Built for the table, not the classroom

Know the shoe.
Play the numbers, not the hunch.

Hidden Ace turns your phone into a silent analyst. Tap or swipe to log every card as it's dealt, and get a true count, shoe composition, and a statistically derived recommendation for every decision — without ever pulling up an app screen at the table.

How it works

Four taps between you and the right play.

Hidden Ace was built around one constraint: nobody can stare at a phone at a blackjack table. So the entire input layer runs on gesture and vibration — the analysis happens in the background, the whole time.

01

Watch the deal

Set your number of decks, penetration, and table rules once. Then just watch the cards land like you normally would.

02

Log with a gesture

A tap or swipe in your pocket logs each card via iOS Shortcuts — no screen, no glance, nothing a pit boss could ever notice.

03

Count updates instantly

Running count, true count, and full shoe composition recalculate the instant a card lands — Hi-Lo under the hood, decks-remaining aware.

04

Get the play

A Monte Carlo simulation runs against the current shoe and returns the statistically best action and bet size for the hand in front of you.

Gesture-based card entry

Input that never breaks your cover.

Every gesture maps to a specific card value and triggers a distinct haptic pattern through iOS Shortcuts, so you can confirm what you logged without looking down.

Single tap

Logs a low card (2–6) — the count-positive group — with one short pulse.

Double tap

Logs a neutral card (7–9) with two quick pulses — no count impact, full composition tracking.

Swipe

Logs a high card (10/face/Ace) — the count-negative group — with a long pulse.

Hold

Undo the last card logged — for the misdeal, the renege, the moment you miscounted.

What's actually running under the hood

Not a cheat sheet. A live simulation.

Hidden Ace doesn't look anything up in a static strategy chart. Every recommendation is computed fresh, against the actual composition of the actual shoe in front of you, the moment you need it.

Real-time true count, the right way

Running count divides by decks remaining — not decks dealt — recalculated after every single card, including mid-shoe shuffles, burns, and cuts you tell it about.

  • Hi-Lo running count updated card-by-card
  • True count = running count ÷ decks remaining
  • Configurable deck count and penetration per table
Running count
+14
Decks remaining
4.4
True count
+3.2
Penetration

Shoe composition, card by card

Beyond the single true-count number, Hidden Ace tracks exactly how many of each rank remain in the shoe — the input every probability calculation downstream actually depends on.

  • Per-rank depletion tracked across the full shoe
  • Ten-rich and ace-rich shoes flagged automatically
  • Drives every downstream EV and bet-sizing calculation

Statistically derived recommendations

Every hand runs a Monte Carlo simulation against the live shoe composition — thousands of simulated outcomes for hit, stand, double, split, and surrender — and returns whichever action carries the highest expected value right now, not what a generic basic-strategy chart says for an infinite deck.

  • Hit, stand, double, split, and surrender all scored by EV
  • Simulation re-run against the count, not a static chart
  • Accounts for your table's specific rule variations
HIT
EV −12%
STAND
EV +4%
DOUBLE
EV +18%
SPLIT

SURRENDER

Kelly-based bet sizing

Your edge changes hand to hand as the shoe depletes. Hidden Ace converts the current true count into a recommended bet spread using the Kelly criterion, so your bet size always tracks your actual statistical edge instead of a gut feeling.

  • Bet spread scales with true count, not flat units
  • Configurable bankroll and risk tolerance
  • Designed to avoid bet patterns that draw attention

What players are saying.

★★★★★

"I stopped second-guessing doubles. The count is just always right there, in my pocket, and the recommendation matches what the math says — not what I feel like doing."

"The gesture input is the whole point. I tried two other counting apps before this one and both needed me looking at a screen at the table. This one doesn't."

"Bet sizing was always the part I winged. Seeing it tied to true count and an actual Kelly calculation changed how I think about ramping up."

Questions

Frequently asked questions.

Card counting itself is legal everywhere in the sense that no law prohibits doing math in your head. Casinos can, and sometimes do, ask a suspected counter to leave or stop playing blackjack — that's a private property decision, not a legal one. Hidden Ace doesn't change that risk; it just makes the counting itself effortless and invisible, since all input happens through gesture and vibration rather than a visible screen.
The gesture-input layer is built on iOS Shortcuts, so the fully hands-free experience is iPhone-specific today. The web app itself works in any modern mobile browser if you'd rather tap directly on screen, though that obviously loses the "no screen at the table" advantage.
Like any counting system, Hidden Ace's accuracy depends on every dealt card actually being logged. A hold gesture lets you undo the last card immediately if you mislog one, and the documentation covers recovery techniques for missed cards mid-shoe.
Hidden Ace uses the Hi-Lo system for the running and true count, converted into decks-remaining-adjusted figures. Recommendations themselves go a layer deeper than a count-based chart lookup: each decision runs a fresh Monte Carlo simulation against the shoe's actual current composition.
