Hi,
i do use software..PT4 (poker tracker 4) Heads up display and it is helping my game enormously..statistically when looking at opponents style of play, how many
hands do they play, what position do they play from and what is their bet sizing...plus many more..
There is a lot of software out there..im always dubious on pro endorsed software and tend to look at what systems are used widely and not for personal benefit.
I would advise you to identify what areas of your game you feel need improving, sometimes software is not the answer!
Best wishes
