering, because a wrong size is the most common reason for a return.

Pros and cons
Pros
- 15-day battery is the longest in its class, and the case holds 10 charges
- No subscription for core health data — sleep, HRV, readiness and temperature are free
- Lightest flagship ring at 3.5–4.3 g, with 100 m water resistance
- Free sizing kit and 7-day return window
Cons
- PowerPlugs put real features behind a $4.90/month paywall — Afib detection is not included
- 15-day figure is a best case; Ultrahuman’s own range starts at 10 days
- No screen, speaker or on-ring controls — everything happens in the app
- $479 is $80 more than the Oura Ring 4’s $399 entry price
Who it’s for
Buy the Ring PRO if battery life is your top priority, you want the longest run between charges of any major smart ring, and you are happy to pay for PowerPlugs or skip them. Stick with the cheaper Ultrahuman Ring Air (from $349) if you want the same core metrics for less, or the Oura Ring 4 ($399) if you want the deepest sleep analysis and are fine charging every week.
