Google Fit has officially launched a couple of features that have been available for some users. Dark Mode is now fully rolled out to users. This can be enabled/disabled with a toggle in the app’s settings menu. There are also new charts for sleep tracking integrations. The app used to let you pull sleep data from third-party apps before. But now the information is presented in a way that will help you better understand your patterns and trends. So, if you choose to act on it, you can. You can also edit or add sleep history manually if you think it was incorrectly entered. And now iOS users will be able to see the route they ran/walked/biked/exercised as tracked by wearable devices or other apps/services as well as a summary of the workout.
