CES 2026: Luna Band puts voice tracking at the centre of health wearables
Luna rolled into CES 2026 with a health tracker that ditches screens and stats in favour of simple voice interaction. The Luna Band is all about speaking your health out loud and getting feedback the same way.
This isn’t the company’s first foray into wearables. Luna already dipped into the smart ring space with a budget-friendly release last year. Its new Band looks a bit like a Whoop, but it’s not just tracking for the sake of it. The focus is on real-time guidance, without needing to open an app or scroll through a dashboard.
A wearable that listens, not just tracks
Logging meals, moods, symptoms or emotional states can all be done with your voice. Responses arrive in the same format, through your earbuds or a connected phone. On iOS, it all runs through Siri integration. Android support hasn’t been confirmed yet, though Luna says that’s in development.
The emphasis here is on real-time feedback rather than daily summaries or weekly reports. The Band responds to what’s happening in the moment, using signals related to stress, sleep recovery, hormonal shifts, along with circadian patterns to shape its guidance.
The tech under the surface
The device runs on Luna’s own LifeOS platform. That name may sound a bit grand, but it refers to an operating system tuned for interpreting physiological data. LifeOS scans thousands of signals every minute, feeding them into a system designed to spot micro-recoveries, stress spikes, circadian shifts and emotional changes.
The sensor array includes a research-grade optical setup and a 6-axis IMU. That allows the Band to track movement and physiological changes with a level of fidelity more often found in lab equipment. Luna says this level of granularity allows for better predictions and more relevant feedback, particularly for daily stress patterns and sleep alignment.
Focused on habit, not data overload
What’s different here is the lack of a screen and the deliberate absence of traditional stats-on-demand. Luna isn’t targeting those who want to obsess over graphs. Instead, it’s for users who prefer to speak and listen rather than scroll and swipe.
This is also about reducing friction. By removing the need to even open the app, Luna hopes people will stick with the experience longer. Daily interactions become more natural, and the system nudges you when something looks off.
The Band connects to Luna’s mobile app for longer-term review, but most of the day-to-day happens through voice and prompts. The company says LifeOS also plays nicely with third-party services like Apple Health, Google Fit, Clue, and Kindbody, so your data can live in other ecosystems if needed.
The design will feel familiar to anyone who has used a Whoop strap or Amazfit Helio Strap. It’s a clean, screenless band with a metallic case that houses both the battery and sensors. Available colours are on the bold side, with options like hot red, orange, verdant green, and purple at launch.
Pricing is still under wraps, but Luna has confirmed that there will be no subscription fee. A formal release date hasn’t been set either, but the company says it will land later this year.
