I let ChatGPT analyze a decade of my Apple Watch data. Then I called my doctor

Like many people who strap on an Apple Watch every day, I’ve long wondered what a decade of that data might reveal about me. So I joined a brief wait list and gave ChatGPT access to the 29 million steps and 6 million heartbeat measurements stored in my Apple Health app. Then I asked the bot to grade my cardiac health.

It gave me an F.

Two things here:

1. The Apple Watch data itself is not accurate
2. And then the bots running the analysis fixate on one or two metrics to provide the analysis.
