I see. That's quite easier to do when you have a website set up in order to do all of the tracking, in comparison to relying on an Excel spreadsheet, which is best updated on a PC. Your set up makes me wonder what I could do to replicate something like this using a VPS and a subdomain on a domain I have, actually.

As for water consumption, I suppose it'd be a lot more rewarding to implement it into your current workflow for entering all of the data. In my case, I could look into using Apple's Shortcuts to let me have a button that I can press to quickly add data to the Health app, especially since I usually drink water in 500ml increments. I could always have the shortcut ask me as well - but then the whole process would become significantly slower.

How do you make sure that you always remember to tap the correct action? I’ve kinda always wanted to do something like this - maybe tracking every hour instead of every minute - but I’ve always been too afraid that I’d miss out on tracking something. For example, I’ve been wanting to keep track of how much water I drink using Apple Health, but consistently forget to add that I’ve drank 500ml or something. I have seen success in tracking habits in the past, but even then, it’s just an Excel spreadsheet with a cell for every day of the year and then numbers, reflecting the kind of action tracked and the amount of times per day, in the adjacent cells. That’s kinda easier on me, since I can update the spreadsheet from once a day to once every 3 days and still successfully recall everything of the top of my head.
