Rangefinder: Precognition Log

Rangefinder is a precognitive impression journal — for logging what arrives before you know how things turn out, and finding out, honestly, whether any of it holds up. Write down the dream, the flash, the feeling — before the event, not after. Seal it with a confirmation (what would count as it happening) and a check-by date. Say how likely it seemed anyway, setting the impression aside. When the date arrives, mark it hit, partial, didn't happen, or void. Your channel scoreboard does the rest. OUR STANCE Maybe it's noise. Maybe it isn't. This is how you'd actually find out. Rangefinder provides no readings and makes no predictions of its own — every impression is yours, written in your own words, scored against your own stated baseline. THE HONEST LOOP 1. LOG IT — a dream fragment, a hypnagogic flash, a waking jolt, a meditation image, a synchronicity too pointed to ignore. Exactly as it came, before you know how it turns out. 2. SEAL IT — a confirmation (what would count as this happening) and a check-by date, both locked the moment you save. No rewriting history once you know the outcome. 3. HONEST PRIOR — before doing anything else, say how likely this seemed anyway, 1-99%. A 90% hit proves nothing; a 10% hit is interesting. 4. TAG THE CHANNEL — dream, edge of sleep, waking flash, meditation, or synchronicity. Optional, but it's what turns a raw hit rate into "which channel is actually worth trusting." 5. RESOLVE — on check-by day, say what happened: it happened, partially, it didn't, or void it if it's genuinely unanswerable. 6. SCORECARD — hit rate, lift over your own stated priors, a Brier score, a calibration curve, and a channel-by-channel breakdown. Every stat sits behind a minimum sample size before it renders — lift needs 10 resolutions, the calibration curve needs 20, a channel comparison needs 5 on each side. Below the gate you see an unlock ladder, never a chart dressed up as proof. Partial outcomes count halfway toward your Brier score and are never silently rounded into a win. FREE TO START Logging is free forever. Your first 10 scored resolutions come with the full scorecard, unlocking each stat as it clears its own sample-size gate. After that, Rangefinder Pro keeps the advanced scorecard running, plus CSV export and import. Rangefinder Pro is $5.99/month, $39.99/year with 1 month free, or a one-time $99.99 lifetime purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the current period ends. PRIVATE BY ARCHITECTURE No account. No analytics. No server. Every impression, prior, channel tag, and resolution lives only on your iPhone. Nothing you write ever leaves your device. A NOTE ON WHAT THIS ISN'T Rangefinder doesn't claim precognition is real, and it provides no readings, forecasts, or fortune-telling of any kind. It's a journaling and self-assessment tool: you decide what you write, say how likely it seemed, and find out — from your own resolved history — whether any of it holds up.
