Ultrahuman Ring Pro Review

The Ring Pro is Ultrahuman's first major hardware overhaul since the Ring Air, and it reads as a confident, ground-up rethink rather than a minor refresh. The redesign was partly driven by necessity: the Ring Air was blocked from sale in the US after a patent dispute with Oura. The result is a ring that leans hard into endurance and long-term data, with a new dual-core processor handling machine learning on the device itself.

The headline appeal is how rarely you should need to think about charging. A rated 15 days on the finger, plus a charging case that holds a further 45 days, makes this one of the more travel-friendly wearables we've looked at on paper. It suits people who want passive, always-on health tracking without a daily or weekly charging ritual, and those who want to build up a long history of data for Ultrahuman's new Jade AI to analyse.

It is less obviously aimed at anyone who prioritises a slim, discreet ring or the lowest possible cost of entry. We weren't supplied with pricing, so we can't judge value directly, but multiple reviewers flagged it as expensive relative to competitors.

On the strength of the verified information, the Ring Pro looks like a meaningful step forward for Ultrahuman, with some caveats that keep it short of a must-buy.

• Endurance is the standout. Up to 15 days of battery plus 45 more from the case is a genuinely practical advantage, and the leap from four days of onboard memory to 250 days means you can go a long time without syncing and not lose data.
• Smarter internals. Moving from a single-core chip to a dual-core processor with on-device machine learning should give Ultrahuman more room for richer analysis. Jade, its AI built to draw conclusions from long-term health history, pairs naturally with that larger storage. We'd treat its usefulness as promising rather than proven, since the supplied claims describe intent more than results.
• Durable build. Titanium with a scratch-resistant PVD coating, waterproofing to 100 metres, four finishes and a broad 5-14 size range make it a sensible ring to wear all the time.
• Fair, if not fully free, software model. Core insights need no subscription, which compares well with subscription-dependent rivals. However, some metrics sit behind a subscription or paid Power Plugs add-ons, so the total cost depends on what you want to track.
• The trade-offs. Reviewers consistently described it as chunkier than the Ring Air and expensive compared with rivals. For a product worn day and night, bulk matters.

We're giving it a strong but not top-tier score. Our assessment rests on verified specs and third-party reporting rather than our own sensor-accuracy testing, and we have no confirmed price, so treat the value side of this verdict with some caution.
