The problem VaiRoga solves

Epidemic spread prediction
As we have a centralized database of each person in each region we can easily mark each region with spread of COVID-19 and also we can easily monitor and predict spread of COVID-19. This can also help gov. to take precaution beforehand.

Fake Doctor prevention
In this pandemic time, there are many fake doctors especially in rural region who gives wrong medicine without proper prescription but we have database of all authorized doctors. So we can prevent the problem of fake doctor

Prescription availability
In this pandemic time, all doctor is very busy due to high number of patients in hospitals and COVID-19 tests requires many pre-tests but in our app/web ap we have patient's medical history which will help doctor to give medicine fastly and attended other patients. Due to availability of medical history any nurse or compounder can also give medicine to Patient which will reduce load on Drs.

Health score
As we have credit score for loans we can introduce health score for life insurances to prevent defaulters. As treatment of COVID-19 is very costly so many people take loans or life insurance but due to all paper works and checking it takes too much time to pass insurance but with this health score insurance company can give loans on the basis of their health score instantly

Emergency situation
Suppose if a person met with an accident while driving but due to pandemic there is to much rush in hospital and doctors cannot give any treatment before any tests to the person who met accident but in our app/web ap we have a section of QR code scanner where the QR code of patient's radar card will be scann and this will give all medical history of that person which will help dr to give him right treatment very easily and fast.

Doctor assistant
Using probability-based modal we can predict disease's test using symptoms this can prevent the problem of dr. unavailability in ruler area and it also does the cost-cutting by limiting the no. of test.

Challenges we ran into

1. storing the centralized data between the android app and the web app.
2. working with API.
3. backend connections.
4. regular crashing of the app while calling API
5. working with jquery
