Datacubed focuses on participant engagement in eCOA. Capture protects compliance with completion windows, a three-step reminder ladder and at-risk alerts, with participant data in the same study as site data.

The comparison
Participants complete questionnaires when they are short, clearly timed, easy to open and reminded at the right moment, and when the site notices early if they fall behind. Engagement features can help, but the basics decide most of the outcome: a link that opens straight into the questionnaire, a sensible window, and a site that calls when a participant slips.
Capture builds those basics in: secure links by email or SMS with no app, reminders that stop when the task is done and respect quiet hours, and a dashboard that flags at-risk participants and overdue tasks. See ePRO compliance reminders.
What to compare
| Criterion | Why it matters | Capture |
|---|---|---|
| Compliance tools | Missing diary days are missing data | Windows, three-step reminder ladder, quiet hours, at-risk participants flagged |
| Device model | Cost and participant friction | BYOD in the browser with no app; clinic devices supported |
| Onboarding | Friction for participants | Secure link; no app and no password |
| Licensed instruments | Licence tracking and faithful migration | Licence number, holder and expiry per form; collection blocked if lapsed |
| Link to site data | Reconciliation effort | ePRO, eConsent and EDC in one study and one audit trail |
| Commercial model | Fit for your study size | Free sandbox; no setup fee; pay only when you go live |

Participant data
Participants open a secure link with no app to install. Diaries and questionnaires follow the schedule with completion windows, and reminders go out when a task is due, the next day and before the window closes, respecting quiet hours in each participant's time zone. Compliance is visible by study, country and site.
At-risk participants
eConsent
Participants sign on screen after confirming a one-time email code and acknowledging that the signature is legally binding. The investigator countersigns with password re-authentication. Witness and legally authorised representative signatures are supported, and each signature is linked to the exact document content.
Meaning of signature
I have reviewed this adverse event and confirm the assessment of seriousness, severity and causality.

Fit
Datacubed may fit studies where participant engagement design is the main priority and a separate eCOA system alongside the EDC is acceptable.
Capture fits studies that want strong compliance mechanics with participant data in the same study as EDC, eConsent and randomization.
One platform
Sites enter data on locked, approved forms with edit checks that raise queries at entry. Participants complete questionnaires on their own phones and sign eConsent with verified signatures. Randomization and kit management run in the same study, and everything shares one field-level audit trail.

Switching
Rebuild questionnaires in Capture, set windows and reminder timing to match the recall period, and test the participant journey on your own phone.
Switch at study boundaries rather than mid-study, especially for licensed instruments, whose electronic versions usually need the licence holder's approval in each new system.
Evaluation
Consent, onboarding and first questionnaire on a phone.
BYOD, provisioned devices or both.
Windows, reminders and at-risk alerts.
Who migrates them and how licences are tracked.
One audit trail or an integration.

All comparisons
Every comparison uses the same approach: what to test, where each option fits, and Capture's own answers. See all of them on the comparisons hub at /compare.
With completion windows, up to three reminders per task, quiet hours in each participant's time zone and at-risk alerts for sites.
Yes, for studies that want eCOA in the same system as EDC.
No. Questionnaires open from a secure link in the browser.
