The Apple Watch needs a better Siri more than the iPhone right now

Apple's developer conference could mark a turning point: the next Siri is expected to run on Google's Gemini, a notable shift for a company that long kept hardware and software tightly closed. The move has obvious implications for phones, but it may matter even more for the Apple Watch and the company's health platform.

My testing of Google's AI Health Coach shows how useful a chatbot can be when it links to sleep, exercise and stress data to provide personalized answers and recommendations. Apple already collects similar data from the Apple Watch, so a substantial software upgrade — not a separate tracker — would do more to advance its health suite than hardware alone.

A redesigned Health app could host a health chatbot that connects information across Health, Journal and the Fitness app, logging details automatically. For example, a mood entry in Journal could be tied to sleep or workout metrics; building on Apple's Sleep Score, daily summaries and bedtime recommendations could become more actionable.
