This is a premium-versus-budget contest. The Oura Ring 5 is the most polished smart ring on the market and charges accordingly, including a monthly membership. The Amazfit Helio Ring undercuts it heavily and asks for no subscription at all. The question is whether Oura's extra refinement justifies several times the long-term cost.

The picks in detail
Oura Ring 5
Bottom line. The premium pick: the most refined app and sleep insights, the slimmest fit, but a higher price and an ongoing 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

Amazfit Helio Ring
Bottom line. The budget pick: solid sleep and recovery basics with no subscription, at well under half the long-term cost.
Pros
- Genuinely no subscription required - all features available with one-time purchase
- Strong battery life (4-day typical, up to 7 days at lower polling)
- Lightweight titanium build (around 3g) with multiple finish options
- Integrates with the existing Zepp app ecosystem if you already own Amazfit watches
- UK availability via Amazon and Amazfit direct - from £149.90 after a big 2026 price cut (launched at £279)
Cons
- Zepp app is functional but lags Oura's and Ultrahuman's UX polish
- Sleep-stage detection is less validated than Oura's in independent comparisons
- No active SpO2 spot-check; only continuous overnight monitoring
- Limited third-party-app integration vs Oura (Apple Health / Google Fit only)
- Fewer ring sizes available than competitors - confirm fit with sizing kit first
How big is the price gap really?
Larger than the sticker prices suggest. The Oura Ring 5 is around £399 and most of its value sits behind the Oura Membership at roughly £5.99 a month, which brings the three-year cost to about £615. The Amazfit Helio Ring launched at £269 and Amazfit has since cut it much further - £149.90 direct at uk.amazfit.com as of July 2026 - with no recurring fee, so it stays at its purchase price for the life of the ring.
That makes the Amazfit comfortably less than half the three-year cost of the Oura. For buyers focused on value, that gap is the headline. Our subscription cost comparison shows how the membership compounds over time.
What do you give up by going budget?
Mainly polish and depth. Oura's app is the most mature in the category, with readiness scoring, detailed sleep staging and long-term trends that the Amazfit app does not match in sophistication. The Helio Ring covers the fundamentals well, particularly sleep, but its insight layer is simpler and its ecosystem less developed.
You also give up some refinement in fit and finish. The Oura Ring 5 is around 40% slimmer than before and one of the most discreet rings available, whereas the Helio is a chunkier, more conventional design. If you mostly want clean sleep and recovery numbers without paying monthly, the trade is reasonable; if you want the most insightful experience, Oura still leads.
Which is better for sleep tracking?
Oura is the stronger sleep tracker overall thanks to its staging and interpretation, but the Amazfit Helio Ring is widely regarded as a capable budget sleep ring and is often recommended specifically when sleep is the priority and budget is tight. Both give you nightly sleep data; Oura simply does more with it. For a deeper look at how rings measure sleep, see our sleep-stage accuracy guide.
Which should you actually buy?
Buy the Oura Ring 5 if you want the best-interpreted health data, the slimmest fit and a steadily improving app, and you accept the ongoing fee. Buy the Amazfit Helio Ring if you want solid, subscription-free tracking at a low price and you are comfortable with a simpler app. For most budget-conscious first-time buyers the Amazfit is the sensible entry point; for data enthusiasts the Oura earns its premium.
