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.

Yale made this?

Not very useful even with the course. The app just has you track things. No interactions with other users, or accountability. If self reinforcement is your thing than this is for you but it’s just an extra step that isn’t all worthy. Could be better if it was interactive with other users or if there were tracking goals or something to meet other than just a bar graph of things you did ‘right’ during the day

I want to give this more stars!

I’d love to get into this app to see how well it works with the course and give t more stars based on its actually functionality. Alas, I am stuck at a login screen that demands either google or Facebook integration. I am not “on the privacy bandwagon” as other reviewers may insinuate. However, I prefer not to have to wonder if I can trust FB or Google will not misuse my data nor suffer a breach. I prefer to keep deprecate independent logins for the apps and services requiring authentication. Please update your app to support this basic requirement and I will happily re-download and provide a fair and honest review of the app on its merits rather than its lack of sufficient means of access.

I really would like to give this app more stars

I really would love to give this app more stars, but it isn’t working. I am stuck on the sign in screen trying to get in and it just simply closes. Funny thing too was that it worked the first time and I was able to print out my work book for this course, but today it’s a no go. I was looking forward to having the helper and the other features that it offers. I’m sure it’s a five star app when working.

Please check and see if there is a glitch that can be fixed. Thanks and look forward to using it when it is working.
