RealTime HUD

For helping my game I will use RealTime HUD. It's a program that watches your opponents for you. In a live game remembering every players move is much easier, so this is a great tool for online play. You can get it for free here http://www.holdemranger.com/realtime.html

it’s allowed on Pokerstars but I would have checked your sites rule befor applying it. Here are the rules for Pokerstars http://www.pokerstars.com/poker/room/prohibited/

as you can see "Holdem Ranger (including RealTime HUD)" is number 15 of the examples of acceptable tools and services.
