How many expenses do you really have on a daily basis that they are too much to track? I don't like a spreadsheet for this since they have bad input UX on phones. I use a custom app I built and even though it is manual I don't really feel it since I have optimized the UX for n=1 and it just becomes a habit. I tried all these other automatic tracking apps like monarch money,mint,YNAB et al but they are just not real-time enough for me and don't keep me in touch as much, also the obvious data lock. Maybe I'll make it public someday but I haven't mostly because the common sentiment online is 'manual tracking is too much work' when it really isn't if you do it as you go vs all at once at the end of month etc.
