Why poker players use calculators
Poker is a game of decisions under uncertainty. Calculators take the guesswork out of the math so you can focus on playing well. Use the odds, pot odds and EV calculators to study hands away from the table, and the bankroll, variance and risk of ruin calculators to protect your money from normal downswings.
From calculators to tracking
Calculators are only as good as the numbers you put in. To know your real win rate, ROI and standard deviation you need to track every session. The free Poker Tracking web tracker works these out automatically from your own results, and iOS and Android apps are on the way.
Are these tools allowed while playing?
Bankroll, win rate, ROI, profit and payout calculators are fine to use any time. Using equity or odds calculators during a hand is not allowed on most online poker sites and in casinos — use them to study between sessions.
