This Fitbit Air rival skips a monthly subscription, and it finally has a launch date

May 25, 2026

The Luna Band is being positioned as a direct rival to Fitbit Air, but with one big difference: it appears to avoid the monthly subscription model. It is a screenless, voice-first wearable built around Luna’s LifeOS software, which aims to turn health data into practical daily guidance rather than just raw stats.

The device can track activity, sleep, stress, and other health signals, and it also lets users log food, supplements, symptoms, and even bloodwork-related information. Voice integration with assistants like Siri is a major part of the concept, so users can enter updates without opening the app.

Battery life is said to reach up to 10 days, and the design looks broader and more band-like than Fitbit Air, closer to a Whoop-style form factor. The overall pitch is that it offers a more flexible and potentially cheaper alternative for people who want continuous health tracking without recurring fees. Android Authority
