The HX3918 optical sensor monitors heart rate and supports HRV (Heart Rate Variability) and stress tracking — metrics derived from heart rate signal data recorded throughout the day and overnight. Blood oxygen saturation (SpO2) is recorded alongside sleep monitoring, which tracks sleep patterns and records exercise data. Female menstrual cycle tracking is also supported via the Da Rings app. Activity tracking records steps and movement data. GPS function uses the paired phone's GPS — the ring does not contain a built-in GPS module. The R100 is waterproofed to IP68 and weighs approximately 3.2g at 2.6mm thickness, available in sizes #8 through #13. The 18mAh battery provides approximately 6–8 days of normal use or approximately 15 days of standby, with a charge time of less than 60 minutes from the included charging case.

Blood oxygen saturation (SpO2) is monitored and recorded through the Da Rings app. Sleep monitoring tracks sleep patterns and provides sleep data via the app. Exercise records and activity tracking are supported. Female menstrual cycle tracking is available through the Da Rings app. All health monitoring data is displayed through the Da Rings app — the ring records and transmits sensor data; the app provides the display, history, and reporting interface. Health tracking features record and display data; they do not diagnose, treat, or replace medical devices or professional medical advice.\u003c\/p\u003e\n\u003ch4\u003eIP68 waterproof — 314 stainless steel — approximately 3.2g, 2.6mm thick\u003c\/h4\u003e\n\u003cp\u003eThe R100 is made from 314 stainless steel with an IP68 waterproof rating — suitable for submersion in water during daily activities. Submersion depth and duration limits for IP68 should be verified with the product documentation. Weight is approximately 3.2g and thickness is 2.6mm — designed for all-day wear. Sizes are available from #8 (18.2mm inner diameter) to #13 (22.2mm inner diameter). Operating temperature range is 0–50°C. CPU is AB2026B3 with 4Mb ROM and 96Kb RAM. The HX3918 optical sensor is positioned on the inner surface of the ring for continuous skin contact during wear.\u003c\/p\u003e\n\u003ch4\u003eBluetooth 5.3 — Da Rings app — 18mAh, 6–8 days battery\u003c\/h4\u003e\n\u003cp\u003eBluetooth 5.3 connects the R100 to paired smartphones for data sync and notifications. The Da Rings app is the companion application for all health data display, history, and ring configuration — download and set up Da Rings before use. GPS is app-based — the ring uses the paired phone's GPS rather than a built-in GPS module. The 18mAh battery provides approximately 6–8 days of normal use or approximately 15 days of standby per charge. Charge time is less than 60 minutes via the included charging case and charging cable.
