How are participants charged?

Can I add participants or add-ons later?

Yes. You can add participants in groups of 10 at any time; each group of 10 is added to your monthly price from then on. Add-ons can be switched on at any time during your subscription.

What is Engagement analytics?

An add-on that records how participants use what your team builds: the time spent on each page of an intervention or content item, how much of each video they watch, and how long each questionnaire takes. Use it to report intervention dose, adherence and data quality. Learn more.

We need more participants than the calculator allows.
