Welcome to ReWi. Learn to rewire your daily habits and live a happier life.

ReWi is an app developed for students in Dr. Laurie Santos’ wellness course, taught at Yale University as a semester-long course (“Psychology and the Good Life”) and online as a Coursera course (“The Science of Well-Being”).

The app allows you to track eight activities that are known to promote well-being. These include sleep, exercise, meditation, goal setting, gratitude, kindness, social connection, and savoring. All of these practices are based on psychological research suggesting that increasing these practices can lead to increased happiness. You can choose to log responses for any of the wellness activities at any given time on a daily basis. The more you log, the more likely it is that you will establish long-term change! Logging becomes easier the more you do it.

Track your progress with:
* Daily streaks
* Total activities logged
* Calendar view of each activity
* Bar chart view of all activities tracked over time

Beyond merely tracking activities, you can even practice several activities on the app itself such as listening to meditation tracks and visualizing effective goal setting with a rotation of prompts.

While there are many existing wellness-related tracking apps out there, ReWi houses all the course-specific wellness activities all in one interface. The course team designed ReWi with the hope of facilitating positive behavior change.

Please be aware that app usage data may be used for empirical research and you will be asked to give consent within the onboarding screens of the app. Consent is completely optional and you can use the app without opting in to research.

Terrible App. Crushes each time I try to add a picture.
Pretty useless...

How can I revoke consent?

An important part of informed consent is making sure people know what they are agreeing to, and allow them to revoke it at any time. You highlight your “Agree” button in blue (biasing people to click through and agree) and then do not provide a clear link to revoke consent if it was accidental or if the user changes their mind.

Making both buttons the same colour, prompting for confirmation of the choice the user makes, then clarifying how to revoke consent at a future point are easy fixes...
