Fitbit Announces Deal to Bring Glucose Monitoring Data to its Ionic Smartwatch

Fitbit has announced a new partnership with glucose monitoring device company Dexcom that is set to bring diabetes monitoring capabilities to the fitness tracker company's new Ionic smartwatch.

The deal initially means Ionic users will be able to connect a Dexcom device to the Fitbit app and seamlessly transfer up-to-date glucose level data to the smartwatch, making the information more easily accessible on their wrist.

"The collaboration between Dexcom and Fitbit is an important step in providing useful information to people with diabetes that is both convenient and discreet," said Kevin Sayer, President and CEO, Dexcom. "We believe that providing Dexcom CGM data on Fitbit Ionic, and making that experience available to users of both Android and iOS devices, will have a positive impact on the way people manage their diabetes."

There's nothing in the partnership to suggest the Ionic smartwatch will be able to give continuous glucose monitoring readouts on its own when it's released next month – current continuous glucose monitoring systems require a small sensor that's worn under the skin to monitor glucose levels – but Fitbit shares jumped 13 percent on the news, a high for the company since January, when it laid off some of its employees and announced its smartwatch plans.

Dexcom also has a deal with Apple to bring its features to the Apple Watch this year, while owners of Dexcom monitors can already view their glucose data on an Apple Watch – advanced devices by Dexcom include a transmitter, which can display glucose information directly to an iPhone app.

Apple is thought to be working on a non-invasive real-time glucose monitor for a future version of Apple Watch. In April, a CNBC report suggested Apple had a team of biomedical engineers working to develop sensors for non-invasively monitoring blood glucose, with work on the sensors far enough along that the company had started conducting feasibility trials.

Apple CEO Tim Cook was reportedly spotted in May testing a prototype glucose monitor that's connected to his Apple Watch. Cook, who is said to be aiming to understand how his blood sugar is affected by food and exercise, has been seen wearing the device around the Apple Campus.

Apple's $634 Million Apple Watch Patent Bill Just Got Even Bigger

Tuesday October 6, 2026 6:09 am PDT by
Apple's $634 million patent loss to medical technology company Masimo has just gotten even bigger, after a federal judge ordered Apple to pay an additional $184 million in interest on what it owes (via Bloomberg Law). The ruling takes Apple's bill to around $818 million, but that doesn't include any post-judgment interest continuing to accrue until the judgment is paid. Judge James Selna ...

It would be Great if one day smart watches could also accurately detect heart problems before a heart attack occurs.
Long way to go there. Right now optical HRMs (all, not just the AW) cannot detect electrical heart activity. Optical HRM can only detect pulse based on light transmitted though blood. That is why the AW HR data (and other optical based watches) are inferior to those that require a chest strap for data collection. Optically gleaned data:2D, chest straps:3D.

Not Earth-shattering news here, although those who frenzied to buy Fitbit shares didn't appreciate that. The Fitbit will show the data of another device, just as AppleWatch can. Accurate real-time blood glucose monitoring, on the other hand, will be a game changer.
The downside is that if someone were to make non-invasive real time glucose metering accurate and incorporate it natively into, say, the Apple Watch, then every update to WatchOS from the point forward would require FDA approval. It's a bureaucratic nightmare which makes me think they'd want to isolate it in some way (e.g. a band with its own reporting/display mechanism that then uses BT to send to the watch for redundant archival, someone focusing to this area of regulation could weigh in but I believe that lowers the bar then).

It's still invasive, unlike the sensor Apple have been testing.

I'm tired of hearing news like this and Google's AR efforts. Just enough to steal the sheen from Apple but not better, or even as good as Apple products.

I would love Apple to leapfrog others. Completely smash it out of the park like the gap which existed between iPhone 4S and any Blackberry phone in 2011.

2% variance from better monitors isn’t bad at all.
No I don't think you understand the difference between the two technologies. I am not talking about simple pulse. I'm talking about electrical activity, similar to what an EKG does. (Obviously EKGs are medical grade and consumer chest straps are not.) But optical HRMs -- no matter what brand because it's not about brand it's about the technology -- cannot detect electrical activity. There currently is no way to derive heart rate variability (HRV) from an optical sensor -- again regardless of brand.

But yes, if you are training 2% can be the difference from thinking you are in one zone or another -- a zone you don't want to be in. If you don't do heart conditioning then 2% doesn't matter obviously. So it depends what your use it. 2% can be significant and is why people serious about heart conditioning do use a strap.
