Join FreMEn contra COVID

Join our project FreMEn contra COVID, that came to life in the Chronorobotics laboratory of Czech Technical University in Prague in cooperation with the global scientific community.

Help us, as well as yourself, in the fight against the coronavirus epidemic. Unlike today's mainstream ideas, we chose prevention over restriction, privacy over surveillance, and volunteering over obligation.

Our system is based on a method called FreMEn, which is capable of forecasting the crowdedness of various locations hours and days ahead. Thus, it can provide recommendations for safer navigation in a world saturated by the virus.

The forecasting system cannot work without data. We need you to participate in a strictly anonymous collecting of crowdedness of locations of interest like parks, playgrounds, or shops. The collected data describe places, not people. Thus, the collected data do not pose a threat to privacy.

Join us! Become FreMEn! Install our app, help us build an engaged community, and help those who are vulnerable!

Where do you measure

This map is only illustrative! All displayed data has been modified and their accuracy is bellow 1 km.
Thus, exact location of individual points is irrelevant. What is interesting is the overall distribution of collected measurements.
