View your Dexcom G5 Mobile data on an Apple Watch

The Dexcom G5 Mobile App now supports Apple Watch and can be used to discreetly view your glucose reading, trend arrow, and trend graph.


To set up:

In order to get started with Dexcom G5 Mobile on your Apple Watch you will need to use the Watch app located on your compatible iPhone. For information on how to set up an app on your Watch please see your Apple Watch user guide.


Please note:

  • Your Apple Watch is compatible with an iPhone 5 or later and the Dexcom G5 Mobile App requires watchOS 2.
  • Your Apple Watch will only communicate with your compatible iPhone, not the Dexcom G5 Transmitter. You will not receive alerts, alarms, and other notifications on the Watch unless it is connected with your compatible iPhone. For example, if you have your Watch on and you go out, but leave your iPhone at home, you will not receive any CGM updates.
  • When you wake up your Apple Watch, it syncs your current CGM data from your compatible iPhone. There may be a brief delay before your Watch app shows current information.
