About this app

There is a signal you may have felt before. The card you knew before it turned. The friend who texted the moment you thought of them. The bad feeling about a person or place before you knew why. The dream about the thing that then happened. Everybody has a story like that. Almost nobody has a score. Most people learn to laugh it off. A few learn to harness it. PSI is the Program built to make a sixth sense as ordinary as the other five, and the door is now open to you. PSI is a card game for testing your intuition. Each card is drawn with cryptographic randomness and locked in code before you call it. Every hit and miss goes on a record you can't edit, and your score is measured against chance. HOW YOU PLAY The app draws a card, hides it, and waits for your call. The card flips, and your hit or miss goes on the record. One good run is luck. A hundred is something else, and a record kept over months is where the truth shows up: whether you're tapped in or just lucky. Through the door is the Program. Its codename is FIRST LIGHT, the name astronomers give the moment a new instrument first sees, and here the instrument is you. You're inducted on a phosphor-green terminal, given a codename, and a contact on the inside called FIREFLY. Beyond the terminal is the Field. It has always been there, in every room you've ever sat in, invisible to the five senses you were told were the limit. Every faint intuitive signal you've ever had came from it. Inside the Program you'll learn how this sense was turned down in all of us: dozens of receptors behind it, in everyone, powered down and forgotten. Your job is to turn the light back up. KEY FEATURES FIRST SIGHT. Five symbols, one call. Circle, cross, waves, square, star: the deck Karl Zener drew for J. B. Rhine's Duke lab in the 1930s. Chance is 1 in 5. Beat it and the room goes quiet. NIGHT GLASS. A real 52-card deck, and you choose how far to go. Red or black is 1 in 2. Suit is 1 in 4. Rank is 1 in 13. Name the whole card and it's 1 in 52. The odds get long. The hits get loud. SIGNAL INDEX. One number for whether you're above chance: your last 100 calls per deck, misses included, passes left out. It can go up. It can go down. It only ever tells the truth. SOLO RUNS. No partner, no shuffling, no setup. Run 12 or 24 calls, or Survival on 5 lives. The deck resets after every card, so every call is a fresh deal at the same odds. PARTY MODE. Round Robin: 2 to 8 friends, one phone. A hit keeps the phone and builds your streak. A miss passes it on. By the third hit nobody's laughing. Party games stay out of your personal stats. ESP LEAGUE. A record book for a sense nobody was keeping score on. Post your best run under a codename. Climb the monthly board, or set a global record in the Hall of Fame. LEARN THE METHOD. 21 short modules on the skill behind the call: how to settle, how a signal shows up, how to tell it from a guess. A hundred-year paper trail behind them, from the Duke lab to the declassified files. START FOR FREE No account. The first 14 days give full access; after that, the free allowance is 3 sessions a day.
