About

Aperture

Most practice journals can only ever agree with you. Aperture is built so it can tell you nothing happened. It hides the target, seals what you recorded before you can revise it, and scores your impressions against what was actually in the photo. You don't have to wonder whether you're improving. You can look. A SESSION, STAGE BY STAGE - Cool-down: a short breathing pacer to quiet the analytic mind - Ideogram: a fast reflexive mark, then tag the basic gestalt - Sensory: colors, textures, temperatures, sounds, forms - Sketch: the spatial layout, on a full canvas - Assemble: your final impressions, before you commit - Reveal: only now does the target appear, and the scoring begin Until you commit, the target is never shown, hinted at, or inferable. You work from a meaningless reference number. YOUR GUT, KEPT SEPARATE FROM YOUR GUESSES Raw sensory impressions stay visually separate from flagged guesses (AOL: the mind's premature conclusions). Flagging a guess never costs you points. That separation is the habit the whole method is built on. SCORING YOU CANNOT FUDGE Your score is how much of what you sensed matches what was really there, judged against a fixed vocabulary set in advance rather than your memory of what you meant. It rewards accurate sensory data, not lucky label-guessing, and shows you which impressions matched and which missed. Log enough sessions and it will tell you plainly whether you are beating chance. A REFEREE, NOT AN ORACLE (SUPPORTED IPHONES) An optional AI judge reads the session you already sealed and scores it against the target. It can lower a generous score but never inflate one, and it never tells you what you will perceive next time. NOTHING LEAVES YOUR IPHONE No account, no analytics, no server of ours. Your sessions live on your device. Optional Pro sync goes only through your own private iCloud, and the judge runs on-device, so nothing you write is sent anywhere for analysis. FREE TO TRY, PROPERLY Your first 3 sessions are complete and full-featured: the whole protocol, the full target pool, real scoring. Aperture Pro then unlocks: - Unlimited sessions - The full 300+ target library - Analytics that show your results against chance - Unlimited named viewers with separate histories - Relay mode: two people, one hidden target, revealed together - Session export (JSON) Aperture Pro is $6.99/month, or $39.99/year with 1 month free, or a one-time lifetime purchase. Subscriptions renew automatically unless cancelled. Aperture builds on Controlled Remote Viewing, the six-stage protocol developed at SRI in the 1970s and the subject of declassified government research. It makes no claims about psychic ability and predicts nothing. It is a practice journal and an attention-training tool. Test yourself, collect your own data, draw your own conclusions.
