In order to help with the pandemic response, the Pitt Smart Living team at the University of Pittsburgh has built a mobile-friendly web site to help Pittsburghers share information about: 

(a) whether items are out of stock at different grocery stores (crowdsourced), and 
(b) how busy each store is at any given time, to help people choose a time to visit when stores would be less crowded (using Google data). 

Please help your neighbors by contributing data whenever you go to the grocery store! 

The website can be accessed at https://www.got-toilet-paper.org/ No download or registration is required. Additional information is available at https://pittsmartliving.org/2020/04/15/got-toilet-paper-website/
