Swapna and team, Congratulation, I really like your idea, maybe a new feature could be: Suddenly people can select the current mood or an ideal. For example, if a person suddenly feel sad and want to feel better the app could suggest a particular healthy food. I know that bananas for example, have high levels of potassium, that help to feel better. In Colombia, if you feel sick people recommend to eat guayaba (a typical fruit) for its high levels of vitamin C. Perhaps the app could suggest strategies to deal with flu.
By the way, your communication skills are very good.
