Sponsor's own description
The study will test two interventions for increasing engagement with a target behavior, delivered via a digital web application that participants can access using their phones or computers. For example, in the streak group, users would see how many consecutive days they have completed daily lessons and will be encouraged to extend their streak. In the tally group, participants will see how many cumulative days they have completed daily lessons and will be encouraged to extend their tally.
