Anyone using spreadsheets or apps to track bets properly?

been thinking about getting more serious with tracking wins and losses. right now i just jot stuff down on my phone notes but honestly it gets messy and i forget half of what’s actually in play, especially after a couple days of sessions mixing poker and slots. i hear people talk about keeping spreadsheets or using apps but not sure what actually works best, especially if you play a mix of stuff like me and bounce around between sports bets, some blackjack, and random slots runs.

i’m not super disciplined about putting in notes right away, so i wonder if there’s a lazy-proof way to do it without just cluttering up my phone again. also interested in stuff that doesn’t take forever to set up, like i don’t want to build out formulas or whatever on my own if i can avoid it. anybody got suggestions? do you notice any edge from tracking, or does it just feel like extra work without much benefit?
