Luna, the company behind the Luna Ring, has begun shipping its screenless fitness tracker, the Luna Band, worldwide. The move was revealed at IFA 2026, with pricing set at 149 USD (about 23,000 yen) in the United States and 149 EUR (about 27,000 yen) in Europe and other supported markets. The AI coaching features carry no monthly fee.

No display, so you talk to it instead

The Luna Band has no screen. That has been the design from the moment it first appeared at CES 2026 in January: rather than showing information on your wrist like a watch, it hands the interpretation of the data entirely to the phone app.

So how do you operate it? By voice. To log a meal or a supplement, you simply speak to the band. There is no tiny display to poke at, and no need to pull out a phone. You can also upload lab reports if you want them folded into your longer-term record.

A vibration motor inside the body handles alarms and prompts. With no display to read, the device leans on haptics to get your attention rather than asking you to look at anything.

24 grams, worn on the wrist or upper arm

The band weighs 24 grams and measures 40 mm long, 27 mm across the frame and 11.8 mm tall including the strap. It can be worn on the upper arm as well as the wrist. The nylon strap uses a hook-and-loop closure and comes in medium (around 240 mm) and large (around 295 mm) sizes, and straps are interchangeable.

Sensing is handled by an optical heart-rate array combining 4 photodiodes with green, red and infrared LEDs, plus a 6-axis IMU built from a 3-axis accelerometer and a 3-axis gyroscope, a skin temperature sensor and blood-oxygen measurement. On top of heart-rate variability, sleep and daily activity, it covers VO2 max, training load and heart-rate zones, with more than 60 sports modes. Running, walking, cycling, elliptical and rowing are detected automatically.

There is no GPS in the band itself, so routes rely on the connected phone. Water resistance is rated at 5 ATM, battery life runs up to 10 days, and a full charge takes 60 minutes with the included charger. Listed integrations include Apple Health, Google Fit and the cycle-tracking app Clue.

LifeOS builds the day around you

The hardware is only half the story. Luna pairs it with a software layer called LifeOS, which takes the readings and assembles an hour-by-hour plan for the day.

LifeOS ships with a set of Micro Apps covering caffeine timing, hydration, jet lag, fitness age and circadian rhythm. The more distinctive claim is that setting a goal changes what the band measures, how often it samples and what the daily calendar shows you. In other words, identical hardware is meant to produce a different experience depending on the person wearing it.

That said, this is the part that is hardest to judge on paper. The idea that behaviour shifts with your goal sounds appealing, but whether it translates into a difference you can actually feel will only become clear once reviews of shipping units arrive.

Where 149 USD sits in a crowded field

Screenless trackers have become busy over the past year. Google's Fitbit Air arrived at 99 USD (about 15,000 yen), Garmin's CIRQA Smart Band at 199 USD (about 31,000 yen), and WHOOP, long the dominant name in the category, still runs on a membership model.

At 149 USD, the Luna Band lands neatly between those two price points, and the coaching comes at no extra cost. For anyone tired of monthly payments, that is an easy proposition to understand. In the United States the 149 USD figure includes tax and delivery, and orders are listed as shipping immediately.

Getting here took an unusual route. The waitlist opened in May, pre-orders started on July 4, and the first units shipped on July 31, but that first drop was invite-only and sold out quickly. Luna says the waitlist attracted more than 100,000 people, which left everyone who missed the invite waiting for this worldwide rollout. Colour options are Onyx Black, Desert Beige and Aloe Green. Onyx Black and Desert Beige ship immediately, while Aloe Green is listed as shipping from September 7.

There is no separate announcement covering availability in Japan at this point. Orders go through Luna's own online store.

Summary

The Luna Band is a 24-gram fitness tracker that drops the display entirely and commits to voice control. It carries the expected sensor set for heart rate, blood oxygen and skin temperature, adds up to 10 days of battery and 5 ATM water resistance, and leans on the LifeOS coaching layer to reshape what it measures and advises based on your goal. The clearest difference against Fitbit Air and WHOOP is that nothing sits behind a monthly fee on top of the 149 USD price. How well it performs will only be visible once reviews of retail units start appearing.
