The problem Dorona solves

1. It provides the user to track himself and other members with GPS so that one can know the proximity for the covid positive patient and can be informed.
2. We also trained the model and provided in our app which can classify the chest X-ray for Covid, Normal, or any other lung Infection
3. Every user is allotted a QR code which can be scanned to know the COVID status of the user. This can make easy passing on various stations and airport.
4. Users can find News and Updates related to covid in our app.

Challenges we ran into

in Android 8.0 and above, We cannot access location in the background or when the app is terminated so to solve this problem we have to start a foreground service that will fetch continuous location updates and passes it to the server.
While Hosting Api on Heroku we had to figure out that we had to make multiple buildpacks as two languages and their dependencies were involved. To figure out this, it take a lot of time.
