The picks in detail
RingConn Gen 3
Bottom line. The stronger all-rounder - longer battery, more sensors and a higher overall rating.
Pros
- First smart ring with built-in haptic motor (vibration alerts for elevated HR, inactivity, step goals)
- Nighttime blood-pressure trend tracking - new metric class for the category
- 10-14 day battery life across the category's longer-lived end
- No subscription required - all features included with hardware
- Universal wireless charging case (size-agnostic) replaces Gen 2's awkward size-specific charger
- Titanium build with medical-grade epoxy interior
- 10 ATM water resistance (shower + swim compatible)
Cons
- £309 price closes the value gap vs Oura Ring 4 (£349 hardware) - no longer the budget no-sub pick
- Nighttime blood pressure tracking is trend-only, not clinical-grade or medically validated
- Haptic motor reduces battery life from 14 to 10-12 days when active
- Independent polysomnogram + chest-strap HRV validation data not yet published (CES 2026 launch)
- UK retail availability still building in mid-2026

Amazfit Helio Ring
Bottom line. The value pick, and the obvious choice if you already use an Amazfit watch and the Zepp app.
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
Which one should you buy?
The RingConn Gen 3 is the stronger ring on the metrics that matter most - it is our highest-rated no-subscription ring of 2026, with a class-leading 10-to-14-day battery and extra sensors (vascular and nighttime blood-pressure trends) the Amazfit lacks. If you want the most capable ring of the two and don't mind paying mid-tier money, it is the pick.
The Amazfit Helio Ring makes sense for two buyers: the budget-conscious, since it is the cheaper of the two, and existing Amazfit-watch owners, who get genuine value from the shared Zepp app. It is lighter at around 3g, but its app is less polished and its sleep accuracy is less well-validated than the category leaders.
How do battery and sensors compare?
Battery is the clearest gap: the RingConn Gen 3 runs 10 to 14 days, well beyond the Amazfit's typical 4 (up to 7 at low polling). On sensors, the RingConn adds vascular and blood-pressure trend tracking the Amazfit doesn't offer, and the Amazfit limits SpO2 to overnight monitoring with no active spot-check. Both track sleep, heart rate and HRV, and both trail the Oura Ring 4 on sleep-stage detail - as most rings do, given a smart ring works from finger-mounted optical sensors rather than clinical-grade hardware.
Which app ecosystem suits you?
This often settles it. If you already wear an Amazfit watch, the Helio Ring feeds the same Zepp app and the combined picture is genuinely useful - that ecosystem fit can outweigh the RingConn's spec lead. If you have no existing Amazfit gear, the RingConn's standalone app and longer feature set make it the more future-proof choice.
