You lace up your sneakers, head out for a morning run, and come back feeling great. But when you check your Fitbit Air later, the tracker shows nothing. No run logged. No calories burned. No record of your effort. If you own a Fitbit Air, this scene might feel all too familiar.
Automatic workout detection was supposed to be one of the handiest features on Google’s latest fitness tracker. Instead, it became one of the biggest frustrations for early buyers. The device often missed workouts entirely. Sometimes it logged a false activity when you were just walking to the bus stop. Either way, the tracking felt unreliable.
Now Google is finally doing something about it. The company has started rolling out the very first Fitbit Air firmware update since the device launched. And the fix everyone has been waiting for might finally be here.
The Biggest Annoyance: Why Automatic Workout Detection Matters
Automatic workout detection is the feature that lets your fitness tracker figure out when you’re exercising without you having to tap any buttons. You just start moving, and the device recognizes the activity and begins tracking it. It sounds simple, but getting it right is surprisingly hard.
The Fitbit Air uses a combination of sensors to guess what you’re doing. It has an accelerometer to measure motion and an optical heart rate sensor to track your pulse. The device’s software looks at patterns in that data and compares them to known exercise profiles. If your arm swings a certain way and your heart rate goes up, the tracker might decide you’re running. If you’re moving more slowly and your heart rate stays low, it might think you’re walking.
But in practice, the algorithm made mistakes. Early reviews and user reports on forums like Reddit and the Fitbit Community highlighted two main problems. First, the Fitbit Air often failed to detect workouts at all. Users would finish a bike ride or a swim and find no record in the Google Health app. Second, the device sometimes triggered false detections. A user might get a notification congratulating them on a brisk walk when they were actually just carrying groceries.
For a fitness tracker, accurate workout logging is a core function. If the device can’t reliably tell when you’re exercising, you lose trust in the data. You might start manually starting workouts, which defeats the purpose of an automatic feature. Or worse, you might stop using the tracker altogether.
Google acknowledged the problem shortly after launch. In a statement covered by Android Authority, the company said it was working on improvements to automatic workout detection. But until now, users had no timeline for when those fixes would arrive.
What’s in the Fitbit Air Firmware Update? Version Numbers and Bug Fixes
The new software is rolling out now as a firmware update. Firmware is the low-level software that runs on the Fitbit Air itself, separate from the Google Health app on your phone. Updating the firmware changes how the device behaves and can fix bugs that the app alone can’t address.
According to 9to5Google, which first spotted the update on June 25, 2026, the version numbers look slightly different depending on which phone you use. On iOS devices like the iPhone, the update is version 20001.253.2. On Android phones, it’s version 67.20001.253.2. Both numbers refer to the same software package. The difference is just how the Google Health app labels it for each operating system.
Google hasn’t published a detailed changelog, but the company says the update includes “bug fixes and general performance improvements.” More importantly, the update is expected to deliver the previously promised improvements to automatic workout detection. That means the algorithm that decides when you’re exercising should be smarter and more accurate.
It’s not clear exactly what Google changed under the hood. The company hasn’t explained whether it tweaked the sensor thresholds, added new activity profiles, or improved the machine learning model. But the timing suggests this update is directly aimed at the biggest complaints from early adopters.
Other bugs are likely being fixed too. Early reviews noted occasional issues with syncing data between the Fitbit Air and the Google Health app. Some users reported that their step counts would disappear after a restart. Others saw incorrect heart rate readings during workouts. The general performance improvements in this update should help with those problems as well.
How to Get the Fitbit Air Update on Your Device
Google is rolling out this update gradually. That means not everyone will see it at the same time. The company often uses staged rollouts for new firmware, especially on a brand new device. This way, if something goes wrong, only a small group of users is affected. Google can then pause the rollout and fix the issue before it reaches everyone.
If you own a Fitbit Air, here’s what you need to do. Open the Google Health app on your phone. That’s the app that replaced the old Fitbit app after Google’s acquisition. The app should show a notification when the firmware update is available for your tracker. You may need to make sure your Fitbit Air is charged and near your phone to complete the installation.
If you don’t see a notification yet, don’t worry. The gradual rollout could take days or even weeks to reach all users. You can check manually by going into the device settings inside the Google Health app. Look for an option like “Update firmware” or “Check for updates.” But even if it’s not there yet, it will arrive eventually.
Some users on forums have reported that the update downloads quickly and installs in just a few minutes. The Fitbit Air will restart during the process, and you’ll see a confirmation message when it’s done.
What Google Has Said About the Fitbit Air Fixes
Google has been relatively quiet about the specifics of this update. The company hasn’t issued a press release or made a formal announcement. Instead, the update appeared quietly in the Google Health app, and tech blogs like 9to5Google and Android Authority were the first to report on it.
Earlier this year, after the Fitbit Air launched to mixed reviews, Google did acknowledge the automatic workout detection issues. In a statement to Android Authority, a Google spokesperson said the company was “aware of feedback about automatic workout detection and is working on improvements.” That was the first public admission that the feature needed work.
But Google has not explained exactly what caused the problems. Was it a software bug? A sensor calibration issue? An algorithm that needed more training data? Without a detailed changelog, we can only guess. The lack of transparency is frustrating for some users who want to know what went wrong and whether it’s truly fixed.
On the other hand, Google’s approach is fairly standard for firmware updates. Most tech companies don’t publish extensive release notes for wearable firmware. They simply note “bug fixes and performance improvements” and move on. The key is whether users actually see a difference after installing the update.
Broader Context: Google Health App Turmoil and User Revolt
The Fitbit Air’s tracking issues don’t exist in a vacuum. They come at a time when Google is still struggling to win over longtime Fitbit users who were forced to switch to the new Google Health app.
When Google bought Fitbit in 2021, the company promised to keep supporting Fitbit devices. But in 2025, Google began migrating users from the old Fitbit app to the new Google Health app. The transition was messy. Many features that Fitbit fans loved, like detailed sleep tracking, food logging, and social challenges, were missing or changed in the new app.
A report from PhoneArena in June 2026, titled “Google scrambles to fix Google Health launch issues after Fitbit users revolt,” described widespread user backlash. Fitbit users flooded forums with complaints about lost data, confusing interfaces, and missing features. Some threatened to switch to other brands like Garmin or Apple.
The Fitbit Air, as Google’s first wearable under the new Google Health ecosystem, was supposed to be a fresh start. But if the device itself has bugs, it only adds to the frustration. Users who were already unhappy about the app change now have hardware that doesn’t work as advertised.
This firmware update could be seen as a step toward rebuilding trust. If Google can fix the automatic workout detection and other bugs, it shows the company is listening to feedback. But one update won’t erase the broader dissatisfaction with the Google Health app transition. Google still has work to do to convince longtime Fitbit fans that the new direction is worth sticking with.
It’s also worth noting that the gradual rollout of this update is similar to how Google handled firmware updates for the Pixel Watch and older Fitbit devices. The company typically staggers releases to catch problems early. That’s a smart approach, but it also means the most vocal critics may have to wait longer for the fix.
What This Fitbit Air Update Means for Owners Going Forward
If you own a Fitbit Air, this update is good news. It directly addresses the biggest complaint about the device. Automatic workout detection should become more reliable. That means fewer missed runs and fewer false alerts. The tracker should better recognize when you’re actually exercising, whether you’re running, cycling, swimming, or doing yoga.
But it’s important to keep expectations realistic. Firmware updates can improve performance, but they can’t work miracles. If your Fitbit Air’s sensors are physically limited, no software update will make them perfect. The device uses basic optical heart rate monitoring and an accelerometer, which are standard for this price range. It doesn’t have the advanced multi-sensor arrays found in premium smartwatches.
Also, the update is rolling out gradually. If you don’t see it right away, be patient. It will come. And when it does, you may need to give the tracker a few days to recalibrate. Sometimes after a firmware update, the device needs to collect new data to adapt to your movements again.
For people who were on the fence about buying a Fitbit Air, this update removes a major obstacle. The device already offers a slim design, long battery life, and heart rate tracking. If the automatic workout detection now works as promised, the Fitbit Air becomes a much more compelling option in the budget fitness tracker market, competing with devices like the Xiaomi Mi Band and Amazfit Bip.
Google hasn’t announced any more updates for the Fitbit Air, but this first one sets a positive tone. It shows the company is willing to improve the product after launch. That’s important for any new device, especially one that had a rocky start.
So if you’ve been frustrated with your Fitbit Air’s workout tracking, there’s reason to be optimistic. Open your Google Health app. Check for the update. And once it’s installed, go for a run. This time, the tracker might actually know you did it.
