Blackjack Trainer: 21 Coach

Blackjack Trainer teaches you the mathematically correct way to play blackjack, one hand at a time. Every recommendation in this app is basic strategy: the provably optimal play for every hand, verified against a reference expected-value engine, not gut feel or folklore. Play practice hands at a first-person table with a dealer, get instant feedback the moment you act, and learn exactly why a play is right or wrong in plain English. NEW IN 1.2 - Daily challenge: the same ten hands for everyone, one attempt a day, with a result to share - Day streak with a daily goal and one free rest day a week - A 14-day path through every lesson and drill - Share your streak and progress as a card to Instagram, TikTok, and more - Optional practice reminders, off until you turn them on - Cards dealt one at a time in real dealer order, with animated hand signals WHY BASIC STRATEGY Basic strategy is the set of mathematically optimal decisions for every blackjack hand, worked out through exhaustive computer analysis of the game's probabilities. Playing it perfectly doesn't guarantee any single hand goes your way, but it is the mathematically strongest way to play, every single hand. This app exists to help that strategy become second nature, through repetition and clear explanations, so you can play with confidence. RULE-AWARE, NOT ONE-SIZE-FITS-ALL Correct blackjack strategy changes with the table rules, and this app adapts to match: - Dealer hits or stands on soft 17 (H17 / S17) - 1, 2, 4, 6, or 8 deck shoes Change either one in Settings and every recommendation updates to match, because the correct play for a 16 against a dealer's 10 is not the same at every table. The charts assume double after split and late surrender are allowed. LEARN BY PLAYING - A living practice table with a dealer, a real deck of cards, and subtle table motion that makes practice feel real - Instant feedback after every decision, with a plain-English explanation of why a play is correct or incorrect - Short "Remember" mnemonic cards that reinforce the pattern behind a decision, not just the answer - A full basic strategy Chart tab you can flip through any time, color-coded and organized by hard totals, soft totals, and pairs - A Learn tab with lessons and drill packs targeted at your weakest spots, built from your own mistakes and lowest-mastery cells - A Progress tab with an accuracy ring, a day streak, a trend sparkline, and a mastery heatmap across every hand and dealer upcard COUNT: HI-LO SKILL TRAINING The Count tab trains the Hi-Lo running count and the true count on cards the app deals. Learn how each card is tagged, how to keep a running count, and how to convert it to a true count, then see how the count behaves at single deck, double deck, and shoe tables. Three drills: card by card, a timed deck countdown, and true count conversion. It is a practice drill only, with no card entry from a live table. SPEED MATH Add up a hand before the clock runs out. Two modes, Total and Make 21, a timer you can set to 3, 5, or 10 seconds or turn off, and an ace that counts as 1 or 11. Fast, accurate arithmetic is the foundation for everything else. 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, exactly the way a chess tactics trainer grades moves. PRIVATE BY DESIGN Blackjack Trainer works completely offline. There's no account, no sign-up, and no internet connection required. Your progress is stored only on your device. There are no ads, no in-app purchases, no analytics, and no third-party tracking of any kind. Whether you're brushing up before a friendly game, getting ready for a trip, or just curious what the "correct" play actually is, Blackjack Trainer turns basic strategy from a chart you memorize into a skill you actually build.
