The picks in detail
Amazfit Amazfit Helio Ring
Bottom line. The value pick, and the obvious choice if you already use an Amazfit watch and the Zepp app.
Pros
- No subscription - every feature unlocked at purchase
- Lightweight ~3g titanium with PVD finishes
- Strong battery (4-day typical, up to 7 at low polling)
- Zepp app integration is a real plus if you already own Amazfit gear
- Competitive mid-tier UK pricing - the cheaper of the two
Cons
- Zepp app lags Oura and Ultrahuman in polish and recovery-score depth
- Sleep-stage accuracy less well-validated independently
- No active spot-check SpO2 - overnight monitoring only
- Fewer sizes; sizing kit essential
RingConn RingConn Gen 3
Bottom line. The stronger all-rounder - longer battery, more sensors and a higher overall rating.
Pros
- No subscription - vascular insights included
- Class-leading 10-14 day battery
- Vibration motor for silent alarms; nighttime blood-pressure trend tracking
- Light titanium build, IP68
- Our highest-rated no-subscription ring of 2026
Cons
- Sleep-stage accuracy still trails the Oura Ring 4
- App less polished than subscription rivals
- Vascular and blood-pressure readings are trends, not clinical
- No longer the budget option
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.
