I understand this point of view - why shouldn't people share things that have helped them? - but that's why we regulate things like cures for diseases. Taken to an extreme, "here's what helped me" leads to cancer "cures" being hawked all over the internet. To me this app falls somewhere in between "here's how I quit procrastinating" and "here's how I cured my skin cancer." I can say from experience that social anxiety is not always easily treatable, even by your average therapist, and specialists in it have valuable knowledge that I think it would be wise to take advantage of if you're publicizing a treatment.
