Access
Participants receive a secure sign-in link by email. It opens their portal straight away, lists what is due and walks them through one question per screen. Sessions time out on their own, and sites can revoke access on a lost or shared device.

Scheduling
Each questionnaire runs one of two ways. Tie it to the visits you tick in the schedule, or run it as a recurring diary between two visits with its own time window.
Reminders
Capture reminds participants when a task is due, the day after, and once more before the window closes. It stops the moment the task is done and never messages during quiet hours in the participant's own time zone.

Experience
Every questionnaire is laid out for touch. Large tap rows, readable type and a Next button that stays above the keyboard make it easy for any participant, on a phone or an iPad in the clinic.

See who is falling behind before it becomes missing data. The dashboard tracks compliance by study, country and site, and flags at-risk participants and overdue tasks.
At-risk participants
ePRO (electronic patient-reported outcomes) software lets trial participants answer questionnaires and diaries electronically instead of on paper. Answers are timestamped, checked and available to the study team straight away.
No. Participants open a secure link in the browser on their own phone or tablet. There is no app to install and no password to remember.
Each task gets up to three reminders: when it is due, the next day, and a final notice before the window closes. Reminders stop once the task is done and respect quiet hours in the participant's own time zone.
Yes. A questionnaire can run at specific visits or as a recurring diary between two visits, daily, weekly or every few days, with its own completion window.
Yes. Build the questionnaire from the wording your licence provides, mark it as licence-required and record the licence number and expiry. Staff see a watermark until those are recorded, and Capture blocks new use once the recorded licence expires. Capture does not supply instruments or licences.
Sign-in links use single-use tokens, sessions time out after inactivity, sites can revoke access, and every login and answer is recorded in the audit trail.
Yes. Each task can be set to be completed by the participant, a caregiver, or on a clinic device.
Yes. Build an ePRO in the free sandbox and test it on your own phone. No credit card is needed.
