If you have the fitness app "Google Fit" installed on your Android phone, you will hear every time a new notification is displayed a notification sound. This notification sound from Google Fit maybe bothers you with time, but we will tell you here now in more detail how you can disable it. Please proceed as follows:
Open the app Google Fit on your Android phone.
If you are in the index, then tap in the top right corner on the three-point symbol. In the pop-up menu, tap "Settings". Scroll all the way down. Now you see the section "Notifications". Disable the "Notification Sounds" by the controller.
From now on you will hear no sound notifications by Google fit on your Android phone.
