Roulette Stat Master

Roulette Stat Master is a statistics tool for the European single-zero wheel. You record the spins; it does the counting, the distribution maths and the comparison.

IMPORTANT: This is not a gambling app, not a betting app and not a real-money game. It takes no money, deposits, bets, wagers or withdrawals, and pays no cash prizes, credits or rewards. It has no influence over a real wheel.

Tap a number and the spin is recorded. Sector Radar opens outside study at 7 spins and numbers at 20; the five-signal engine holds numbers to 37, a full turn of the wheel. Every analysis engine runs on your device.

THREE WAYS TO READ A SESSION

• Sector Radar: reads how far the ball travels around the wheel between spins, not how often each number lands. Outside calls from spin 7, nine pockets from spin 20, plus a meter for how far this session sits from fair.
• Internal AI: the built-in signal engine, five views of one session at once.
• Red/Black Rule: names red or black by a fixed pattern - switch after a hit, switch after a first miss, repeat after a second. The odds never change; every spin stays 48.6%.

Mode Performance scores every mode's red/black calls against the 48.6% line chance alone produces.

TRACK AND STUDY EVERY SPIN

• One-tap spin entry on a real casino table layout
• Live statistics that update spin by spin
• Most and least frequent numbers, with the count for each
• Color, odd/even, low/high, dozens and columns distributions
• Current color and parity streaks
• True European wheel pocket order throughout
• Session history, saved as you go
• JSON export through the share sheet

THE FIVE-SIGNAL ENGINE

Five views of one session, ranked by which matches your recorded distribution most closely. For comparison and learning, never as advice.

• Recent Bias: recency-weighted frequency analysis
• Context Bias: repeated tail-pattern matching
• Rhythm Bias: streak and alternation study
• Gap Bias: return-gap and overdue-number study
• Wheel Signals: wheel-sector and alignment study

BUILT FOR EVERYDAY STUDY

• iPhone and iPad, portrait and landscape
• Dark, light and system themes
• 14 languages
• No account, no sign-in, no ads

PRIVACY

• Every analysis engine runs on your device. The spins you record are never sent to any third-party AI service, and leave the device only when you export them.
• The app does talk to the App Store for subscriptions, to our own server for the free daily allowance and purchase checks, and to Firebase for crash and usage diagnostics.
• A new install checks in with that server once to activate its allowance, so the first study output needs a connection. The analysis itself never does.

FREE AND PREMIUM

Free use gives you 50 analyses on your install day and 25 a day after that, with no account. Premium removes that daily cap. Every study mode, every signal and the Analytics screen are available to everyone, free.

• Premium Monthly: one month, auto-renewing
• Premium Yearly: one year, auto-renewing

Prices vary by country and are shown in your own currency before you confirm.

Payment is charged to your Apple Account at confirmation of purchase. A subscription renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period, and your account is charged for the renewal within 24 hours before the period ends. Manage or cancel in your Apple Account settings after purchase.

DISCLAIMER

Roulette outcomes are statistically independent on a fair wheel. Every signal or probability output is a mathematical study estimate - not betting advice, not a winning method and not a guarantee. Past frequencies do not predict future spins. For education, statistics, simulation, research and backtesting by adults 18+. You are responsible for the laws where you live.

New: Sector Radar, now the default mode.

It reads how far the ball travels around the wheel between spins, instead of counting how often each number lands. Outside calls open at 7 spins and the nine-pocket zone at 20, with a lock meter showing how far this session sits from a fair wheel. On a fair wheel that meter stays low, and it is meant to.

Also in this version:

• Called pockets are much easier to see. The highlight now brightens the whole tile rather than drawing a thin outline around it.
• Number tiles stay properly tappable on small screens, and the table no longer overflows at large accessibility text sizes.
• Mode Performance opens smoothly on long session histories.
• Subscription checks are steadier. A store outage or a dropped connection no longer drops a subscriber to the free tier, and the app now says what it is waiting for instead of going quiet.

Wheel Check has been removed. Sector Radar reads the same sessions and has something to say far earlier.
