Earlier this month, ChatGPT Health, which integrates with Apple Health, analyzed Geoffrey A. Fowler’s Apple Watch data — about 29 million steps and 6 million heartbeat measurements — and produced inconsistent cardiac health grades. The Washington Post found the tool relied on estimated VO2 max, ignored sensor-driven resting heart rate shifts, and repeatedly forgot demographic and lab details, producing grades that varied from F to B.
Key Points
- 1Reports show ChatGPT Health gave inconsistent cardiac grades using Apple Watch data (F to B).
- 2Relied on estimated VO2 max and ignored sensor-driven heart-rate changes, causing misleading interpretations.
- 3Prompts caution for clinicians and users; limits health decision-making and necessitates validation.
Scoring Rationale
Moderate relevance and actionable insight from a reputable outlet, limited by single-source testing and lack of systematic validation.
