I think a couple posts here already briefly cover the concept: "Have a calendar view for entries in the journal" or "Track number of times entries logged in journal", but I would be curious to see more stats on the habits themselves and maybe even correlations between those.

For example, "if you drink enough water, your daily calories are lower", "if you do a chiropractor session, you are more likely to take a cold shower", "if you don't have device in bed, you have higher chance of reading before bed", "you are more likely to consume more sugar when you're menstruating" etc.

On top of how those habits influence health scores, it would be interesting to see if there are any correlations between those habits.

Thanks!
