How to activate alarm notifications on a smartphone
To receive optional glucose alarms on your smartphone, you need to make sure you have notifications enabled for the app. If you didn't enable all notifications and permissions during app set up, how you do it now depends on whether which app you're using and your phone's operating system.
On an iPhone
-
Enable Bluetooth and allow the App to access Bluetooth.
-
Allow Notifications for the App. Turn on Lock Screen and Banner alerts, Notification sounds, and general phone sounds or vibration. Be sure not to turn on any features or modify phone settings that may interrupt the presentation of notifications.
If you use Do Not Disturb mode on your phone:
Turn off Do Not Disturb mode or select to turn on Override Do Not Disturb in your alarm settings. Do this if you want the alarm to always play a sound and appear on the lock screen even if your phone is muted or Do Not Disturb is on.
Note: You must accept the app’s permission request for Critical Alerts to use this feature. You can also enable the Critical Alerts setting directly from the app’s notification settings.
On an Android device
-
Enable Bluetooth and allow Nearby Devices permission for the App (Nearby Devices permission is required for Android 12 and above).
-
Allow Notifications for the App. Turn on Lock Screen notifications, Notification sounds, Channel notifications, Sound and Pop-up notifications, and general phone sounds or vibration. Make sure not to turn on any features or modify phone settings that may interrupt the presentation of notifications.
-
Turn off Do Not Disturb mode or manage the settings for your alarms to override Do Not Disturb. Override Do Not Disturb functionality depends on the phone model and Android operating system version you are using.
-
Allow Alarms & Reminders permission for the App. This permission is required for Android 12 and above.
-
Turn off Battery Optimisation for the App to allow the App to run in the background and ensure that you receive alarms, even when your phone has low battery.
-
You may need to add the App to the list of apps that will not be put to sleep.
