The blackjack card counting app for serious players. Track the count, get bet recommendations, and master deviations — all from your phone.
Built for counters
Heater is designed for players who already understand blackjack and want a tool that keeps up with them. Clean interface, fast tap targets, and no-bullshit accurate math.
Hi-Lo with side bets
Standard Hi-Lo running and true count, plus dedicated counters for Lucky Ladies, Perfect Pairs, and 21+3 with full suit tracking.
Bet sizing on the fly
Kelly-based recommendations from your bankroll, with override options for casual players. Spread automatically scales with the count.
Two modes
Simple mode for fast home practice. Table mode simulates a real shoe with seats, hands, and live deal flow.
Complete strategy
Full basic strategy chart — hard totals, soft totals, pair splits, surrender — plus the Illustrious 18 deviations.
Session tracking
Log sessions across devices. Optional win/loss entry. See your lifetime stats and longest heaters.
Privacy first
No tracking, no ads, no third-party analytics. Your data stays yours.
Free or Pro
Free tier gives you 50 cards per day with full feature access — enough to test it at the kitchen table or run a quick session. Pro removes the limit and unlocks everything for $9.99/month or $79.99/year.
Heater is an educational and analytical tool. Card counting is not illegal in most places, but casinos can refuse service, ban players, or void winnings online. Using a phone or device at a live blackjack table is prohibited in many jurisdictions, including Nevada under NRS 465.075. You are responsible for knowing the laws and venue rules where you play. 18+ only.
Coming soon
Heater is in active development. The app launches on the App Store and Google Play in 2026. For early access, beta invites, or partnership inquiries, reach out via the support page.
