PSI: ESP Training

No. It's training. No session passes or fails you. Each one ends with a score, like 12 calls, 3 above chance, and the score goes on your record.

No. Nothing in the app asks what you believe, before your call or after it. You call, the card flips, the record keeps score, and the number is yours either way.

As long as you take. A session is 12 or 24 calls, or Survival, which runs until your fifth miss. There's no clock on a call. The only timer in the game is the 1.2 seconds you get to undo one.

The card is drawn with cryptographic randomness and locked in code before you see anything, and your call is stamped at the tap. Each round is chained to the one before it, so a card changed after the fact breaks the chain. Every stat is rebuilt from that chain.

The deck has no opinion of you. It can't flatter you or punish you. Each card comes from the phone's secure random generator and is sealed before your call, and the draw never reads your record.

Not much you'd want. Sessions are a fixed length. The deck resets after every card, so there's nothing to count, and the Signal Index only reads whole runs. You can walk out of a run, and a run you quit doesn't count, whether you were ahead or behind.

Better than chance, over 100 calls. On the 5-symbol deck, chance is 20 hits in 100. The Signal Index reads your last 100 calls per deck, misses in, passes out, and only finished solo runs count. It shows a provisional number from 20 calls and settles at 100. It can go down.

It means you had a bad run, which is what chance looks like most nights. On this deck the odds miss 4 calls in 5. The miss goes on the record next to the hits, and the Index reads your last 100 calls, not one night. If nothing comes on a card, pass; a pass never counts against you. Then you go again.

For the evening, yes. For the record, not yet. Five straight on the 5-symbol deck comes up about once in 3,000 five-call stretches, and a long record has a lot of those. That's why the Index reads 100 calls, not 5.

No. Pass. The pass goes on the record but never counts against your hit rate, so you're never made to call blind.

Nobody can promise you a number, and PSI doesn't. It promises you'll know. The Index moves with your last 100 calls, up or down, and Learn The Method has 21 short modules on the skill behind the call: how to settle, how a signal shows up, how to tell it from a guess.

There's a method, and it's there to stop the guessing. Settle first. Notice what shows up before you reach for it. Call that, and pass when nothing comes. The modules go deeper: what a signal feels like, how to take the first impression, and why you stopped noticing.

Because a real deck can't be sealed. Someone shuffles, someone holds the target, and the odds drift as the deck runs down. PSI came out of exactly that card game: the developer got tired of shuffling and wanted a deck he could trust. Here the card is locked before you call, and the deck resets after every card.

Free, with no account and no ads. You get 14 days of full access, then 3 free sessions a day, for good. The 14 days is counted on your phone: no subscription starts, nothing is charged, and there's nothing to cancel. PSI PRO lifts the daily limit, and your score, record and stats are never behind it.

Unlimited sessions, one streak repair a month, new deck designs from the Pro collection, and the option to change your codename. US$7.99 a month or US$49.99 a year, about 40 per cent off the first period, then full price. It renews until you cancel. Your score, record and stats are never paywalled.

Your record lives on your phone. Finished runs also go to PSI's server for the League, under a random ID made at install with no name or email attached. The board shows a codename you chose. Nothing is sold or tracked, and no study is run on it. Delete My Data in Settings erases your record and codename on the phone and the server.

The history is. Washington spent $20 million over two decades, across the CIA, DIA and Army intelligence, testing whether people can sense a hidden target. It filed the answer as inconclusive and closed the program as Star Gate in 1995. The Archive in the app cites it. The Program, FIRST LIGHT and FIREFLY are the game's fiction, and PSI has no link to any agency.

No. PSI predicts nothing about your life. It shows you a card you can't see, records your call, and scores the record against chance. That's the whole instrument.

Yes. Round Robin is the party mode: 2 to 8 friends, one phone. You call, the card flips. A hit keeps the phone and builds your streak, a miss passes it on, and a tie at the top goes to sudden death. Party games stay out of your personal record. The League is global.

From 13. PSI is rated 13+: no chat, no messages, no gambling. The only thing another player ever sees is a codename on the League board, which can be reported or blocked. It was built partly for kids like the developer's cousins, so they get to test their senses before the world tells them they can't.
