It depends on what the app does though. One of the ways people cope with things like that is escapism. If your app can provide that then it can help some people. Eg a game or an app for stories, jokes etc. Another thing that can help with depression is exercise. But it's difficult to exercise while depressed. If you can somehow build an app that tricks people into exercising (like Pokémon Go "tricked" people into going outside) then that could help too. It's not as weird as it sounds.
