Sr CRA

Overall experience with Castor is extremely positive. I think the customer support has been great and I really enjoy the company.

Clinical Research Associate

Easy data download process, great interface, and very affordable compared to the other EDC systems out there.

Research Coordinator

Very positive and would definitely recommend if given the opportunity.

Patients manager

It offers a wide variety of tools to validate data entry. It's cost-effective and the fact that one can practice and customize and test before the "go live" is a great advantage.

Clinical Project Manager

The tool was easy to learn thanks to a few, short instructional tutorials and a great FAQ.

Clinical research coordinator

Very user friendly, easy access to online help (email), audit trail available, ease of uploading documents, data editing easily without having to unlock pages constantly.

PhD Candidate

Castor is very user friendly and I loved working with it.

PhD candidate

The structure is intuïtive, solid and runs smoothly which is very important for multicenter research. It helped me significantly in my work as project manager of an international multicenter RCT.

I enjoyed the great level of control when building forms, and even managed to do some coding - and to test that code to make sure it really worked.

There are a lot of features and I would not change anything. The Castor helpdesk was very helpful and responded very quickly when I needed help.

Bio Medical Engineer

The randomization is only in blocks and there is no other options for randomization which is a little problematic with a small group trials.

Program Director

Ease of setup, ease of use and overall has all the functionalities we need for clinical trials.

Clinical Research Assistant

For advanced users, there is no accessibility to more powerfull programming to manipulate the platform. The image/file upload feature is very restricted in file size.

Some building blocks are a bit limited in how they can be used. For example, some can't be set as "required", so one has to create additional fields to achieve the same result.

Overall the system is good, it does it's job and worth the cost. I think simplifying the building proccess and making repeated measures display a bit more informative would be better.

Clinical Research Director

The stats page doesn't allow scrolling, which means I often loose half the information. User experience of using the system across different smart phones is variable.
