I thought of a tablet app, but the stakes were too high, so it wound up as a laminated paper. You can read about my design decisions here:
Is there a reason besides preventing commercial use that you don't just have a PDF link on your site?
I wish you all the best for your mother. Keep caring for her, before caring for the website.
I don't know what skills you lack, but if they're web development skills, and if you want some help with your wonderful project, my email is in my profile. I cannot, alas, do anything about your insufficient-time problem.
I guess this is why doctors don't treat loved ones. I was doing outreach, it never occurred to me to go back and check my site with fresh eyes. I wonder how many people I missed helping.
A downloadable PDF would be more useful, sure, but already with what's up there, relatively-low-skill users could print the whole page and cut it up. And higher-skill users can read it to follow your thinking to get inspiration and kick-start their work on a similar solution. So even if you never add one more thing to that site, and even if all that happens is half a dozen people a year randomly find it by lucky google query, it's STILL a meaningful contribution to other people that you've made your thinking and your output available. You're already doing good work, both for your mom and for strangers who you'll never know you've reached.
Hugs for you, internet person, and high fives.
And, again, if you want any help with making a dynamic version, hit me up, email in profile. I'd be proud if I got to help this project in any way.
