A logbook for places that feel wrong. Walk into a room that gives you that feeling. Tap once. Hold still for two seconds while the rig baselines. GhostTrail starts reading your phone's magnetometer, accelerometer, and GPS β€” for up to sixty seconds, or until you tap stop. You get a pin you can keep on your phone, or share to the World Map so other spotters can see what your phone measured. WHAT IT IS β€’ An honest sensor recorder. The readings are what the phone measured. Nothing else. β€’ A logbook with retro VHS chrome. Each capture earns a tape number, a phosphor-green status readout, and β€” for curated landmarks β€” a multi-section lore card you can export as an Instagram Story sticker. β€’ A curated map of nearly 200 places across six continents β€” locations known for the kind of stories that make people lower their voice. WHAT IT IS NOT β€’ A ghost detector. The app never interprets readings. It logs them. β€’ A microphone recorder. The permission is never requested. β€’ A tracking app. No advertising identifiers. No analytics. No third-party trackers. SIGNALS β€” THE PEEK ECONOMY Opening another spotter's public pin costs one Signal. You start with three free Signals, and every pin you publish yourself earns one back β€” no daily caps, no limits. Out of Signals? Publish your own pins, or buy a Signal pack from Profile β†’ SIGNALS. Three pack sizes: 3, 12 (+25% bonus), or 30 (+40% bonus). PRIVACY BY DEFAULT β€’ Captures stay on your phone by default. Nothing leaves the device until you tap SHARE TO WORLD MAP. β€’ Shared coordinates are fuzzed by Β±30 meters before upload. Precise location never leaves the device. β€’ Sign in with Apple is the only auth method. Apple's private email relay is supported. β€’ Profile β†’ Delete account permanently removes everything you have shared. FOUR TIERS OF ANOMALY Quiet Β· Stir Β· Pulse Β· Surge. The same readings, four amplifications of chrome. Your screen reacts to what the rig is seeing. A haptic pulse fires on every tier crossing. No sound is ever played. DESIGNED FOR LATE-NIGHT USE Phosphor green on near-black. Retro VHS scanlines. Monospace timecode. The interface stays out of the way. REQUIREMENTS β€’ iPhone running iOS 17 or later β€’ Magnetometer (every modern iPhone has one) β€’ Location and motion permissions, granted on first capture β€’ Camera permission optional β€” only for photos attached to pins β€’ Photo Library Add permission optional β€” only when saving an Instagram-bound landmark sticker GhostTrail does not detect ghosts. It logs environmental sensor readings as data, not as paranormal claims.
