Your splash page is very bland, having looked on http://dinnerplanner.net http://dinnerplanner.net there isn't much on it other than 20 words. I recommend that you make your splash page/landing page better by adding more information, or even a few screenshots etc to hep encourage signups to your service. However, this seems more of a marketing issue. You should focus more on your marketing efforts as well as, how your competitors marketed your product? Also you should consider contacting publications such as a food blog etc, as this will also help you acquire more signups.
