Hello Sir,
Hope you have been fabulous :)

First I appreciate your idea behind the app because this app will be helpful for a society.
1. Do you have any specific UI for the app or it will up to us?
2. Do you have any preferences for the back end?
3. What features do you need in admin panel like total no of blood unit for a particular group, edit, add, delete, modify etc?
