How to see Dexcom G7 and G6 readings on Apple Watch

Yes. Sweet Dreams shows your Dexcom readings on Apple Watch three ways: as a Live Activity in the Smart Stack, as watch-face complications, and in the Sweet Dreams watch app. You connect with your normal Dexcom account (not Dexcom Follow).

Step 1: Connect Dexcom to Sweet Dreams

Already have a follower in Dexcom Follow? Skip to the last step.

1. Open the Dexcom app and tap the Share icon to turn on Dexcom Share.
2. Invite at least one follower. Your own email address works. Dexcom doesn't send readings to its servers unless someone follows you, so this step is required even if you only want to see your own data.
3. In the follower settings, make sure the follower can see your trend graph.
4. Accept the invitation in the Dexcom Follow app. Download it first if you don't have it.
5. In Sweet Dreams, choose Dexcom and sign in with the wearer's Dexcom account, not the Dexcom Follow account.

Step 2: Set up Apple Watch

1. Install Sweet Dreams on your iPhone and sign in. The watch app installs with it.
2. Live Activity (recommended): start a Live Activity on your iPhone. On watchOS 11 or later it appears in the Smart Stack; scroll down on any watch face to see it.
3. Complications: long-press your watch face, tap Edit, and add a Sweet Dreams complication to any slot.
4. Watch app: open Sweet Dreams on the watch for the latest reading, a timer and a graph. To keep it on screen for up to an hour, open the Watch app on your iPhone, go to General → Return to Clock → Sweet Dreams, turn on Custom and choose After 1 hour.

Good to know for Dexcom

• The Live Activity refreshes far more often than complications and is the option we recommend.
• Complications fit in with the rest of your watch face but Apple limits how often they refresh (we see every 15–20 minutes), so always check the timestamp on them.
• In the watch app the background colour changes with your thresholds, which you set under Notifications in Settings on your iPhone.

Why not just use a widget?

Widgets and watch complications are refreshed on a budget Apple sets, which we've seen work out to every 15–20 minutes, in every app. That's why glucose widgets, including those in official CGM apps, can show an old reading. A Live Activity is refreshed every few minutes instead.

Free on the App Store for iPhone, Apple Watch, iPad and Apple silicon Macs.
