4.0 / 5
☆☆☆☆☆
★★★★★
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 around £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
