About this app

Blackjack Card Counter is a practice tool for learning and applying card counting — the legal, math-based skill that shifts the odds in blackjack toward the player when the shoe holds more high cards than low.

Tap a card as it's dealt and the app tracks your running count, true count, suggested bet sizing, insurance decisions, and index-play deviations in real time — the same core engine as our desktop software, redesigned for one-handed phone use.

FREE, NO ADS
• Easy Red 7 — Arnold Snyder's unbalanced system, the easiest count to learn

• Full basic strategy chart (hard totals, soft totals, pairs)
• Built-in guide covering every strategy, term, and button

UNLOCK 21 MORE STRATEGIES — ONE-TIME PURCHASE, NO SUBSCRIPTION
Hi-Lo, Hi-Opt I & II, KO, Omega II, Wong Halves, Zen Count, the full Revere family, and more — the same 21 presets available in our desktop software, unlocked forever with a single purchase.

HOW IT WORKS
Set your deck count and bet unit, choose a strategy, then tap each card rank as it's dealt (or use +1/−1 for manual adjustments). The display shows running count, true count, a recommended insurance decision, suggested bet size, and key index-play deviations (16 vs 10, 12 vs 2, 10 vs X).

Card counting is a mental skill, not cheating, and is legal in most jurisdictions — always follow the rules of wherever you play. This is a practice and reference tool; it does not connect to any casino or game.

What’s new

Fixed the Decks and Bet Unit fields on the counter screen so they use a clear, easy-to-read entry screen instead of the keyboard hiding your input.
