Not to say this app has no use in adults, but it is clearly aimed at teenagers (I must have missed that in the description). I am finding it difficult to use as certain pages do not scroll; a tester needs to go through the app page-by-page and test every feature, so one does not miss identifying something for themselves. That said, there are great things to start with in regaining control (oops, sort of, in certain situations, ah you know what I mean...) of your anxiety.
