Top FAQs

• Can I view my Dexcom G6 CGM data on an Apple Watch?

  Yes, you can check your CGM information on your wrist! The Dexcom G6 app supports Apple Watch and can be used to discreetly view your glucose reading, trend arrow, and trend graph. Use the digital crown to scroll the trend graph view between 1, 3, or 6 hours of data. 

  

  You can also view your number and arrow as a complication on your watch face. You can choose from 5 complication styles depending on your preferred watch face.

  

  To set up Dexcom G6 on your Apple Watch you’ll need to use the Watch app located on your compatible iPhone. To add complications, use the Watch app to choose the watch face and complication style that you want. If you would like the color of your Dexcom complication to reflect your glucose status, choose the multicolor option for the watch face.

  See your Apple Watch instructions for more detail on setting up an app on the watch. 

  When you wake your Apple Watch, it syncs your current CGM data from your compatible iPhone. There may be a brief delay before your watch app or complication shows current information. Place the Dexcom G6 app in the Dock and turn on background app refresh for best performance.

  Your Apple Watch will only communicate with your compatible iPhone, not the Dexcom G6 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.

  Compatibility:
  Dexcom G6 App v1.4 and Apple Watch running watchOS 3 or later required. US only.

• Is the Dexcom G6 App compatible with Siri?

  With the latest G6 app update you can now ask Siri to recite your Dexcom glucose readings out loud and display your graph directly on the lock screen.

  This feature is only compatible with iOS devices using iOS 12 and above and supported Apple Watches and watchOS. Click here to view our compatible smart devices.

  Siri activation:

  To enable please follow these steps:

  • Make sure that you’re connected to the internet. 
  • Click on “Siri Shortcuts” from G6 App Settings 
  • Tap the “Set up Siri Shortcuts” button 
  • A setup wizard will launch to guide you through setting up this feature. If you haven’t yet enabled Siri on your iOS device, you will be guided to do that first. 
  • Record the phrase you would like to use when you want to activate the task. We recommend “What’s my glucose?”. Click the red button to activate recording and again to stop recording. 
  • Confirm – After recording you will see the transcribed text of the recorded phrase. Here you have the option to edit this phrase. Click “Done” to save.

   

  Siri response:

  When a reading is available you can activate Siri by using the recorded phrase (see recording instructions above) and one of the following standard phrases will be read:

  "Dexcom G6 says..." 

  • you're 110 and steady. 
  • you're 110 and slowly rising. 
  • you're 110 and slowly falling. 
  • you're 110 and rising. 
  • you're 110 and falling. 
  • you're 110 and rapidly rising. 
  • you're 110 and rapidly falling

   

  If a glucose reading is not available, you will be instructed to check the app for more information.

  This is an optional feature that must be set up by the user via a set up wizard in the G6 app. To use this feature, you MUST have Siri enabled on your phone and you must be connected to the internet. Siri responds only to your voice and the phrase you choose.

• How do I set up the Dexcom G6 with my phone?

  The Dexcom G6 app has to be downloaded and is different from the Dexcom G5 Mobile app. (Please note: The G6 system will not work with the G5 Mobile app.) It is available for free from the Apple App or Google Play stores. The app is named “Dexcom G6”.

• What devices and software are compatible with the Dexcom CGM apps?

  ^{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.}
