Developers at a Croatian development firm created an app called Homebound that uses vibrant colors and beautiful interfaces to help users cope with COVID-19 isolation, allowing them to collect contact tracing information and stay engaged through gamification and chatbot interactions. The team built the app in just three weeks using React and Firebase as its backbone, and it won an award for best COVID-19 communications tool at a hackathon. The app's design prioritizes user experience and mental well-being, with features like SMS integration and a chatbot named Couchy that responds to user questions about the pandemic. The developers' goal was to create something out of the ordinary while still addressing the pressing need for contact tracing information during the crisis.
