  • Dexcom G5 Mobile CGM System users can invite up to five followers to remotely monitor their glucose information and receive alert notifications from almost anywhere using the Dexcom Follow App. The Dexcom Follow App is available as a free download through the Google Play store and the Apple® App Store and to the Apple Watch through the Apple Watch Store.

  • If you obtain a new smart device, you will have to reinstall the Follow app. Information on installation can be found in the quick start user’s guide. Once installed, your sharer’s glucose history and trends will show up on your new device.

  • No results will appear when you search for 'Dexcom' in the App Store on your iPad because the Dexcom apps are categorized for iPhone models. Change the search parameters to 'iPhone Only' to see a list of Dexcom apps available for download.

  • We recommend checking the Dexcom compatibility chart before installing a new iOS or Android OS version on your smart device. Dexcom tests all its apps on new OS versions after the OS is released. It may take several days or more to complete testing and, if necessary, update the Dexcom app to be fully compatible with a new OS version.

  • With the Dexcom Follow app, you can follow up to five (5) different Sharers.

  • If you receive an indication from the Dexcom Follow app that push notifications are disabled, Dexcom Share does not have the ability to send you notifications. Go to Notifications in the app settings and find the Dexcom Follow app. Turn the notification center on and set the alert style to Banners or Alerts. Set the sounds to on and set view in lock screen to on.
    LBL-012281 Rev01
  • If you are not receiving notifications, one of the following may be the issue:

    • Ensure your low, urgent low or high notifications are turned on.
    • Check the delay setting for the notifications. If the delay is a value other than 0, you must be below (or above) the threshold for that amount of time before a notification is sent.
    • Your Sharer may not be sharing their glucose.
    • You may have chosen to disable all Dexcom Follow notifications.
    • You may have chosen to turn off notifications.
    • You may have an issue with an internet connection.
    • Dexcom SHARE server may be down.
    LBL-012281 Rev01
  • You will not receive sound notifications on the Dexcom Follow app if the compatible device is set on vibrate.

    LBL-012281 Rev01
  • You should receive notifications to the Dexcom Follow app, even when the app is closed.
