Amazfit Helio Ring vs SHR K3 — Smart Ring Privacy Comparison (Both China-Mfg)

Updated 2026-05-04 · Auditor: Tomás Maria Vaz de Noronha · Methodology: 3-pass forensic

TL;DR. Both rings are manufactured in China. Amazfit Helio runs through ZeppApp + optional Zepp Aura subscription. No public independent PCAP audit. SHR K3 (€129, Tier C Ainode audited) has a published packet capture, traffic-flow disclosure, and 6-dimension scoring — at less than half the price. For China-mfg buyers wanting the ring with audit transparency, SHR K3 is the only published-PCAP option.
