How do you prefer to track things? Other than trying to track things entirely mentally.

I'm still trying to learn how to take orderly notes as a GM, but I find just scratching things down in my notebook as conditions and the like crop up effective. And when tracking in combat, I use a grid to track rounds, with HP in the cell, and sub-scripts and super-scripts to track negative and positive status bonuses, respectively.

Things end up looking like the periodic table.

Though, really, it's the players responsibility to actually keep track of their buffs and debuffs. I just track to remind myself to ask them.

I also haven't bothered to give a damn about any of the remastered rules yet. I print off spell lists from pf2easy, and players are responsible for knowing how their abilities work. I'm just there to determine whether they apply in the given situation.

Also, what things can you get away with just not tracking? I dropped most secret checks right away, because my table didn't like them, and it gave them something else to burn heron points on. It takes away the element of being unsure if you've been spotted or not, but there are other ways to inject that back into the game.

Try a Pathfinder 2e character builder like Pathbuilder. The character generator on Demiplane is also very nice and has all the automation bells & whistles, but you need to buy the books for most options like in D&D Beyond.
