They want your blood
A review of Death Clock, an app that estimates how long users may live, highlights the growing use of blood tests by health technology companies. The app links blood panels and other health recommendations to the promise of a longer life, raising questions about whether the personal data users provide is matched by useful, reliable benefits.
The writer says Death Clock predicted she would live to 97, or to 114 if she followed its full set of suggestions. Its $69 annual subscription includes a blood panel, with additional tests and devices recommended at extra cost; the app also suggested screening, scans and supplements. The article notes that Oura, Whoop, Google and Apple are also moving into blood testing through partnerships, while Death Clock’s founder argues that blood data can help people understand their health.
