The Luna Band Uses Your Voice to Track Your Health, Giving You One Less Screen to Stare At

We live in a world full of health and fitness trackers, and as a consequence, more screens are battling for our attention. Yes, there are screen-free smart rings, such as the Oura Ring, and the Whoop 5.0, a performance- and recovery-tracking band, but these still require apps. 

Now, the Luna Band, introduced at CES 2026, could eliminate screens entirely by relying solely on your voice, not your scrolling fingers. 

From the creator of the Luna Ring, Luna's new wristband uses your voice to log your health information, assisted by its AI engine, LifeOS, which is compatible with Siri. Nina Raemont, a wearables and health tech editor at CNET's sister site ZDNET, reported on the voice-based health tracking device revealed at the annual tech show on Monday.

While traditional fitness trackers collect as much information as possible while on your wrist -- heart rate, temperature and activity level -- they lack the context only you can provide. For instance, while a tracker may detect that you got less quality sleep one night, it wouldn't know why unless you logged that information yourself.

Health trackers also typically require you to log additional lifestyle factors that they can't detect from your wrist, such as your mood, meals, the type of workouts you performed and any extra symptoms you're experiencing. According to the company, the Luna Band can track all aspects of your health. 

But what happens when you want to learn more about your health metrics, something you'd typically check an app for? The Luna Band still tracks activity, stress, sleep and more with its motion and optical sensors, but it delivers this information through a compatible smartphone or earbuds. The LifeOS AI, compatible with apps such as Apple Health, Google Fit and the period-tracking app Clue, can also answer any health-related questions you may have. 

The best part? The Luna Band doesn't require a subscription like the Whoop 5.0, which costs between $149 and $359 per year. There's no word on the cost or availability of the band, but the fact that you won't have to pay for it annually could make it a worthy competitor to other wellness trackers on the market.
