Yes, you can silence notifications and/or alarmrs from the mySugr app temporarily or set your mobile device to vibrate only.

You can disable Critical Alerts (iOS) or Override Do Not Disturb (Android) for the mySugr app. However, when you disable these settings, if you put your mobile device in Do Not Disturb or Focus mode, all app notifications are silenced temporarily while your phone is in that mode. 

If the Critical Alerts or Override Do Not Disturb settings are enabled for the app, the app will override these modes and make sounds for each notification even if your phone is set to vibrate only or Do Not Disturb or Focus mode.

The app prompts you to enable these settings during the initial setup, but you can also access them at any time. In addition, some alarms and notifications can be turned off entirely from the More menu. Beware that this will turn off the notification entirely and not just silence it. It will stay off until you turn it on again from the menu.

Make sure that notifications, alarms, and Override Do Not Disturb (Android) or Critical Alerts (iOS) are turned on in mySugr Glucose Insights. Otherwise, you may miss glucose alarms or important safety information. You can also add the mySugr app to the list of allowed app notifications. For more information on how to do so, see the User’s Manual of your mobile device.
