Everywhere we look, we find screens attempting to catch our eye: phones, laptops, TVs, tablets and even our fitness trackers. Although we now have smart rings that lack screens and the screen-free Whoop 5.0 fitness-tracking wristband, both still require apps for logging your meals, mood and other events that can't be tracked from your wrist or finger.
Displayed at CES 2026, the Luna Band is something we haven't seen before: a screenless fitness and health tracker that doesn't require an app because it listens to your voice. Plus, there's no annual subcription.
From Luna Ring creator Luna, the company's new wristband uses your voice to log your health information. This is made possible by its AI engine, LifeOS, which is compatible with Siri and powered by Gemini.
The Luna Band is available in several colors, including gray, orange, dark blue and champagne. Luna
What can the Luna Band track?
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 perform and any extra symptoms you're experiencing. According to the company, the Luna Band can track all aspects of your health.

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.
