I worry that these apps encourage people to catastrophize things, which is good for their profits, and bad for the mental health of their customers. I find it difficult to imagine a scenario where one of these app makers doesn't find a mental health issue that you need help with (and to pay them for). That sort of "diagnoses" can cause you to develop the disorder that they have diagnosed you with.

There is a term used in a theraputic setting called catastrophizing: https://www.psychologytoday.com/us/basics/catastrophizing

It's an extremely treacherous situation.
