Access

One tap from email to questionnaire

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.

  • Magic-link sign-in: no app, no password.
  • My tasks, history and a study switcher for people in more than one study.
  • Every portal login and answer is recorded with a server timestamp.
  • Participants can report an episode between visits and attach photos.

Scheduling

At the visit, or every day in between

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.

  • At specific visits, straight from the schedule matrix.
  • Recurring diaries: daily, weekly or every few days, for example daily from Visit 1 until Visit 15.
  • Completion windows with soft, hard, warning-only or auto-close rules.
  • Completed by the participant, a caregiver, or on a clinic device.

Reminders

Reminders that follow up, then stop

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.

  • A three-step reminder sequence for every task.
  • Quiet hours in each participant's own time zone, plus a daily message cap.
  • Sites can see whether each reminder was sent or bounced.
  • Escalation to the site coordinator when a participant falls behind.

Experience

Built for phones and tablets, in any orientation

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.

  • Tap targets of at least 48 pixels and question text that stays readable.
  • Visual analogue scales with no preset value, so an untouched slider counts as unanswered.
  • Rotate the tablet mid-questionnaire without losing answers.
  • Pinch zoom stays on for participants who need it.

Instruments

Validated questionnaires, with licences tracked

Build validated questionnaires from the wording your licence provides, or draft your own with AI. Mark a questionnaire as licence-required and Capture keeps its licence details with it.

  • Licence number, holder and expiry recorded on the questionnaire.
  • A "copyright approval pending" watermark until the licence is on file, shown to staff only.
  • A warning 30 days before expiry, and the form stops being used for new data once it lapses.

Compliance you can act on

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.

  • Overall and per-site compliance at a glance.
  • At-risk participants and overdue tasks highlighted.
  • Missed questionnaires closed out with a reason, so gaps are explained.
  • A blank ePRO PDF in phone layout for your ethics submission.

FAQ

Questions teams ask before they switch

Something not covered here? Ask us directly.

What is ePRO software?

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.

Do participants need to download an app?

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.

How do reminders work?

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.

Can questionnaires run as daily diaries?

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.

Do you support licensed instruments?

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.

How is ePRO data kept secure?

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.

Can caregivers complete questionnaires?

Yes. Each task can be set to be completed by the participant, a caregiver, or on a clinic device.

Can I try it before buying?

Yes. Build an ePRO in the free sandbox and test it on your own phone. No credit card is needed.
