Apple recently launched the iOS 26.4 beta, bringing some exciting updates to the Health app. Two notable features are fresh changes to the Vitals metric and enhanced sleep tracking.
Key Updates in iOS 26.4
First, let’s talk about the Blood Oxygen feature. Earlier this year, Apple had to remove it from the Apple Watch due to a patent dispute with Masimo. They redesigned the feature last August, allowing users to take Blood Oxygen readings on their watches, but the results weren’t shown on the watch itself. Instead, users had to check their iPhones.
Now, with iOS 26.4, Blood Oxygen levels are back on the Vitals graph in the Health app. This means you can track multiple metrics — heart rate, respiratory rate, wrist temperature, Blood Oxygen, and sleep duration — all in one place.
Enhanced Sleep Monitoring
The update also improves sleep tracking. Users can now access a breakdown of their bedtime over the past two weeks, showing average bedtimes and comparisons with last night’s sleep. This new feature can help users identify patterns in their sleep habits, which can be beneficial for overall health.
The Bigger Picture
These updates come at a time when health technology is more important than ever. According to a recent study by the Pew Research Center, nearly 60% of adults in the U.S. track their health data in some form. Features like these in Apple’s Health app cater to this growing interest, making it easier for users to monitor their health in a comprehensive way.
In social media, buzz around the beta update has been palpable, with many users expressing excitement over the return of the Blood Oxygen feature. It highlights how crucial these tools are in managing health, especially in today’s fast-paced world.
