HAPPI

HAPPI is part of a research project at Stockholm University that studies happiness, well-being and productivity. This app has three uses during the research project:

1) collect self-reported baseline data about the participants.

2) deliver the experimental treatment, and, after the experimental period is over.

3) collect new self-reported data about the participants.

The app does not collect any information about the participants outside of the self-reported data, and all of the collected data is handled anonymously within the app with help of randomized user-ids that cannot be backtracked to individual users.
