Alex, I wouldn't be worried of the app harming someone so much as someone hurting themselves and their family blaming it on you or your app in a search for a cause of their loved one's suicide. Add in a lawyer who smells a case, and you could wind up in legal trouble quickly without actually harming anyone. Don't give up on it, just shield yourself appropriately. As far as waiting until you are successful to do this, there's really no way for you to tell what mental state a purchaser of your app is in, and however unlikely it may be, a tragic scenario similar to what I described above could happen to one of your first users. I think in your case it would be wise to protect yourself now instead of waiting.
