Blackjack Copilot

The Hi-Lo card counting assistant for learning Blackjack ! Log cards, get real-time true count, informations on deviations and smart bet sizing, all in your pocket.

Blackjack Copilot is a professional-grade Hi-Lo card counting assistant built for serious blackjack players. Designed for speed and clarity, it keeps your running count, true count, and play decisions always one glance away. If you're training to understand more than basic strategy and want to upgrade your game, you have a new copilot !

COUNTING Enter each card with a single tap — LOW (2–6), NEUTRAL (7–9), HIGH (10–K), or ACE. The running count and true count update instantly. An ace side count with Stanford Wong surplus calculation helps you track every edge.

PLAY DEVIATIONS Blackjack Copilot covers the full Illustrious 18 (Don Schlesinger) and all Fab 4 surrender deviations. Deviation thresholds are deck-specific — separate index tables for 1, 2, and 4/6/8 deck shoes. When the count calls for a strategy change, the deviations panel lights up immediately so you never miss a key play.

BET SIZING A 5-level bet ramp guides your sizing from 1× to 12× based on the true count, with an edge estimate at each level. The ramp is calibrated conservatively relative to full Kelly to limit risk of ruin.

SHOE TRACKING A color-coded TC sparkline charts the true count over time. A penetration bar tracks shoe depth with a configurable shuffle alert (65–80%). The round delta tracker records your running count change and cards seen per round so you can spot trends across the shoe.

FAST INPUT Four large buttons are pinned at the bottom of the screen for one-thumb entry. Optional swipe gestures over the top section of the UI let you log cards without looking at the screen. A 25-step undo buffer and a confirmation-protected shoe reset keep mistakes from costing you.

SETTINGS Choose 1, 2, 4, 6, or 8 decks. Toggle between S17 and H17 dealer rules. Switch between dark and light mode. All settings are saved automatically between sessions.

BILINGUAL Full English and French interface. The app detects your device language automatically and switches accordingly. An in-app user manual is available in both languages.

Blackjack Copilot is a tool for players who already know basic strategy and want to take their game further. It does not teach card counting from scratch but it sure helps play better !
