The Apple Watch 6 could be capable of detecting blood oxygen levels

The Apple Watch may soon be able to measure blood oxygen levels. Based on snippets of code inside iOS 14 acquired exclusively by 9to5Mac, Apple is developing two new health features for the next version of its smartwatch, likely to be called Apple Watch 6. At the moment it’s unclear whether these will be limited to the next-generation Apple Watch or also roll out to existing models through a software update.

Apple is said to be designing a new health notification that will go out whenever the watch detects the user’s blood oxygen levels have fallen below an alarming threshold. This will function similarly to the Apple Watch’s existing irregular heart rate alerts and nudge the user to consult a doctor instead of revealing anything conclusive.

A number of critical health conditions are associated with this health metric. When your blood oxygen saturation slips past the normal range, it can cause respiratory troubles and eventually lead to a cardiac arrest. As Apple continues to position the Apple Watch as more of an accessible health tool rather than a smartphone companion, the addition of blood oxygen detection will prove handy and compliment the rest of the features.

The ability to detect blood oxygen saturation is growing increasingly common among smartwatches. Fitbit brought it in January earlier this year to a handful of its products. French wearable maker, Withings’ latest, the ScanWatch can also record your blood oxygen levels.

All of these existing implementations rely on a set of special red and infrared sensors to measure blood oxygen levels. Therefore, it’s possible Apple’s new feature will be exclusive to the Watch Series 6. Although as per 9to5Mac, there is a chance it may come newer Apple Watch models with watchOS 7.

In addition to that, the Apple Watch’s electrocardiogram function may be all set for an upgrade. The Cupertino, California-based company is reportedly testing a better ECG app for the Watch Series 4 and Series 5 that will be capable of delivering more accurate results for heart rates between 100 and 120 beats per minute instead of producing inconclusive readings.

Apple is also rumored to be working on a sleep-tracking feature for the Apple Watch. The new feature, which was first detailed last year, will keep tabs on the user’s quality of sleep through a range of sensors and inputs such as their movement at night, heart rate, noises, and more.

I used a smart blood pressure monitor for the first time — and it blew me away
The Withings BPM Connect blood pressure monitor with the Health Mate app.

After getting a health check in April, I was told my blood pressure was slightly elevated and that I should get a monitor and keep a record of results for the next four weeks — after which time it would be assessed again and decided if I needed medication to control it. Not the best thing to hear, but not the worst either. Time to get the right equipment and get started.

I had access to a normal blood pressure cuff, but that was a bit, well, boring. Plus, the manual process of logging results and keeping records put me off. I'm used to health tech like the Apple Watch and the Oura Ring, where an app collates and presents the data, and everything is laid out for me. Could consumer tech come to my aid here and give my doctor all the required information after the month was up?
Step forward, Withings

Leaked renders of the Samsung Galaxy Watch 6 Classic.

Samsung’s slate of next-gen hardware has started popping up in leaks, once again, weeks ahead of their launch. This time around, @OnLeaks (via MySmartPrice) has shared renders supposedly depicting the Galaxy Watch 6 Classic, the more upmarket trim of the vanilla Galaxy Watch 6.

Now, Samsung is once again playing a minimalist game with the design, retaining the signature round dial and the curved hook aesthetics of its previous smartwatches. However, the biggest change in 2023 will be the return of the rotating bezel on the Galaxy Watch 6 Classic.

Posted to the subreddits r/AppleWatch and r/watchOS, users are reporting that the update has added a noticeable green/gray tint to their screens that changes the colors of the display and makes the usually crisp OLED screen look washed out. You can see what it looks like in the photos below.
