Luna Ring Gen 2 gets Luna Voice feature for hands-free logging and access to AI advice

Luna is upgrading its second-generation smart ring with a major new feature called Luna Voice, transforming the wearable from a passive health tracker into an interactive device you can actually talk to. The company describes this as making the Luna Ring "the world's first wearable you can truly talk to," addressing a common friction point in health tracking where users had to pull out their phones to log meals, workouts, or subjective feelings.

The voice command system allows users to log various daily activities hands-free - what you ate, what you drank, supplements taken, workouts completed, and even subjective feelings about your day. This eliminates the barrier of having to manually enter data through a phone app, which often leads to skipped entries and incomplete health records. The ring's AI can then provide personalized health advice based on this logged information, creating a more comprehensive picture of your daily habits and their impact on your wellbeing.

Beyond simple logging, Luna Voice enables more sophisticated interactions. Users can create customized workout and nutrition plans through voice commands, receive AI coaching guidance during exercise, and engage in post-workout health discussions based on the biometric data the ring has collected. This creates a continuous feedback loop between your physical activity, the ring's sensors, and the AI's recommendations.

However, iOS users face a limitation - they must go through Siri to access Luna Voice AI functionality. This extra step is due to Apple's ecosystem restrictions rather than a limitation of the Luna Ring itself.

The Luna Ring Gen 2 maintains its comprehensive health tracking capabilities, measuring heart rate, heart rate variability, SpO2 levels, sleep patterns, and skin temperature. The temperature sensor enables women's health and fertility tracking features. The ring also includes practical wellness tools like hydration reminders and caffeine window tracking that adjust based on your logged intake.

Battery life remains competitive at 4-7 days depending on usage, with the charging case extending total usage to up to 30 days. The ring requires 60-80 minutes to charge in the case, while the case itself needs a two-hour charge once monthly to replenish its 580mAh battery. The device is water-resistant to 5 ATM (50 meters) and constructed with PVD-coated titanium available in four colors, with a non-allergenic inner molding for comfort.

The ring works with both Android and iOS devices and notably does not require a monthly subscription, making it more accessible than some competing smart rings that lock features behind ongoing fees. Priced at $330/£300, the Luna Ring Gen 2 is available through Luna's online store.

Founder Amit Khatri emphasized the significance of this update: "This marks a fundamental shift in what a wearable is. The Luna Ring no longer just measures the body. It understands context, connects daily behavior with biometrics, and communicates back in a way that fits naturally into real life."

The Luna Voice feature represents a growing trend in wearable technology toward more conversational, AI-powered interactions that reduce friction in health tracking and provide more actionable insights based on comprehensive data collection.
