> It has a login and extensive help info, so is clearly targeting far more than his wife.
I tried to find the part where OP was turning this into a business and trying to market it to customers. I assumed this was like most other "Show HNs" and was simple something someone created for his wife and decided others might find it interesting or useful.
> Why the downvotes? I wrote "Gives the impression", which is valuable feedback for someone trying to design an attractive product.
Because your post gave the impression that you were misrepresenting what was fairly clear to many others. You are also giving the impression that you know far more than you actually do. You are finally giving the impression that Show HN is not the place for this. Frankly, all your comments give the impression of someone who isn't honestly contributing to this discussion.
That's probably why you are getting down votes. That, and your lack of HN etiquette.
