Fitbit Air’s first update is already rolling out, and it could finally fix its biggest annoyance

At a glance:\n- Google has begun rolling out the first firmware update for Fitbit Air, version 20001.253.2 (iOS) / 67.20001.253.2 (Android).\n- The update focuses on bug fixes, performance improvements, and hints at expanded automatic workout detection.\n- Rollout is gradual; users will see a notification in the Google Health app when the firmware becomes available.\n\n## Why the update matters\nFitbit Air has been a popular entry‑level tracker since its launch, but early users have complained that the device struggles to recognize when they are exercising. The new build, announced by Google last month, promises to broaden the range of activities the tracker can automatically detect. If the update delivers on that promise, it could resolve the most common frustration that has kept some buyers from fully embracing the device.\n\nThe firmware also arrives at a time when Google has been expanding its Health platform. New wellness features, such as nap tracking, additional health metrics, and more granular controls over health data, have been added to the ecosystem. While those additions focus on the broader platform, this update is aimed squarely at improving the core functionality of the Fitbit Air itself.\n\n## What's new in the firmware\nGoogle has not released a detailed changelog, but the update is identified as version 20001.253.2 on iOS and 67.20001.253.2 on Android (h/t: 9to5Google). The two packages contain the same code, with only the numbering differing to match each operating system’s conventions. Both updates promise bug fixes and general performance improvements, and they hint at an expanded set of automatically detected exercises.\n\nIn addition to the usual reliability patches, the update could finally address the tracker’s biggest early complaint: automatic workout detection. A fitness tracker should log a workout when you’re moving and stop logging when you’re resting. The new firmware aims to make that detection more accurate, so users won’t need to manually start or stop sessions for walks, bike rides, or quick gym sessions.\n\n## How to get the update\nUsers will see a notification inside the Google Health app when the firmware becomes available for their Fitbit Air. The rollout is still in its early stages, so not every device will receive the update immediately. Availability is expected to expand over the next several days as Google rolls the new build to more users. To check for the update, open the Health app, tap "Devices", select your Fitbit Air, and follow any prompts to install the latest firmware.\n\nThe update is part of Google’s broader strategy to keep Fitbit devices competitive in a crowded market. By improving core features like automatic workout detection, the company hopes to increase user engagement and retention for its low‑cost, entry‑level trackers.
