About this app

Preflop Lab helps you build and memorize poker preflop ranges so you stop second-guessing your decisions at the table.

CREATE YOUR RANGES
Tap the 13x13 hand grid to assign actions (raise, call, fold) for any spot — open raise, 3-bet, squeeze, push/fold. Or paste a range string directly from your solver.

ORGANIZE BY SITUATION
Group your ranges into folders by position, stack depth, or any system that works for you. Some standard 6-max 100bb ranges come pre-loaded so you can start right away.

QUIZ YOURSELF
Two revision modes test your memory:
• Hand-by-hand: see a random hand, pick the correct action
• Full grid: rebuild an entire range from scratch

Track your accuracy and focus on the spots you get wrong.

PREFLOP SOLVER
Run push/fold calculations against common opponent ranges. See the EV of shoving vs. folding for any hand at any stack depth.

FEATURES
• Full 13x13 hand matrix editor
• Raise, call, fold, and custom actions
• Mixed strategy support (e.g. 60% raise / 40% call)
• Clipboard import/export (range string format)
• Folder organization
• Hand-by-hand and full-grid revision modes
• Built-in push/fold solver
• Pre-loaded 6-max opening ranges
• Works offline — all data stays on your device

Free to use. No account required.
