Intuition Check.

You might do differently just after waking, late at night before sleep, rested or tired, calm or stressed. Note your state in the main view as you play, and the statistics compare your rounds by state and by time of day — so you can see whether there's a pattern for you.

Feeling sure of yourself, or full of self-doubt, could line up with how you score. Confidence is one of the states you can note before a round, so it's one more thing to watch for as your rounds add up.

Landing right noticeably less often than random guessing would predict is also a departure from chance — one reading is that intuition is working against you in that moment, rather than that nothing is happening.

Two modes. In passive, the value is chosen before you look — try to read it. In active, nothing is chosen until you reveal — try to will it into being. Tap to reveal.

Two iPhones find each other automatically. The same Wi-Fi network gives the steadiest link at any range; with no shared network, keep the phones close and they connect directly. One person picks, the other guesses. No accounts, no servers.

Choose 36- or 52-card decks (jokers optional). Numbers from a single digit up to 9 digits — 1 to 999,999,999. Keep several guess sets side by side, each with its own settings.

Build guess sets from your own photos — added from your photo library, camera, or Files — and try to sense which picture is hidden.

Mark each round correct or wrong — or enter your guess before the reveal — and see how often you're right compared to pure chance, your best streaks, and trends over time.

Send an image set straight to your partner's phone during a partner game, or export it as a file and share it by AirDrop, Messages, or Mail.

Instead of one value at a time, see the whole set as a grid and tap to find the hidden one. Each tap is its own round; a correct tap lights up green. Works with cards, numbers and images.

In active mode, will one value and let a single tap draw a whole series of random values — from 2 to 10 million — scored against it. Set the length on the main view and the pace in Settings; each series goes into your statistics as one entry.

A correct guess can flash green and buzz — a quick, satisfying signal that you were right, with no extra taps. Turn either on or off.

Hide every control for a calm, distraction-free session — just you and the reveal. Touch and hold anywhere to bring the controls back.

See how many rounds you have played and how you are doing right on the main view — one count and result per mode and play style, with a reset button. Turn on Save round counts and results in Settings → Statistics to keep them between launches.

Every feature added in recent versions has its own switch in Settings → Features. Switched off, it disappears from the main view, Settings and the statistics filters — nothing you recorded is deleted.

Your accuracy shown next to the baseline a random guesser would score for that pool — so “30%” means something, whether the odds were 1 in 3 or 1 in 52.

A plain-language verdict — from “consistent with chance” to “far above chance” — with the rarity spelled out: a result this strong happens about 1 in X times by luck alone.

Your longest runs of consecutive hits, each with the day and time it happened and the state you had noted during it. You decide how long a pause is allowed before a streak counts as broken.

A day-by-day hit-rate chart, so you can see whether you are actually improving — or just remembering your good days. A separate breakdown by time of day shows when you tend to do best.

Passive (reading a value already chosen) and active (willing one into being) are scored separately, so you can tell which one you are better at.

Which values come up most, which you tend to pick, and how often each guess is right — enough to spot the patterns and blind spots you did not know you had.
