Interesting. I'll add my email. I have been working on an open-source, self-hosted recipe/calorie tracker dealy that my spouse and I have been using for macro tracking during weight training. Haven't put much effort in to "advertising" it but we have been using it quite successfully for a few months now.
EDIT: side note -- when signing up for the email the MailChimp landing page has a "return to site" button that points to "https://sites.cx/" (which is an NXDOMAIN for me).
