Coronavirus Danger Localizer is Progressive Web App to help in the fight against coronavirus in the world. The application is fully responsive, working in inactivity mode and fully adapted to mobile devices. The operation of the application is based on the geolocation of users who, when registering or in the panel of their account, can choose permission to track their location by other users because they have a coronavirus or there is a suspicion (regardless of the indications) that they may be carriers of the virus. By sharing this information and allowing others to track your location (this permission can be turned off ANYTIME!), other app users see red moving points in their area - users suspected of having coronavirus (or having it). Thanks to this, they can bypass such users or plan a special route that minimizes the risk of contact with the carrier of the virus. Register and help others now! The more we are, the greater the chance of defeating the virus!
