There's a lot your smart ring or fitness tracker can do from your finger or wrist, but there is still certain information you have to manually log yourself in the app. Think meals you've eaten or the exact type of exercise you've completed. Until now.
On Thursday, health tech company Luna announced that its Luna Ring Gen 2 became the world's first smart ring you can talk to about your health. This is thanks to Luna Voice and the company's AI engine, LifeOS, which is powered by Gemini and compatible with Siri, meaning only Apple users can use this feature.
As the Luna Ring Gen 2 is the only ring the brand currently sells, it is the only one available with Luna Voice.
CNET spotted this technology at CES 2026, when Luna unveiled its Luna Band, a wristband health tracker similar to the Whoop 5.0 in that it doesn't have a screen. Like the Luna Ring, the band can also use your voice and its AI engine to track your health information.
Luna Voice is compatible with Siri and will answer your health questions through compatible earbuds or a smartphone.
Now, you can tell your smart ring when you eat a meal, take a supplement, drink a cup of coffee or when you just went for a run, so it knows what type of activity it picked up from your finger. You can also ask it questions about your health, and it will respond through a compatible smartphone or earbuds.
You won't need to open your app to add this information yourself, giving you one fewer screen to check.
“This marks a fundamental shift in what a wearable is,” Luna founder Amit Khatri said in a press release. “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.”
In a world full of screens, not having to log data your smart ring can't track is a welcome sight.
Plus, unlike other smart rings and wearables, the Luna Ring doesn't come with a subscription fee. Perhaps this is its greatest selling point.
Here's the catch
While the Luna Ring Gen 2 is priced at $329, it's not available in the US right now. This is a recent development, as on Nov. 19, Oura, makers of the Oura Ring, filed a complaint with the US International Trade Commission against Samsung, Reebok (for the Reebok Smart Ring), Zepp Health (for the Amazfit ring) and Nexxbase (owners of the Luna Ring), stating that the companies are unlawfully importing and selling products that infringe on Oura Ring patents.
On Jan. 8, Luna Ring maker Nexxbase consented, stating that it would voluntarily stay out of the US.
A representative for Luna told CNET that it is working toward once again making the ring available in the US in the next couple of months. As for the Luna Band, presales will go live in April with the launch planned for the end of May.
