Any number of players (up to 12).

Some odds calculators limit you to for example just 5 or 8 players.

Enter specific cards for players or leave blank (random cards).

Some odds calculators require you to enter specific cards for all players, so they can't analyze e.g. AA vs. a random hand as PokerCruncher can.

For the board enter just the flop (turn and river random), the flop and turn (river random), or all 5 cards, or leave blank (all 5 cards random).

Specify hand ranges (sets of hands with optional weights) for players. More

This is a powerful feature that you won't find in most other odds calculators. Poker is all about making good decisions based on incomplete information; hand ranges enable you to model this.

Specify dead cards.

Some odds calculators can't do this.

Fold players out of a hand at any point.

Simulate all the way to the river (normal, complete simulation of a hand) or do partial simulation to the flop, turn, or even just the hole cards (preflop). More

This is another powerful feature that you won't find in most other odds calculators. Most other calculators can only simulate all the way to the river and so can't tell you e.g. how often a suited connector flops a flush draw or straight draw, or how often AK/AQ/etc. make top pair on the flop.

See players' win/loss/tie odds, equity%, and hand histograms (odds for making OnePair, TwoPair, 3OfAKind, etc.). Also see the winning hand's hand histogram, in addition to the players' hand histograms.

Most other odds calculators don't give you this many stats.

See other stats like odds for draws and odds for making top pair or an overpair (useful when you do partial simulation to the flop).

Most other odds calculators don't give you these stats.

Graphical display of stats, in addition to text display.

Settings for the number of hands to simulate and for how frequently the Sim Results screen updates so you can tailor the simulator to your phone's speed. Also, control what information is displayed in the Stats screen. In addition, PokerCruncher has a Small Screen Mode setting that formats the odds and stats so that they're easily readable on even very small phone screens.

Monte Carlo simulation; solves any Hold'em scenario using random number generation. The results become more accurate as you simulate more and more hands. However for postflop situations with specific players' cards, PokerCruncher does complete enumeration of the remaining cards to compute the exact odds and stats. More

Some odds calculators don't do complete enumeration for any situation and so aren't able to compute exact odds and stats even for simple scenarios, like in the example below.
