This app collect users' anonymized location data (once permission is granted) and compiles this data in a cloud database. This data is used to generate in a realtime heatmap visualization of crowds in the University of Washington campus area. This visualization is rendered in both this native app and a separate web app. Furthermore, when the native app detects a user's location is near that of a sufficiently large crowd, it will notify them to remind them to wear a mask.
The ability to see crowd density in realtime can help people avoid large gatherings.
Check out the web app repository and the integrated repository with the latest versions of both the native app and web app. Any further development will ocurr in the latter repository.
This project was submitted to the Hack-20 hackathon on August 15-16, 2020. Check out the DevPost submission!
