Do you mean for live poker or online?
For live, I’ve seen in Brad’s vlogs that he’s using Poker Income. Very nice app that i used to use as well.
I changed cellphone and switch o.s. from apple to android and couldn’t find a way to transfer my data, so now I’m using Poker Bankroll Tracker. Works super well, i love the app, it’s beautiful and all.
As for online poker, I used to use Poker Copilot on my imac, works super well. I just kinda stopped playing online a few years ago. I know poker tracker and/or hold’em manager work pretty well too.
Good luck at the tables 😉
