There are some tools and services which have legitimate uses for analysing your game, but which are not appropriate for use during play. For example, ICM (Independent Chip Model) and Nash Equilibrium tools may be used for post-game analysis and for studying hands which you have previously played. Also, there are some web-based results databases, and its fine to use these to look at your own results. However, you may not use such a tool while the PokerStars software is open.
Some examples of tools and services which are prohibited only while PokerStars is running are:
Insight Poker Hound*
PokerAnalytics
Poker Player Winnings
PokerStrategy ICM Trainer
Real Poker Rankings
SAGE Decision Calculator
SharkScope (including SharkScope HUD)
Short Stacking Strategy Calculator
