Challenges we ran into

1. Handling On-Spot Registration if vaccines in a particular day are leftover, it was solved by two types:
- Push notification to users registered for the next day and assign the vaccine of the rejected user to the users who accept the notification.
- If any user is registered with CoWIN and not with our service, the health official registers him on the spot and marks him vaccinated.
2. Finding a suitable Map API that works with our use case.
3. Deciding the parameter for 'area' as a standard, which was solved by:
- We generated coordinates for a particular locality by using a maps API.
