Dexcom connects G7 CGM directly to Apple Watch in US

Dive Brief:

Dive Insight:

Apple Watch users could display glucose data from older Dexcom CGMs on their wrists but there were limitations. The wearable took data from the user’s iPhone, rather than directly from the CGM, and Apple’s limit on the number of times third-party apps can refresh the watch meant the screen did not always show the latest information. 

Following the update, Dexcom G7 can connect to a phone, pump and watch via Bluetooth at the same time. The change allows Apple Watch to pull data directly from Dexcom G7 in real-time. 

Dexcom said in March that the Food and Drug Administration had cleared the direct-to-watch feature. Users in the U.K. and Ireland could access the feature when Dexcom held its first-quarter earnings call in April. 

“Our users are going to be able to … have an incredibly discrete experience with CGM on an Apple Watch only, and that will include all of our share-follow system as well,” Sayer said on the call. “Imagine a parent who wants to send their kid to school without a phone. They will be able to do everything on a watch that they used to be able to do on their phone.”

The feature is now available to users in the U.S., U.K. and Ireland. Dexcom plans to launch in additional markets later in June. 

Adding the direct-to-watch feature sets Dexcom G7 apart from Apple’s Freestyle Libre CGM devices. The App Store lists third-party software for displaying Freestyle Libre data in Apple Watch, but Abbott is yet to create a direct connection between its CGM and the wearable.

Both companies now have FDA clearances for over-the-counter CGMs.
