How we compiled this
Ten smart ring models were independently re-verified against official manufacturer product pages (ouraring.com, samsung.com, ultrahuman.com, ringconn.com, shop.circular.xyz, us.amazfit.com, eviering.com, lunazone.com) and reputable reviews (TechAdvisor, Tom's Guide, Android Authority, Wareable, Notebookcheck, NBC Select). weight_g reflects the range across available ring sizes (smallest to largest); battery_days is the manufacturer-claimed maximum under typical conditions; water_resistance_m is the stated/derived depth in meters where a depth or ATM figure is published (10ATM is treated as ~100m static rating). Where a manufacturer only publishes an IP rating (e.g. IP68) with no depth-in-meters spec, water_resistance_m is set to null rather than inventing a depth. subscription_required is true only when accessing core health insights requires an ongoing paid membership (Oura only). All accessedAt and generatedAt = 2026-06-15.
