Intuition Check is a simple app for testing and training your intuition.
Try to sense the hidden value — a playing card, a number, or a picture — before it's revealed. Two modes let you practice in different ways:
• Passive intuition — the hidden value is already chosen. Read it before you flip.
• Active intuition — the hidden value isn't set yet. Will it into being, then check.
Features
• Guess with playing cards (36- or 52-card decks), with numbers (adjustable digit range), or with image sets — choose a ready-made set or build your own from your photos, added from your photo library, camera, or files
• Three play styles: reveal one value at a time; lay the set out as a grid and tap to find the hidden value — a correct tap lights up green; or, in active mode, draw a whole series of random values and score it against the one you willed
• Ready-made sets: add a finished image set in one tap — Zener Cards, Shapes, Colors and Rock Paper Scissors are free; the Zodiac Signs set is a one-time purchase
• Keep several guess sets side by side, each with its own settings, and switch between them right in the main view
• Track your results: mark each round correct or wrong — or enter your guess before revealing and let the app score it, telling you straight away whether you were right
• Note your state during rounds — rested or tired, calm or stressed, sure or in doubt, after coffee or after exercise — and see in the statistics whether it makes a difference. The built-in states are a starting point: rename them, add your own, or switch off what you don't need
• See how often you're right compared to pure chance, your best streaks and the state they happened in, and how you do by state and by time of day — and, if you choose to save statistics on your device, how you're doing over time
• Share image sets with friends as files, or send them straight to your partner's phone in partner mode
• One-tap reveal for quick rounds
• Clear view mode hides the toolbar and pickers for a distraction-free session — touch and hold to exit
• Partner mode connects two phones directly over your local network for shared sessions — with cards, numbers, and your image sets
Private by design
Intuition Check collects nothing. No accounts, no analytics, no telemetry, no third-party SDKs. Your settings, photos and results stay on your device, and partner mode talks phone-to-phone over your local network — nothing is sent to us, and we run no servers that could receive it.
Try it free
1 hour of free in-app time — it counts only while the app is open on screen and adds up across your sessions. If it runs out before you've decided, the subscription screen lets you reset it for another hour, up to 3 times. To keep going, subscribe monthly or yearly: $0.99/month or $9.99/year (shown in your local currency), auto-renewing every month or every year until you cancel. Family Sharing–enabled, for up to five family members. Cancel anytime in Settings → Apple Account → Subscriptions. Subscriptions with additional features may be added in the future; everything this one includes stays included.
Ready-made sets
Some sets are free, others are a one-time purchase (shown in your local currency) and Family Sharing–enabled. They're separate from the subscription: buying a set doesn't include app time, and subscribing doesn't include the paid sets. Anything you add becomes your own copy — rename it, reorder it, remove pictures, or share it with a partner.

The app's website has a step-by-step how-to guide and a questions-and-answers page — guess sets, your own photos, partner mode, statistics and more. Both are linked in the app under Settings → About.
