Samsung’s AI upgrade turns raw health data into daily advice

The intersection of personal health and wearable technology is about to get a major brain upgrade. Samsung has announced a sweeping update to its Health app, set to roll out on June 8, that aims to transform the deluge of raw biometric data on your wrist into clear, actionable advice for daily living. The overhaul serves as a software preview for what users can expect from the company's next generation of wearables, presumably the highly anticipated Galaxy Watch 9 and Ultra 2 slated for a July reveal.

At the center of this update is generative artificial intelligence, which Samsung is leveraging to bridge the gap between complex health metrics and everyday understanding. A prime example is the new Vitals feature, an evolution of the old app's Energy Score. Instead of just throwing charts at you, the AI quietly analyzes your overnight heart rate, respiratory patterns, skin temperature, and blood oxygen levels, measuring them against your personal resting baseline. If the system detects an unusual spike or dip, it skips the medical jargon and simply notifies you that you might be fighting off a bug or just desperately need a rest day.

The app is also rethinking how it tracks cardiovascular fitness by introducing the Heart Health Score. This feature replaces the older, more clinical "vascular load" metric, which measured how hard the heart works to pump blood. The new score blends those cardiovascular data points with sleep quality, daily stress levels, activity history, and body composition data to hand you a literal scorecard for your heart. Rather than leaving you to figure out what that score means, the app steps in with tangible lifestyle tips, like adjusting your daily step goals or adding potassium-rich foods like bananas to your grocery list.

For fitness enthusiasts, the updates bring a more tailored approach to training. A new tool called Daily Cardio Load actively calculates optimal workout targets and necessary recovery windows in real time, shifting based on your current physical profile and metrics. That is paired with the new Fitness Index, which takes your daily movement and key metrics like VO2 max—the maximum amount of oxygen your body can utilize during intense exercise—and benchmarks them against your peers. The app then uses that comparative data to spin up personalized goals, helping you pinpoint exactly whether you need to log more miles for endurance or hit the weights for strength.

While these AI advancements will technically function across Samsung's broader ecosystem of mobile phones and connected devices, the tech giant notes that the features are built to be fully realized on its upcoming hardware. With an Unpacked event expected this July, the updated app offers a compelling glimpse into how Samsung intends to make its next flagship watches less like passive data trackers and more like proactive health coaches.
