Does the Fitbit Air support automatic activity detection?
Best answer: Yes, the Google Fitbit Air automatically detects and saves activities in the background. These activities later appear in the Google Health app, where you can confirm, change, or delete them. The Fitbit Air's algorithm will adapt based on how you use the tracker, eventually giving preference to the activity types you track most.
Fitbit Air automatically detects activities in the Google Health appThe Google Fitbit Air is a screenless fitness tracker that monitors your health and activity data in the background. Without a screen onboard, there's no way to manually start tracking a workout directly on the Fitbit Air. Instead, users need to pull out their phone and open the Google Health app to manually track a workout with the Fitbit Air.
The alternative is to use the Fitbit Air's automatic activity detection feature. The fitness tracker monitors health metrics in the background, including your heart rate, steps, and cardio load. These metrics give your Fitbit Air an idea of when you're being physically active. After finishing, you can open the Google Health app to view automatically detected workouts or edit the details.
Google's automatic activity detection might not always get it right, and confirming or modifying the activity in the Google Health app helps improve the results. You can view activities recorded on the same day in the Today tab of the Health app, while older activities appear in the Fitness tab. From there, you can view workout recaps and tap a suggested activity type, or pick other options from the list to confirm.

You can customize activity types and minimum durations for automatically recorded activities in the app. For example, you might not want your 15-minute walk to work to count as an activity, so you could set a 20-minute minimum duration for walks that your Fitbit Air automatically detects.
To improve the accuracy of your Fitbit Air's automatic activity detection, manually start a 10-minute outdoor walking workout using your phone and the Google Health app. Keep your phone on you as you complete the workout. This will calibrate your Fitbit Air, making automatically detected activity data more accurate.
In short, your Fitbit Air can automatically detect activities. However, you may want to confirm or edit activities later in the Google Health app for the best results.
