Seal a hunch before the event.
Log an impression before it happens, seal what would confirm it, record how likely it was anyway, and name the channel it arrived through. Then resolve later and let the math, not your memory, tell you which of your channels actually land. You don't have to guess. You can see what's happening.
Maybe it's noise. Maybe it isn't. This is how you'd actually find out.
What it measures
Rangefinder is a precognitive impression journal. It doesn't know whether precognition is real. Neither do we, and that's exactly why it's worth measuring, honestly, for you. It checks one thing: does what you wrote before the event match what happened after? It's scored against how likely the impression was anyway, so a lucky call on an obvious thing earns nothing, and an honest long shot that lands means something.
How an entry works
- The impressionWrite it exactly as it arrived: a dream fragment, a flash, a feeling. Don't clean it up.
- Make it checkableSeal the confirmation, the thing that would count as a yes, and a check-by deadline.
- How likely, honestly?How likely was this anyway? An honest 10% makes a later yes interesting; a 90% hit proves nothing.
- The channelPick one, locked the moment you log it: dream · edge-of-sleep · waking flash · meditation · synchronicity.
Later, resolve each entry: hitpartialmissvoid
Why both halves are sealed
Precognition's one adversary is memory rewriting itself. So both the impression and its confirmation are locked in advance, before the outcome exists.
If you could edit either after the outcome, a hit would prove nothing. You'd just narrow the criterion to fit. The channel is locked the moment you log it, so you can't later re-attribute a lucky hit to a different channel.
How the score is made
Your own hit / partial / miss call is the only input to every number. From your record, Rangefinder builds:
- Lift is how much your outcomes beat what you thought was likely, in points. The number no belief-app will show you.
- How honest your confidence was across all your calls, in one number. (A Brier score, where 0.25 is coin-flipping.)
- Where you're off: a plain-language read that names where your confidence and your results drift apart. (A calibration read.)
- The Channels scoreboard shows each channel's hit rate against every other, only once both sides have enough data. It's a pattern, not proof. If something's really there you'd expect an edge in some channels; if it's noise you'd expect flat rates. The scoreboard just shows you which.
The AI only weighs in after the fact
Once you resolve an entry, an optional on-device helper reads what you sealed against what happened and gives its own take on the overlap. It can never turn a miss into a hit.
It never touches your numbers. Your own call is the only input to every stat, and nothing you write leaves your phone. Pro, advisory, on supported iPhones.
