Download the HowWeFeel App to help fight COVID-19

How We Feel App InterfaceDownload and help share HowWeFeel, a new app that uses the community’s help to track and fight COVID-19.

The app, which gained 170,000 unique users within the first week of its launch, was developed by an interdisciplinary, multi-institutional team of researchers including Harvard Chan School professor Xihong Lin, MIT professor Feng Zhang, Pinterest CEO Ben Silbermann, and others. Other key Harvard personnel participating in the project are Gary King, Director of the Institute of Quantitative Social Science, Junior Fellow William Allen, and Harvard Chan School faculty members Jukka-Pekka Onnela and Yonatan Grad, along with Epidemiology PhD student Christine Tedijanto.

In addition to helping health agencies better respond to the pandemic, you can also support the greater community the first time you download the app and complete a health check-in. For every unique user who signs up, HowWeFeel will donate a meal to people in need through the non-profit Feeding America.

To participate, download from the Apple Store or Google Play, and please help share with family, friends, and colleagues!
