The Freestyle LibreLink apps include several optional alarms you can choose to disable depending on the LibreLink app settings and your intended use of CGM monitoring.

The majority of Veri users choose to toggle 'off' all alarms since they are not necessary for individuals tracking glucose for wellness purposes.

Freestyle Libre 2 & Freestyle Libre 3 Alarms

To locate the alarm settings in your LibreLink app:

  1. Click on the settings menu in the top left corner

  2. Tap Alarms

  3. Toggle 'on' or 'off' the various alarms based on your preference

Here, you’ll see options for:

  • Low glucose alarm

  • High glucose alarm

  • Signal loss alarm

  • (Urgent low glucose alarm)

If you keep the low or high glucose alarm ‘on’, you will need to set the glucose value parameters for when you'd like the alarm to notify you. In doing this, you can select the alarm tone that plays and decide whether you'd like the app to notify you even if your phone is muted or set to Do Not Disturb.

Enabling the Signal loss alarm will result in an alarm sounding when Bluetooth is turned off or if your phone is too far from your sensor to receive a reading. Essentially, if your phone cannot communicate with the sensor, you will be notified. This can be quite disruptive, so we generally suggest toggling off this alarm.

Freestyle Libre3 only

The Freestyle Libre 3 has one additional alarm - the Urgent low glucose alarm; it is not possible to turn this alarm off in the United States.

Low readings overnight are common due to added pressure from sleeping on the sensor (rather than genuine low glucose concern; this is known as a “compression low”). If you would like to disable this alarm to avoid being woken up in the night, we recommend temporarily disabling Bluetooth on your phone when you go to sleep.

Since the Freestyle Libre 3 sensor can store up to 14 days' worth of glucose data at a time, disabling Bluetooth in the overnight hours should not result in data loss. Simply enable Bluetooth again when you wake up and your overnight glucose readings will populate in the Libre3 app.

Freestyle Libre 1 (aka. 14-day)

Alarms are not automatically enabled on the associated Freestyle Libre 1 or Libre 14-day apps, so there is no need to worry about disabling alarms for these devices.

* Please note that the Veri app also has optional alarms and notifications with more information available in this guide.
