PokerTracker

My volume will be on zone so the hud isn't applicable. I also like my hold'em indicator hud fine for regular speed tables. I just want to use PT4 as a database for myself mainly and to look over certain tough spots. I figured I'd play and then come back later and manually import once I can see all the cards. I'd assume that works fine but wanted to ask.

Yes you can import manually downloaded Ignition hands into PokerTracker 4 using 'Play Poker -> Get Hands From Disk'.

I read through that. Thank you. I'm still unclear if I need to have PT4 running while I play (if I don't want to import hands right then) or if I can just turn it on when I want to manually import after the hole cards are shown.

You don't need PokerTracker 4 open while you play and you can just start it whenever you want to import your downloaded hands and/or review your database.
