What reviewers say
Easy Form Design with Reusable Studies and CDISC ODM Coding
“Ease of use when designing forms. The ability to reuse forms across different studies. The ability to include CDISC ODM codes. The ability to assign codes to response options.”
Easy-to-Use Study Builder, but Limited for Complex Trials
“Viedoc handles data capture well, and I like the user-friendly screens. As a study builder, I can create studies a bit faster. I also like the signing features and ePRO. ePRO gives patients a much better experience than the other EDCs we use. The signing features work quite well ”
Intuitive, User-Friendly, and Backed by Exceptional Support
“It's very intuitive to use. User friendly. And the support team is exceptional”
