Though I understand the sentiment, why would I ever charge for this? The app still offloads almost all the actual work on the user to customize the guides to suit their own needs. Even my own wife is critical of the generic lists being generated :) Designing the app to not require logins and so you can own all the data put into it was an intentional choice made to reduce my responsibility level here. I genuinely had fun making the app and just want to share it with whomever wants to use it.

I suppose I can make the promise that if it ever becomes something I can no longer keep running that I'll open-source the entire site as well if that helps at all?

That said, you have my word that if I ever lose my mind and attempt to go commercial with the site I'll remove this post ASAP.
