Fitbit’s AI health coach will soon be able to read your medical records

Google announced that Fitbit's AI health coach will soon allow US users to link their medical records to the app, enabling more personalized health advice based on lab results, medications, and visit history alongside wearable data. Google stressed the data won't be used for ads or to diagnose conditions, and users retain control over sharing and deletion. Fitbit's sleep tracking is also getting a 15% accuracy improvement in what Google calls its most significant update yet.
