How it works
Site staff send a portal link from the subject page, or participants request one themselves with their email. The link signs them in once, then the portal lists every task that is due.

The difference
Yes. Capture's participant portal runs in the browser. Participants open a secure link on their phone or tablet, with nothing to install.
Sign-in links are single-use, sessions expire after inactivity, sites can revoke access, and every login and answer is recorded in the audit trail with a server timestamp.
Any modern phone or tablet browser, plus clinic devices. The layout adapts to phones and to iPads in portrait and landscape.
Your study team, in a visual editor. AI can draft a questionnaire from a description or a file, including an instrument you hold a licence for.
Site staff send it from the subject page, or participants request a new link with their email address. Studies can also publish a landing page with a QR code.
Yes. Reminders go by email when a task is due, the next day and before the window closes, and they respect quiet hours in the participant's time zone.
Yes. The participant portal and landing pages can carry your study's branding.
There is no app to build or approve, so launch depends only on building and approving your questionnaires. You can try it today in the free sandbox.
