For the millions living with diabetes, the distance between a moment of uncertainty and a moment of clarity has quietly narrowed. Dexcom's G7 continuous glucose monitor can now speak directly to an Apple Watch via Bluetooth, removing the iPhone that once stood between a person and their own blood sugar data. It is a small architectural change with a large human consequence — the kind of friction that healthy people never notice, and that people managing chronic illness feel every single day.
Dexcom G7 now syncs directly to Apple Watch, eliminating iPhone requirement
Improved accessibility for 1.7 million+ diabetes patients managing a chronic condition requiring frequent monitoring.
Your watch is now independent. No dead phone, no lost data.

Why does it matter that the iPhone is no longer in the middle of this?
Mimi
Because for someone managing diabetes, you're checking your glucose multiple times a day. If your phone is dead or in another room, you lose access to that information right when you need it most. Now your watch is independent.
Mark
So this is really about freedom of movement?
Mimi
Exactly. You're not tethered to your phone anymore. You can go for a run, leave your phone at home, and still get alerts if your blood sugar drops dangerously low.
Mark
How does this compare to what Samsung or Apple might build into the watch itself?
Mimi
That would be the real breakthrough—a watch that measures glucose without a separate sensor. But that's still in the patent stage. This is the practical solution available today.
Mark
Who benefits most from this change?
Mimi
Anyone with Type 1 diabetes who's already using Dexcom and an Apple Watch. But also people with Type 2 who use continuous monitors. Basically, anyone who needs frequent glucose checks and wants their watch to be truly independent.
Mark
Does this change how people think about managing their condition?
Mimi
It removes a small but real barrier. When the technology gets out of your way, you're more likely to actually use it. That consistency matters for diabetes management.
The Pulse
- Over 1.7 million Dexcom users previously depended on a functioning, nearby iPhone just to see their glucose levels on their wrist — a fragile chain with real consequences for people managing Type 1 diabetes.
- A dead phone, a forgotten device, or a moment across the room could sever the flow of critical health data at exactly the wrong time.
- Dexcom's new Direct to Apple Watch feature collapses the relay into a single Bluetooth connection — monitor to watch, nothing in between.
- Glucose readings now live inside Apple Health alongside sleep, activity, and fitness data, and can be shared directly with healthcare providers and caregivers.
- The feature is live in the US, UK, and Ireland for users running G7 app v2.1+, Apple Watch Series 6+, and iOS 17+, with broader rollout expected later in June.
For the millions living with diabetes, the distance between a moment of uncertainty and a moment of clarity has quietly narrowed. Dexcom's G7 continuous glucose monitor can now speak directly to an Apple Watch via Bluetooth, removing the iPhone that once stood between a person and their own blood sugar data. It is a small architectural change with a large human consequence — the kind of friction that healthy people never notice, and that people managing chronic illness feel every single day.
For the 1.7 million people using Dexcom's continuous glucose monitor, a small but meaningful friction has just disappeared. The G7 device can now transmit blood sugar readings directly to an Apple Watch via Bluetooth — no iPhone required as an intermediary.
Until now, the system worked in stages: the sensor sent readings to an iPhone app first, which then relayed data to the watch. It functioned, but it created a dependency. A dead phone or a forgotten device meant the watch went dark. For someone managing Type 1 diabetes, that gap mattered. The new Direct to Apple Watch feature collapses those steps into one.
People living with Type 1 diabetes have described how invaluable it is to glance at a wrist and see current glucose levels alongside trend arrows — rising, falling, or stable — so they can adjust insulin doses without delay. That information, delivered instantly and without friction, shapes how they move through their entire day.
The feature integrates with Apple Health, placing glucose data alongside sleep, activity, and fitness metrics in a unified dashboard. Caregivers can receive alerts, and users can share data with healthcare providers through compatible health systems.
Prerequisites include G7 app version 2.1 or later, Apple Watch Series 6 or newer on watchOS 10, and an iPhone running iOS 17. The launch covers the US, UK, and Ireland for now. Native blood glucose sensing built into the Apple Watch itself remains on the horizon — Samsung and Apple are both reportedly exploring the territory — but Dexcom's direct sync is the closest thing available today.
For the 1.7 million people worldwide using Dexcom's continuous glucose monitor, a small but meaningful friction has just disappeared. The company announced that its G7 device can now transmit blood sugar readings directly to an Apple Watch via Bluetooth, which means users no longer need to carry their iPhone along to get real-time glucose data on their wrist.
Until now, the system worked in stages. A Dexcom G7 sensor would send readings to an iPhone app first, and only then would that data sync to the Apple Watch version. It was a workaround that functioned well enough, but it created a dependency: if your phone was dead, in another room, or simply forgotten, your watch couldn't show you your glucose levels. For someone managing Type 1 diabetes, that gap mattered. The new Direct to Apple Watch feature collapses those steps into one. The monitor talks straight to the watch. No intermediary. No dead phone problem.
Two people with Type 1 diabetes described to the reporting journalist how they use this setup. Both emphasized that having a glucose complication visible on their watch face—a quick glance at their wrist showing current levels and trend arrows—was invaluable. It lets them see at a glance whether their blood sugar is rising, falling, or stable, and alerts them to urgent changes so they can adjust their insulin dose, whether through a pump or manual injection. That information, delivered instantly and without friction, shapes how they move through their day.
The feature integrates with Apple Health, so glucose readings sit alongside sleep data, activity rings, and cycling metrics in one unified dashboard. Users can share that information with their healthcare providers through compatible health systems, and caregivers can receive alerts and data from someone in their care. For a condition that demands frequent oversight, having all that information in one place and easily shareable is a genuine convenience.
There are prerequisites. Users need the Dexcom G7 app version 2.1 or later, an Apple Watch Series 6 or newer running watchOS 10 or later, and an iPhone with iOS 17 or later. The feature launched in the United States, United Kingdom, and Ireland, with other markets coming later in June. The timing suggests that the Apple Watch Series 10, expected in the fall, won't include native blood glucose monitoring built into the watch itself—though the industry is moving in that direction. Samsung is reportedly making progress on non-invasive blood sugar reading technology, and patents suggest Apple is exploring similar territory. For now, though, Dexcom's direct sync is the closest thing available: the convenience of checking your glucose on your wrist, without needing your phone.
