The Oura Ring 5 and the Ultrahuman Ring Pro are the two most serious smart rings for people who want real health data, and they split on one big question: subscriptions. The Oura Ring 5 (the latest ring from Finnish firm Oura) charges a monthly membership but offers the most trusted tracking; the Ultrahuman Ring Pro (from health-tech company Ultrahuman) costs more up front but never charges a fee and lasts far longer per charge.

The picks in detail
Oura Ring 5
Bottom line. The safer all-rounder - best app and most trusted accuracy, if you accept the membership.
Pros
- Dramatically smaller and lighter than the Ring 4 (about 40% smaller, 2-2.69g)
- Longer 6-9 day battery, up from 5-8 days
- New Blood Pressure Signals and Nighttime Breathing metrics on top of Oura's class-leading sleep tracking
- Optional charging case holds around a month of power for travel
Cons
- Oura Membership at £5.99/month (or £69.99/year) is still required for the full feature set
- £399 entry price rises to £499 for premium finishes
- Blood Pressure Signals show cardiovascular patterns, not a clinical blood-pressure reading
- No screen and a fixed size - you commit to one finger and need a sizing kit first

Ultrahuman Ring Pro
Bottom line. The subscription-free pick with the longest battery, for those who'll keep it for years. Currently on pre-order with limited UK availability.
Pros
- Category-leading 15-day battery life (more than 2x Oura Ring 4)
- No subscription required for core features or the Jade AI platform
- Titanium unibody construction + on-chip ML processor
- 250 days of on-device health data storage
- Four finish options (Bionic Gold, Space Silver, Aster Black, Raw Titanium)
- ProRelease emergency-cut safety feature
Cons
- £429 - premium price
- Independent polysomnogram accuracy data not broadly published as of mid-2026
- Production-delayed: official page shows pre-order as of July 2026, with limited UK availability
- Jade AI platform is genuinely new and unproven against Oura's longitudinal-data depth
What's the real difference?
Three things decide this one. Cost model: the Oura Ring 5 is £399 plus a mandatory £5.99/month membership; the Ultrahuman Ring Pro is £419 once, with no fees ever - so Ultrahuman is cheaper over any timeframe beyond the first few months. Battery: the Ultrahuman Ring Pro runs up to 15 days per charge against 6-9 for the Oura Ring 5, and its charging case adds a large buffer for travel. Accuracy: Oura's sleep and HRV tracking is the most validated in the category, repeatedly tested close to clinical polysomnography (overnight sleep-lab monitoring); Ultrahuman's accuracy rests mainly on its own published validation, with less broad independent confirmation so far.
Both rings work fully on iPhone and Android, and both are titanium, so the choice really comes down to whether you value Oura's trusted app or Ultrahuman's no-subscription, long-battery hardware.
Is no subscription worth giving up Oura's app?
Over three years, Oura's membership adds roughly £215 to the £399 ring, pushing its true cost well above the Ultrahuman Ring Pro's one-off £419. If lifetime cost and battery life are your priorities, Ultrahuman wins comfortably.
What you give up is maturity. Oura has years of refinement in its app, its readiness and sleep scores, and the largest body of independent accuracy testing. If you want the most trusted numbers and the most polished daily experience, that is still Oura - and the membership is the price of it.
