Poker Tracker 4 is the most recent and sophisticated version of the program, which has been developed and improved over the years. Today both tracking programs belong to the same company, and the difference between those two systems is not as big as it used to be.
Poker Tracker, together with Holdem Manager, was one of the first software out there to help players track and analyze their game. The statistics allow you to adjust your game as you play. Based on that information, it creates various game statistics which can help to improve your game. It is software that records and stores hand information about you and your opponents.
