The Luna Band, a screenless health tracker priced at 150 euros, was first showcased at the start of the year during the Consumer Electronics Show (CES) and later launched globally at IFA, a major tech trade fair. It aims to compete with established products like Google's Fitbit Air and Garmin's Cirqa Band by using voice AI technology. The Luna Band is entering a competitive market with a bold approach: offering a voice-controlled fitness tracker without a screen, challenging well-known brands like Garmin, Fitbit, and Polar. As a product from Noise, an Indian tech company known for its smart rings, the Luna Band was strategically chosen to debut at IFA after a period of limited availability, including an open waiting list in the spring and a restricted "Drop 1" release in July. Unlike traditional fitness trackers, the Luna Band does not have a built-in microphone or voice response system. Instead, it works with Apple's Siri on iPhones, allowing users to log meals, report symptoms, or ask questions through the LifeOS app without opening it. Voice interactions happen through the phone or connected headphones, while the bracelet communicates primarily through vibrations. The app is compatible with Android devices, but the Luna Band does not clearly explain how to achieve the same hands-free voice experience as with Siri. The device uses a combination of sensors, including an optical PPG sensor for heart rate, a skin temperature sensor, and a six-axis inertial measurement unit to track steps, sleep, and other metrics. It promises up to ten days of battery life, water resistance up to 5 ATM, and support for over 60 sports profiles, though only five are automatically recognized. GPS for outdoor activities depends on the user's smartphone. Priced at 149 euros, the Luna Band sits between Google's Fitbit Air (99 euros) and Garmin's Cirqa Band (200 euros), while also competing with the Amazfit Helio Strap and the Polar Loop. While the price appears reasonable, it raises questions about whether the voice AI feature can truly match the mature software ecosystems of established brands. Another selling point is the lack of monthly subscription fees, unlike models from Google and Garmin, although some advanced features on Fitbit require a paid subscription. The Luna Band is currently only available through the manufacturer's website in three colors: green, black, and beige. The global launch at IFA marks a shift from the company's earlier strategy of limited pre-orders to a more open distribution model. This move highlights Noise's ambition to expand its presence in the wearable technology market, leveraging the Luna Band's unique design and features to carve out a niche among established competitors.
