Your health data,
with its sources intact.

HealthCollector is a private iPhone app for reviewing activity, sleep and recovery information from connected wearables. It brings authorized Fitbit data and supported Apple Health records into a privately operated backend.

A separate research dashboard compares imported WHOOP and Withings exports with Fitbit measurements. Comparisons describe agreement between devices; they do not establish medical accuracy.

A private installation

HealthCollector currently serves its owner’s personal installation. It has no public sign-up. Connecting Fitbit requires a separate Google authorization. Optional AI-assisted analysis requires separate consent inside the app.
