How it works
Poker looks like luck, but good players win because they make better decisions with the same cards. Every decision comes down to a little math and a read on your opponent. This app teaches both, in plain language, so you can start from zero. Here is everything you need to understand what the tools are doing.
Six ideas cover almost everything. Learn these and the rest of the app will make sense.
Equity
Your chance of winning the hand right now, written as a percentage. If you have 40% equity, you win about 4 times out of 10 from this point.
Outs
The cards still in the deck that would improve your hand into a winner. More outs means a better chance to catch up.
Pot odds
The price you are getting to keep playing. If you must pay $25 to win a $100 pot, you are getting a good price and only need to win about 20% of the time to break even.
Expected value (EV)
Whether a decision makes money on average if you made it many times. A play can be correct (positive EV) even when it loses this one time. Good poker is about making +EV decisions, not about any single result.
Ranges
You never know your opponent’s exact two cards, so instead you think about the whole set of hands they could have. That set is their range.
Reading opponents
Narrowing an opponent’s range based on how they bet and act. This is the real skill, and it is the thing most trainers skip. This app is built around it.
Each tool trains one part of your game. Here is what every one does and how to use it.
Hand Replay
A poker hand plays out one step at a time. At each big decision it pauses and asks you to read your opponent, then choose call, fold, or raise.
- 01Watch the hand deal out. When it pauses, look at the pot size, your cards, and how much you have to pay to stay in.
- 02You will see a grid of all 169 possible starting hands (pairs run down the middle, and an "s" means suited, an "o" means offsuit). Tap or drag to paint the hands you think your opponent could be holding. That is your read.
- 03As you paint, the app instantly shows your equity (your chance to win) against that exact read, right next to the equity you would need for calling to be worth it.
- 04Pick call, fold, or raise. The app then reveals your opponent’s real hand, scores how close your read was, and explains the right play in plain language.
- 05You earn points for good decisions and accurate reads, not for winning the pot, so you are rewarded for thinking correctly even when the cards do not cooperate.
What you learn: How to put an opponent on a range and turn that read into the mathematically correct call, fold, or raise, and why it is correct.
Equity Visualizer
A colored grid of all 169 starting hands. Green hands are strong, red hands are weak. It shows your chance of winning with each one.
- 01Look at the grid. Pairs run down the diagonal, and the color tells you how strong each hand is.
- 02Click any hand to see its exact win percentage.
- 03Drag the range slider to change how many hands your opponent is holding and watch your numbers update instantly.
What you learn: Which starting hands are actually strong, and how their value changes depending on what your opponent could have.
Mental Math Blitz
A fast 30-second quiz game. Quick poker math questions flash on screen and you answer as many as you can.
- 01A question appears, for example "the price says you need 25% to call, you have 40%, is it a call?"
- 02Tap the answer before the timer runs out.
- 03Keep a streak going for bonus points. Miss three in a row and the round ends.
What you learn: To do the key poker math fast enough to use it at a real table, without a calculator.
Equity Calculator
A quick answer machine. Enter your cards, the board, and what you think your opponent has, and it tells you your chance of winning.
- 01Pick your two cards.
- 02Add the community cards on the board (as many as are showing).
- 03Set your opponent’s likely hands, then read your win percentage and whether the price you are being offered is worth it.
What you learn: Whether calling a bet is a good deal in any specific spot.
Tournament Lab
Tournaments have their own math because your chips are worth real prize money. This trainer teaches the push-or-fold decisions that decide them.
- 01You are given a tournament spot with a short chip stack.
- 02Decide whether to go all-in or fold based on your cards and position.
- 03The app shows the correct play using tournament prize math, not just raw card strength.
What you learn: When to shove all-in or fold near the money, where most tournament mistakes happen.
Adversary Lab
A place to build a model of a specific opponent, for example a regular from your home game, by answering a few questions about how they play.
- 01Name your opponent and answer six simple sliders (how many hands they play, how aggressive they are, and so on).
- 02The app turns that into a realistic set of hands they tend to hold.
- 03Train against that exact style and see how your best plays change to beat them.
What you learn: How to adjust your strategy to exploit the real people you actually play against.
EV Dashboard
Your progress report. It tracks the quality of your decisions over time and points out your recurring mistakes, called leaks.
- 01Play sessions in the other tools. Every decision is recorded automatically.
- 02Open the dashboard to see your accuracy, your points, and where you are losing value.
- 03Follow the suggested drills that target your specific weak spots.
What you learn: Exactly where your game is leaking money, and a plan to fix it.
