This might be a good app, I honestly wouldn't know. But if you're making claims like the one above please link to the actual research. Preferably on the page itself.

Fortunately I'm not depressed and the actual validity of this app isn't critical to me, but for people who are suffering from depression I think it would be. Making such a claim without any reference to the actual research seems dishonest to me, potentially being dishonest against vulnerable people.
