Due to the Covid-19 virus it is expected that supermarkets will allow to enter only a handful of people at a given time period. This means there will be waiting queues in front of the supermarket. To help reduce the spreading of the virus, people on the waiting queue could use a web-app to warn others of the queue by simply pressing a button. Others will see on the web-app how many warnings are for this supermarket and might decide to go to another supermarket or wait at home. The principle is already implemented in anti-traffic-jam apps with user generated content.

What it does

Help people stay informed of long waiting queues at supermarket.
