Apple VP Sumbul Desai Talks Overhauling the Health App [VIDEO]

In a recent interview with Wall Street Journal tech columnist Nicole Nguyen, Apple Vice-President of Health Dr. Sumbul Desai detailed Apple is overhauling how its devices collect, interpret, and present health data.

Desai acknowledged that while the Apple Health ecosystem excels at secure, end-to-end encrypted data collection, it has long fallen short on giving users clear guidance on what to actually do with those numbers. To fend off rising competition from dedicated health-tracking wearables like Whoop and Oura, Apple is rolling out an AI-infused redesign of its Health app alongside key algorithm updates for the Apple Watch.

The Apple Health app was not originally created as an interactive daily dashboard. Instead, it was built as a secure background repository for storing healthcare records and syncing developer data. Over the years, Apple added trend lines and historical charts, but the app often felt like a static wall of numbers rather than a helpful guide.

Apple’s redesign aims to turn the Health app into a daily, proactive coach. A revamped Today tab presents a unified dashboard featuring bite-sized daily insights and proactive recommendations. Rather than simply alerting a runner that their VO2  max or cardio fitness has dropped, the updated app offers specific advice on adjusting workout intensity levels to help restore cardiovascular health.

Apple is also doubling down on longevity metrics with features like “Health Age.” By evaluating core habits, including movement, resting heart rate, VO2 max, lab results, and sleep quality, the metric is designed to help users focus on overall life quality and long-term health habits rather than chronological age.

Alongside software changes, Apple is deploying algorithm updates to fix long-standing false-positive glitches on the Apple Watch. You can watch Desai’s full interview embedded below.
