An Apple Watch app is coming for people with diabetes

Medical device maker Dexcom has been showing off iPhone and Apple Watch integration for its implantable diabetes glucose monitors for the past few weeks. The app will display glucose readings on iOS devices and should be ready when Apple Watch is launched in April, according to the Wall Street Journal.

The Dexcom Apple Watch app, medical device experts say, is made possible by recent Food and Drug Administration policy changes that suggest the federal agency will only regulate medical hardware, and not the apps that connect it to consumer platforms like iOS and Android. The exact scenario of glucose monitoring for people with diabetes was discussed when Apple quietly met with FDA officials to discuss the possibility of Apple Watch triggering federal regulation.

People with diabetes and their loved ones want the kind of features that Dexcom’s iOS app promises. In fact, Dexcom’s app was preceded by NightScout, a open-source, not-for-profit, and unregulated set of tools created as a labor of love by software engineers around the world. NightScout takes readings from Dexcom glucose monitors, uploads them to the internet, and can display them on devices like the Pebble smartwatch.

Dexcom’s demos have only shown its Apple Watch app displaying glucose readings. There might be other features included, including alarms and calibration, but those haven’t been revealed yet.

The opportunity for Apple and device makers like Dexcom in mobile health is huge. Credit Suisse estimates there are 400 million people worldwide with Type II diabetes, with associated costs totaling up to $376 billion per year. If hospitals and patients are already spending thousands of dollars a year managing the condition, and a $350 Apple Watch and $650 iPhone can make their lives markedly better, then it becomes an easy purchase. If doctors start choosing devices based on whether they work with iOS, that could prompt other manufacturers to support iOS and HealthKit, which would lead to more health-conscious consumers choosing Apple.

Dexcom’s glucose monitors come in the form of a wearable patch called a continuous glucose monitor. Currently, diabetes patients need to carry around a pager-like device to read glucose levels, but the new apps will allow users to ditch the glucose sensor reader for the smartphone they already likely carry.



Has anybody started using this app with the new apple watch or on their smart phone?


excited about new of app for iPhone my grandson is type 1 this would make my daughter and son in law rest easier, and grandparents

Excited for the technology, but frustrated as a Type1 diabetic that there’s a paragraph about Type2 diabetes within the article. CGMs aren’t for T2s, insurance won’t even consider them. This technology affects and improves loves and outcomes almost exclusively for T1s, and this misinformation continues to blur the lines about the two very different diseases. Would love to see an update with information pertaining to T1s.

Sorry, I’m not a medical expert, I write about mobile technology and Apple. I understand Type II is significantly different condition, those were just the stats I had on hand.


Hey Kif, did you hear that Microsoft has sold over 200M Windows 8 Licenses? I know that Microsoft is significantly different than Apple, those were just the stats I had on hand.


As a type 1 diabetic, I dream of an app like this and after 25 years as a diabetic this would, be the most significant and life changing innovation in my lifetime, BUT…
Having had the opportunity to use a Dexcom CGM for a week last year I looked into getting one full time, only to learn that it’d cost something like AUD$3-5k a year for the transmitters alone — which is beyond reach for most people. A shame as it’s wonderful technology. For the first time since we were married my wife and I could sleep without worrying about me falling into a hypo. Fingers crossed for the day this becomes affordable to more diabetics.


This mentions Type 2 diabetes as the target audience. Type 1 diabetics are the target audience for CGM because their block sugar changes so much more quickly.


Mike is correct. CGMs do not replace traditional glucose monitors, so you’d need both.


Great for people that can afford it. Im pretty sure United Healthcare or any other insurance is not going to help defer the cost.


A glucose monitor that can display it’s readings on an iPhone app does NOT mean you can stop testing your blood sugar levels with a glucose meter. A glucose monitor is not as accurate as using test strips and is just a way to allow you track your blood sugar levels over a longer period of time instead of just before meals, wake up or go to bed.

More accurately, ten diabetes tracking apps are coming for the Apple Watch.
