Blood oxygen tracking isn’t coming back to the Apple Watch anytime soon

One of the major selling points of Apple Watches in recent years has been the ability to test users’ blood oxygen levels. Unfortunately, ongoing litigation has prevented this feature from being included in Apple Watches sold in the U.S. since January. Now, it seems unlikely that this situation will change soon.

On Friday, a Delaware jury found that health-monitoring technology company Masimo infringed on some of Apple’s earlier smartwatch patents. As a result, Apple received an award of only $250. However, the same jury ruled that Masimo’s current watches did not infringe on the patents that Apple accused it of copying. Consequently, an injunction remains in effect in the U.S. that prevents the company from offering blood oxygen tracking on new watches sold in the country.

At the beginning of the year, the U.S. International Trade Commission ruled in favor of Masimo, saying Apple’s use of pulse oximeter technology in the Apple Watch violated Masimo’s patents. As such, any Apple Watch sold after January 18, 2024, couldn’t ship with the feature. Soon after, Apple appealed the decision and countersued, alleging Masimo copied Apple Watch features to use in its smartwatches. Since then, it has been unsuccessful in getting the injunction lifted by a court.

Apple’s blood oxygen feature was first available on the Apple Watch Series 6 in 2020. Since then, it has been available on every non-Apple Watch SE model up to the injunction. The all-new Apple Watch Series 10 has the hardware to support blood oxygen tracking. Therefore, whenever a resolution is reached between the two companies, Apple could push out a software update to add those features to watches currently without them.

Blood oxygen tracking measures the percentage of oxygen currently carried by a user’s red blood cells. Numbers below 95% suggest possible health issues, including respiratory conditions, sleep apnea, heart conditions, or more. It’s an incredibly helpful feature, but due to this latest ruling, it will continue to be missing from Apple Watches for the foreseeable future.

I walked a mile with the Apple Watch Series 10 and Pixel Watch 3. Here are the surprising results

The Apple Watch Series 10 is one of my favorite wearables, as it offers the biggest display AND the thinnest build in an Apple Watch to date. Battery life aside, which is much worse than both the Apple Watch Ultra 2 and the Google Pixel Watch 3, it’s the best Apple Watch I’ve ever used.

The Apple Watch comes with a host of features for tracking your fitness, including automatic detection of many different types of workouts, but the tracking of vital signs isn’t the most accurate. The Pixel Watch 3 solves this problem with the best heart rate tracking I’ve tried on a smartwatch, but it doesn’t have as many workout options as the Apple Watch, and automatic detection is inferior as well.

I’ve had the Apple Watch Series 10 for months. Here are 5 things you should know before buying

It's been just about two months since the Apple Watch Series 10 was released, and I've been wearing the smartwatch almost daily ever since. I've used it to track my workouts, monitor my health vitals, manage notifications, and adorn my wrist with the ever-adorable Snoopy watch face.

My opinion of the Apple Watch Series 10 hasn't changed much since I reviewed it in September. I still wholeheartedly recommend the Series 10, and it remains one of the best smartwatches you can buy in 2024.

Like the iPhone did for cell phones, the Apple Watch has changed the market of health and fitness trackers forever. While the iPhone was the biggest product launch under Steve Jobs, the Apple Watch has become Tim Cook’s biggest product launch since taking over after Jobs’ death in 2011.

The original Apple Watch was first announced in September 2014, and since that time, we've had a decade of Apple Watch models for every budget and person. That decade has seen a lot of changes in the Apple Watch, and while the general shape hasn't changed, we've seen many new features, slimmer bezels, and even a new rugged outlook for certain models.
