Bring your Health data
On your iPhone, open Health, tap your profile picture, and choose Export All Health Data. Unzip what it gives you and hand this page the export.xml inside.
The file is read in your browser. Nothing is uploaded, and nothing is kept when you close the tab.
Non-diagnostic by design. Nothing here detects, treats or diagnoses anything, and nothing measures hormones. It is a heart-rate-versus-movement pattern, and that is all it claims to be.
Reads an Apple Health export rather than syncing HealthKit, so it needs an iPhone to have produced the data — there is nothing to import from an Android phone yet.
