How it works

From setup to datain minutes

Three simple steps to go from sign-up to analysis-ready data.

Step 01

Create or join a study

Researchers spin up a study and share a code. Participants join in seconds — no account hoops.

Step 02

Connect a wearable

Participants authorize Fitbit or Apple Health via OAuth. StudySync ingests securely from there.

Step 03

Monitor & export

Track enrollment and sync health in real time, then export analysis-ready datasets.
