Bankroll is the pre-session workout for serious blackjack players. Whether you're starting your first basic-strategy chart or tightening your edge for a real-money trip, Bankroll gives you the cleanest training surface on the App Store. No banner ads. No gambling-cliché chrome. No upsells in the middle of a session. Just the work. WHAT'S INSIDE • Quick Hand — drilled 1-on-1 hands with instant feedback. The fastest way to find your weakest cells. • Free Play — open-ended hands. Hit, stand, double, split, surrender — full action set. Every decision logged. • Full Shoe — six-deck shoe with the cut card. Always-on running count, true count, bet ramp, and composite scoring at the end of the shoe. • Strategy Drills — laser-focus on a specific scope: pairs, soft hands, hard 12–16. The drill targets the cells you've been getting wrong. • Stats — every decision is recorded. See your basic-strategy accuracy heatmap, your weakest cells, and your trend over time. THREE HINT MODES • Casino — no hints. Real reps. The number you'd get at a real table. • Coached — peek-on-tap. Half-credit if you peeked. • Trainer — always shows the play. Half-credit per rep. Casino accuracy is the real number. Practice accuracy rolls up Trainer + Coached reps with the half-credit weighting so you can't launder hints into your headline number. FIVE COUNTING SYSTEMS Hi-Lo, KO, Hi-Opt I, Hi-Opt II, and Halves. Per-system bet ramps. Side-count placeholders for Aces if you're working through Hi-Opt II. INDEX PLAYS Illustrious 18 plus the Fab 4 surrender plays surface in context when the count crosses the index, so you train deviations in the same surface where you'd execute them. OFFLINE BY DEFAULT Every decision, session, and stat is stored locally on your device. No accounts. No cloud sync. Nothing leaves your phone. Built by an AP for APs. The hub is a cockpit, not a casino lobby. The math is honest. The chrome is restrained. If you're serious about getting an edge, this is the practice surface you've been wanting.
