Health trackers without a screen seem to be increasingly trending since the Whoop band. In addition to the Whoop 5.0, manufacturers like Amazfit and Polar also offer similar solutions. At CES 2026, Luna, a subsidiary of the Indian tech company Noise, which has been more known for smart rings so far, introduced its Luna Band. Similar to the models from Amazfit and Polar, the tracker is intended to be usable without monthly subscription fees.
Siri Support
According to the company, the band is supposed to offer "real-time health advice via voice output." Furthermore, the Luna Band is not only supposed to display data but also provide timely and actionable suggestions. Users can also log meals, record symptoms, and seek health advice using voice commands with the band. According to the manufacturer, the system works via connected earbuds and integration with Apple's Siri. The manufacturer does not reveal on its website whether it works with other voice assistants; according to information from the British newspaper Independent, this should be the case.
The band looks similar to other products in this category: it has a slim metal casing containing the sensors and battery. The tracker collects health data and synchronizes it with the smartphone app, where users can view statistics and advice.

LifeOS as Operating System
On the software side, the fitness tracker is based on the company's proprietary operating system, LifeOS, which, according to the manufacturer, should be able to process thousands of physiological signals per minute. According to Luna, LifeOS recognizes changes in the areas of recovery, stress, circadian rhythm, and hormone patterns and provides context-aware recommendations throughout the day. In addition to daily activity, the band also provides insights into sleep patterns and can be used as a cycle tracker. Furthermore, according to the manufacturer, the band can measure recovery and stress.
The band contains optical sensors and a "high-precision 6-axis IMU" (Inertial Measurement Unit). The manufacturer does not provide further details about the equipment. Luna has not yet revealed a price either. The band is expected to be released later this year.
