Blackjack Trainer is a blackjack strategy trainer: learn the basic strategy chart for your table rules, then train Hi-Lo card counting. Every decision is graded, explained in plain English, and drilled until it sticks. Every recommendation is basic strategy, the mathematically optimal play for each hand, verified against a reference expected-value engine, not gut feel or folklore. Play practice hands at a first-person table, get instant feedback the moment you act, and learn exactly why a play is right or wrong. WHAT IS BASIC STRATEGY? Basic strategy is the set of optimal decisions for every blackjack hand: when to hit, stand, double down, split or surrender against each dealer upcard. It can't guarantee any single hand, but it is the strongest way to play, and this app makes it second nature through repetition and clear explanations. A STRATEGY CHART FOR YOUR TABLE RULES Correct strategy changes with the rules, and the app adapts: - Dealer hits or stands on soft 17 (H17 / S17) - 1, 2, 4, 6 or 8 decks - Late surrender offered or not Change any of these in Settings and every recommendation and the full chart update to match. The charts assume double after split is allowed. LEARN BY PLAYING - A living practice table with a dealer and a real deck of cards - Instant feedback on every hit, stand, double, split and surrender, with the reason in plain English - "Remember" cards that teach the pattern behind a decision, not just the answer - The full basic strategy chart (blackjack cheat sheet): hard totals, soft totals and pairs, color-coded - Lessons and drill packs built from your own mistakes and lowest-mastery hands - Progress: an accuracy ring, a trend line and a mastery heatmap across every hand and dealer upcard BUILD A HABIT - Daily: ten hands, the same for everyone, one attempt a day - A day streak that allows one rest day a week - A 14-day path through every lesson and drill pack - Your trickiest hand deals first when you return - Optional reminders, off until you turn them on - Share cards for your streak and progress HI-LO COUNT AND SPEED MATH The Count tab trains the Hi-Lo running count and the true count conversion on cards the app deals, with three drills: card by card, a timed deck countdown, and true count conversion. It is skill practice, like a chess tactics trainer, with no way to enter cards from a real table. Speed Math builds quick mental arithmetic: add up a hand before the timer runs out. EDUCATION, NOT GAMBLING This is a study tool, not a gambling app. There is no real money and no virtual currency. There are no chips, no bets, no bankroll, and no payouts: nothing is staked, and nothing is won or lost. You practice decisions and the app grades them, the way a chess tactics trainer grades moves. PRIVATE BY DESIGN Practice works offline. There's no account and no sign-up. Your progress is stored only on your device. Only an optional Pro purchase goes online, confirmed through Apple and RevenueCat under a random anonymous ID, never your name or email. There are no ads, no analytics, and no third-party tracking of any kind.
