The Circular Ring 2 is a premium smart ring that combines cutting-edge health monitoring with sleek, everyday wearability. Crafted in lightweight titanium at just around 2 grams, it’s designed for all-day comfort without sacrificing durability. It tracks over 140 biometrics—including heart rate, blood oxygen (SpO₂), skin temperature, sleep cycles, HRV, ECG readings and stress levels—to deliver deep wellness insights. With IP68 water and dust resistance and a compact wireless charging case, it’s built to handle life on the move while providing up to 7–8 days of battery life depending on usage mode. The companion app features an AI health strategist named “Kira” that analyzes your data in real-time and offers personalized guidance to optimise your rest, recovery and performance. A digital sizing tool lets you measure your ring size directly via smartphone, ensuring a precise fit without the hassle of mailed kits. The polished finish, minimal branding and refined engineering mean it looks like jewellery while functioning like advanced wearable tech. Compatible with both iOS and Android devices, it integrates seamlessly into your digital life. With no required monthly subscription for core features, it offers high-end health tracking without ongoing fees. The Circular Ring 2 represents the intersection of luxury design and proactive wellness in one elegant wearable.
