It feels like today's wearables are limitless, tracking everything from our sleep and stress to our activity and recovery. Yet we haven't seen this one feature in smart rings or wrist-based fitness trackers.
Until now. Personal health tech company Luna just announced its Luna Ring Gen 2 as the world's first smart ring you can talk to. That means you won't have to use an app to log data that your wearable can't track on its own.
We spotted this technology during 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 also uses your voice and its AI engine, LifeOS, which is compatible with Siri and powered by Gemini, to track your health information.
As the Luna Ring Gen 2 is the only ring the brand currently sells, it is the only one available with Luna Voice. Since it's currently compatible only with Siri, only Apple users can use this feature.
Luna Voice is compatible with Siri and will answer your health questions through compatible earbuds or a smartphone. Luna
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 less 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. Luna
Plus, unlike other smart rings and wearables, the Luna Ring doesn't come with a subscription fee. Perhaps this is its greatest selling point.
