Design an app for a community of Celiac disease patients.

Firstly, I would like to understand what is Celiac disease from the interviewer. I understand that it is intolerance to Gluten. Also, I would like to know if we are looking for web client or mobile client or both. 

Assuming, we are looking for a mobile client only (also because mobile usage has 70% penetration as compared to web usage of about 30%, so I would like to focus on the mobile app).

The Primary customers for this app would be patients (suffering from Celiac), closed ones/family members of these patients. The secondary users of this app would be Doctors (experts in curing this disease).

The use cases of the app would be:

1. Readily access of information related to Celiac disease
2. Accessibility to Doctors
3. Information on Food items

1. Creating a city wise repository of Doctors (along with their information of clinics and operating times) who treat this disease
2. There would be an information repository on the treatment of celiac disease
3. On-boarding Doctors who would monitor chats and provide online advice. This advice can be through one-one chats with the available doctors
4. A group chat portal that would be used to seek advice from anyone (even from other patients) - This chat portal would be open to all the community members including Doctors
5. A page that would enlist all the packaged food that can be consumed (accounting for gluten sensitivity). 
6. There can be provision to order and deliver the packaged food
7. A section of app would enlist the home made recipes to treat the disease or generic recipes that are recommended for a Celiac patient
8. There can be a section in the app that enlist over the shelf medication that can be purchased for patients

• Time to market/Effort required
• User impact
• Cost to build that feature
• Any specific management strategy
