The problem Covid 19 Risk tracker solves

The problem we intend to solve is that people are unaware when they come in contact with the person who is suffering from covid-19 at risk of covid-19 so we have created an app that notifies you whenever you are near a High risk person.We have also added several other features to help people in this crisis like nearby test centers, grocery delivery, hotspot map ,chat bot for queries, news and stats of covid so all the confusions are cleared.We solve the problem by creating an all in one android app
The app combines everything from tracking your contact with a person at high risk, to hotspots around you , it shows you stats,news and answers your queries.
The following are the key features-
-Health Risk analysis
-Realtime updates in form of notification
-Interactive hotspot Map
-Warning and reporting system against risks and gatherings
-Resources and healthcare locator
People can feel the effect by avoiding places or people the app notifies against it also makes life easier by showing all the info at one place eradicating false news.
React-native, JS, Android, Firebase, IOS
Firebase is used for its speediness and versatile features including security, React native is used to make the app cross platform for Android and IOS
The solution was easy enough that it was made 80% in 3 days time hence it can be made to deploy at the earliest by ironing out some kinks
The app is pretty scalable as the backend is already in place and is cross platform so no bars there.

Challenges I ran into

Developing an algorithm to appoint a risk grade.
Tracking location data.
Fetching nearby stores
