Key metrics include: click-through rates, and conversion rates to evaluate which version (A or B) is more successful

Recruitment rate (number recruited per month)

The recruitment rate will be defined as the total number of participants recruited divided by the number of months of recruitment divided by the social media cost to determine the approximate number of participants recruited in a single site per month.

Adherence to app reminders (proportion of app reminders)
