As we know, weather dependence is not an official disease, which means that the area of science around it is little studied.
This may mean that the general market and target audience for this product may have low awareness and immersion in the problem it solves.
Despite this, those users who already have that unofficial diagnosis, have their own experience of living with the disease, which they can share with less knowledgeable users, enhancing both immersion in the problem and the product as its solution.
A possible solution is to offer users a general chat in which they can unite around the discussion of the problem of weather dependence and the treatment of diseases that are provoked by it.
This chat will help retain current users who can share their experiences and diagnoses from doctors, as well as attract new users who have questions and no answers.
