The FDA just approved an Apple Watch app to track Parkinson’s disease

The U.S. Food and Drug Administration (FDA) has given the green light to an Apple Watch app to monitor Parkinson’s disease, developed by San Francisco-based startup Rune Labs. As reported by Reuters, the Apple Watch’s pre-existing sensors can already detect falls, tremors, and other movement disorders consistent with symptoms of Parkinson’s. But Rune Labs has taken things a step further with its app, gathering individual data on the symptoms patients experience so that it can be shared with doctors to determine the best course of treatment.

Brian Pepin, CEO of Rune Labs, said that the data Apple Watch gathers through its Parkinson’s monitoring app will be combined with data from other sources, like brain implants. He also added that the app uses Rune Labs’ StrivePD software to send doctors continuous streams of data to give more context to movement patterns. This provides more data than doctors would get from observing a patient coming in for a short clinical visit, as symptoms of Parkinson’s disease change over time.

“When you think about the process of getting someone to their optimal therapy or combination of drugs or devices, or even whether or not a patient might be a good fit for a certain clinical trial, it’s a very hard decision to make when you only have a little context,” Pepin said.

Developers have been testing the Apple Watch’s monitoring of Parkinson’s disease ever since Apple introduced its ResearchKit framework in 2015. Originally, this allowed the Apple Watch to track users’ walking gait by prompting them to walk 20 steps every which way. Three years later, Apple updated ResearchKit with the Movement Disorder API, which can detect two common symptoms of Parkinson’s: tremors and dyskinesia, a side-effect of Parkinson’s medications that causes fidgeting and swaying motions.

The Parkinson’s monitoring app is the second Apple Watch software to receive FDA clearance after the agency cleared AFib History for use in watchOS 9 following its WWDC presentation last week. This feature tells users diagnosed with atrial fibrillation how frequently their heart rhythm shows signs of AFib, which, if left untreated, can cause a stroke and other cardiovascular complications.

5 features I want in the Apple Watch Ultra 3
The Apple Watch Ultra 2 laying on the ground, showing the Modular Ultra watch face.

When Apple debuted the Apple Watch Ultra in 2022, it was one of the company’s best new products that year. After years of rumors and speculation, it finally arrived and exceeded expectations with the best battery life for an Apple Watch, incredibly useful new features like the Action button, a super-bright and large display, and more.

A year later, Apple launched the Apple Watch Ultra 2. Though still a great smartwatch, it felt a bit more like an iterative upgrade than something big. It had a new S9 processor that allowed for the Double Tap gesture and localized Siri requests, and an even brighter display. But otherwise, it looked identical to the original Apple Watch Ultra.

Apple Watch X: The 9 biggest things I want to see
watchOS 10 running on an Apple Watch Ultra.

The original Apple Watch was announced in September 2014, with Apple's first smartwatch released in April 2015. Lat year, we got the Apple Watch Series 9 and Apple Watch Ultra 2, both of which were relatively iterative upgrades. Now, we should focus on what Apple could be doing for the 10th anniversary of the Apple Watch, similar to what the company did with the 10th anniversary of the iPhone, which gave us the iPhone X.

Rumors suggest that this anniversary smartwatch could be called the “Apple Watch X," and we could see it later this year or, more likely, in 2025.

You’ll be waiting a while longer for blood glucose tracking on smartwatches
Post-walk fitness data on the Apple Watch Series 9.

Apple and Samsung — the two titans of the smartwatch industry — are chasing a new feature that would allow a smartwatch to measure the glucose levels in your blood. But the U.S. Food and Drug Administration (FDA)  is already concerned about misleading marketing tactics, even though the feature is yet to appear on a commercially available smartwatch from a well-known brand.
“The FDA has not authorized, cleared, or approved any smartwatch or smart ring that is intended to measure or estimate blood glucose values on its own,” says the regulatory agency. As such, the agency has asked users that they should refrain from buying or using smartwatches or rings that claim to measure the sugar levels in the bloodstream. 
Right now, there are medical-grade devices out there that can measure blood glucose levels, but most of them rely on an invasive method where a small puncture is required to draw out a blood sample and then analyze it. Noninvasive blood glucose monitoring has remained elusive so far, especially in a miniaturized form that is suitable for smartwatches.

In 2020, Samsung announced that it had developed a noninvasive method for blood glucose level measurement in partnership with the Massachusetts Institute of Technology (MIT). Samsung didn’t specify whether the tech would make its way to a smartwatch, but multiple reports claimed that Samsung is exploring the tech for its smartwatches. 
Apple, on the other hand, is also said to be working toward the same goal. Rumors suggest that noninvasive blood glucose level analysis could arrive as a marquee new addition for the t10th-generation Apple Watch slated to hit the shelves later this year. 
Assuming the tech eventually makes it to the market later this year, it would start a mad race where every player would want to advertise that health facility for their own product. And that would mean misleading marketing claims, which is already a worrisome reality. It seems the FDA has already braced for the onslaught and has, therefore, made it clear that it hasn’t certified any such tech -- from Apple or any other consumer electronics brand whatsoever.
