Today, Luna has announced that its smart ring — the Luna Ring 2.0 can now be used via voice commands, allowing you to log workouts and have conversations with your ring about your sleep, stress, and recovery data. We haven’t yet seen a smart ring take this step, skipping the need to use an app to log your data.
We first saw this technology in January at CES 2026, when the brand also announced its Luna Band — a screenless wristband health tracker similar to the Whoop 5.0. There isn’t a launch date yet, but the band is expected to be released later this year.
In an attempt to move away from screens, Luna has added the ability to talk to its wearable using Siri. Users can now log events throughout the day, from what they ate for lunch to medication they’ve taken and workouts they’ve done, without picking up their phone.
Additionally, ring wearers can use the voice chat functionality to create a workout or nutrition plan. You can now say things like, "Hey Siri, ask Luna how my recovery looks after yesterday’s run," and Luna’s AI coach will respond, offering advice. Both iOS and Android users can talk to Luna Voice AI directly when they open the app, whereas iOS users can log their habits without opening the app, via Siri.

“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.”
The Luna Ring 2.0 is one of the best Oura alternatives on the market — it tracks all kinds of health metrics, including heart rate, stress, and sleep, and there’s a SpO2 monitor and skin temperature sensor on board too, allowing for women’s health and fertility tracking.
The ring has a battery life of 4-7 days, and the charging case that comes with it extends this to 30 days. There’s no monthly subscription, and the ring is compatible with Android and iOS. The Luna Ring Gen 2 costs $330/£300 and is available from Luna directly.
At the time of writing, the Luna Ring is not available in the U.S. due to an ongoing Oura suit with the U.S. International Trade Commission. As of November 2025, Oura filed a complaint against several smart ring manufacturers, which saw the likes of Ringconn, Luna, and Ultrahuman pausing trading in the country.
