Every invalid entry a survey accepts turns into a coordinator’s follow-up call later. Castor’s eCOA platform supports app-based and browser-based ePRO, so participants answer on a provisioned device or on their own phone. See how the browser route works: a participant opens a survey link sent by email, SMS or messaging app and answers with the same real-time validations you built in your electronic data capture system.

Invite participants by email, SMS, WhatsApp or an app push notification, then follow up with timely reminders.
Catch invalid answers on the participant’s screen, where a future date is rejected before a coordinator chases it.
Ask only the questions that apply, using conditional branching, sliding scales, multi-select checkboxes, and embedded images.
Reach participants in their own language, with multilingual capture across web ePRO and the patient app.

Give participants a link and let their own phone do the rest. See exactly what they see before you go live.
