One circle of five: you plus four friends. The real, working experiment.
Available nowYou thought about them. They rang.
Spanda: the guess-who's-calling game for close friends.
Spanda is a free telephone-telepathy test for you and four close friends. Each round, one of you is secretly chosen to call; the receiver locks one guess (out of four) before the reveal, and a right guess makes a phone actually ring. Chance says 25%; we keep honest score to see if your circle beats it. Telepathy stays a hypothesis under test, never a claim. It works in your browser and installs on iPhone and Android like any app.
Five friends. Magic-link sign-up. No card. No belief required.

You know the feeling
Ever been thinking about a friend, and they call?
You picture someone, and seconds later they text. You reach for your phone to call them, and they’re already ringing you. You turn a corner and bump into the exact person who was on your mind.
Everyone has these spooky little moments. But is it just chance, or a knack you can actually get better at? Do you and one particular friend have a real talent for it?
Nobody’s ever bothered to keep score. So why not find out with your friends?
Start a circle, invite the four people you’re closest to, and turn those little moments into a shared experiment, and maybe a deeper connection along the way.

Spanda · the pulse before the ring
The product is simple: a game that tests whether you can tell which friend is calling.
Spanda is a Sanskrit word often translated as a subtle pulse, vibration, throb, or movement of life. We chose it because this game is about tiny felt signals: not grand claims, not thunderbolts.
The small pulse before the phone lights up. The name that arrives before the notification. The sense that someone is near in attention before they appear on the screen.
We’re not asking you to believe a doctrine, just to notice, play, guess, record, and see.
One ping. One guess. One reveal.
A tiny experiment hiding inside a very good game.
Groups of five: you and four close friends. Every round puts the odds on the table.
- 01
A trial forms
Your circle gets the same nudge at the same time. One friend answers, and the trial is on.
- 02
One caller is sealed
Spanda secretly picks one caller using a cryptographic random draw. Nobody gets to steer the result.
- 03
You lock your guess
The countdown ends. Choose one of four friends before anything is revealed. Guess right and your phone actually rings.

The science · hypotheses under test
Spanda is a free web app for small groups of five close friends. In each round, one friend is randomly selected as the secret caller; the receiver locks a single guess at who it is before a timed reveal. A correct guess can trigger a real phone call. Spanda frames telephone telepathy as a hypothesis under test, not a proven ability. With four possible callers, chance predicts a 25% hit rate.
Curious, careful, and allergic to pretending.
Spanda is a playful, opt-in experiment inspired by telephone-telepathy research, without claiming telepathy is proven.
With four possible callers, chance predicts a 25% hit rate. Sheldrake & Smart reported roughly 40% in their 2003 telephone study and 45% in videotaped trials. Those findings are research inspiration, not an endorsement, partnership, or settled conclusion.
The wider scientific consensus remains that telepathy has not been established.
Even an above-chance score may reflect luck, habits, shared routines, selection effects, or other ordinary explanations. Spanda generates hypotheses and structured observations; it does not prove a mechanism.
Built so nobody can cheat, including us
Nobody, not even us, can change who was picked after you guess. Here’s the machinery:
- 1Crypto-random caller selection
- 2Sealed hash commitment before the trial
- 3Guess locked before the reveal
- 4Visible chance baseline for every trial
- 5Tamper-evident result log, exportable on request
Research inspiration: Rupert Sheldrake & Pamela Smart (2003). Spanda is independent and makes no claim of their endorsement.
The Mark
Two arcs. One signal. A gap that matters.
The arcs reach toward each other, but never close. The dot is the moment of attention between them.
Connection is not possession.
Intuition is not certainty.
A hit is not a verdict.

Straight answers. No mystic sales pitch.
Are you saying telepathy is real?＋
No. Telepathy is a hypothesis under test, not a proven explanation. A high score can have many causes, and the wider scientific consensus remains that telepathy has not been established.
Can Spanda tell me who I should trust?＋
No. Spanda is a game and an opt-in experiment, not a clinical, therapeutic, relationship, or decision-making tool.
What happens when I miss?＋
The miss is recorded exactly like the hit. No shame, no selective memory, no disappearing inconvenient results. A miss is still data.
Can anybody rig a trial?＋
Nobody, not even us, can change who was picked after you guess. The caller is chosen by a cryptographic random draw and sealed with a hash commitment before the trial, your guess locks before the reveal, and every outcome goes into a tamper-evident log (your data is exportable on request).
Why five people?＋
In a full circle of five, the receiver guesses among the other four, so each guess has a clear 25% chance baseline. It also follows the small-circle format that inspired the experiment.
Does it cost anything?＋
The circle-of-five path is free and working now. Every paid option shown below is a preview only: coming soon, with no payment taken yet.
