Are you thinking of a way to automate the actual tracking? Do you find it a hassle to do manually? (this is the main thing I was trying to solve, check out https://www.t12n.io )
I thought about having some periodic reminders, maybe using something in the spreadsheet (e.g. columns) as prompts or questions to be answered, but have not implemented anything yet. I am pretty disciplined myself so I rarely forget to write down an expense after I put my wallet away, but I can totally see that this is be a pain point for some users.
I could add a feature like that, but I do not really have lots of users to get feedback from, yet. I am currently in the "tell people" stage after I "did things" [1], so I should probably try to make a landing page as cool as yours ;)
I mainly use it to track expenses and random thoughts or links.
