Last year, Luna introduced its Gen 2 smart ring. Now, the company is launching a major upgrade that will make the Ring “the world’s first wearable device you can literally talk to.”
In short, you can use voice commands to log the events of your entire day – what you ate, what you drank, what supplements you took, any workouts you did, even subjective feelings. Previously, you had to take out your phone to do this. That extra friction can cause you to put it off for later and forget to log important things.
Luna Ring Gen 2
The Luna Ring Gen 2 tracks all kinds of health metrics, starting with heart rate and heart rate variability. It also has a SpO2 monitor and a sleep tracker. A skin temperature sensor enables monitoring of women’s health and fertility.
And there’s a hydration reminder and caffeine window feature that keeps track of what you’ve logged. It won’t bother you if you’ve already drunk enough water, but it will remind you if you haven’t.
Luna Voice lets you track your day and ask health questions
Additionally, you can use the voice chat functionality to create workout and nutrition plans. You can use an AI coach to guide you during practice. After exercising, you can have a conversation with the AI about your health based on the data it collects. One hurdle on iOS is that you have to go through Siri to access Luna Voice AI (though it’s on Apple).
Depending on your usage, the ring has a battery life of 4-7 days. The charging case extends it to 30 days. The Ring takes 60-80 minutes in the case to charge, and once a month you’ll need to plug it into the case for two hours to charge its 580mAh battery.
You can use Ring with Android and iOS devices and there is no monthly subscription. The outside of the ring is PVD-coated titanium (available in four colors) and non-allergenic, non-metallic interior molding (around your finger). It is rated for 5 ATM water resistance (up to 50 meters).
You can purchase the Luna Ring Gen 2 from Luna’s online store for $330/£300.
“This marks a fundamental shift in wearables. The Luna Ring no longer simply measures the body. It senses context, links daily behavior to biometrics, and communicates in a way that naturally fits into real life.” said Amit Khatri, founder of Luna.
