Luna has upgraded its Luna Ring Gen 2 with Luna Voice, enabling hands-free voice commands for logging daily activities and accessing AI health advice. The smart ring now lets users log meals, workouts, supplements, and even subjective feelings through voice instead of manually pulling out their phone. This eliminates the friction that often causes people to skip logging important health data.

Beyond voice logging, the ring offers comprehensive health tracking including heart rate, SpO2, sleep monitoring, and skin temperature for women's health and fertility tracking. The Luna Voice feature also provides AI coaching during workouts and allows users to chat with the AI about their health data afterward. On iOS devices, users must route through Siri to access the voice AI functionality.

The ring offers 4-7 days of battery life with a charging case that extends usage to 30 days. Priced at $330/£300, it's compatible with both Android and iOS without requiring a monthly subscription. The ring features PVD-coated titanium in four colors and is rated for 5 ATM water resistance up to 50m.
