If you prefer RSS (or JSON) over email, my http://hnapp.com works well, and it's open source too.

Thank you for the link. Is there a way to have more results ?

There isn't an option to get more results per page, but you can get to the next page by clicking "next" at the bottom.

If you don't see the "next" link, then there are no more results. Note that hnapp only has data since around August 2014.
