Are HM2 and PT4, HUDs?
Holdemmanager (HM2) and Pokertracker (PT4) are tracking of all your hand histories, so you can also use these programs to keep track of your results, re-view hands and graphs.
Back to the HUD. These programs have HUD's and as mentioned both programs have some default HUD setups that you can use, in the beginning you should just stick with the most simple stats like VPIP and PFR until you learn to understand how to use the stats.
Personally I prefer Pokertracker (PT4) I think they have the best HUD's, but both Holdemmanager (HM2)and Pokertracker (PT4) have free trails, so you can try them both and see which one you prefer.
