Every room hums with signals you can't see. Quantum Ghost reads them and shows you what crossed over, anchored in your real space, born from your real environment. The veil is thinner than you think. Every room you walk through is full of signals: quiet, constant, invisible. Quantum Ghost reads them, and shows you what they have become. This is not a game of random spawns. Every entity is generated from the real Bluetooth environment around you: its class, its form, its behavior, and its name all derive from the actual signals in your actual room. A stable, long-settled signal becomes something rooted and patient, and it was here before you and it intends to stay. An anonymous, erratic one becomes something you will wish you had not found. Walk into a crowded café and something enormous stirs in the noise. Stand in true silence, and you may meet what remains when every signal is gone. HUNT WITH YOUR PHONE • Sweep the room and watch presences resolve out of the noise • Walk to triangulate: every entity holds a real position in your space • Hold it in frame as it manifests, then document what you see • They drift, they retreat, they flee. Look away and you can lose one. PROCEDURAL, NEVER PRE-RENDERED Every apparition is generated in real time by Metal shaders. No artwork, no sprites, no repeats. The same device always produces the same entity. The presence in your kitchen is yours, and it is consistent every time you return to it. TWELVE QUANTUM ZONES The world is divided into twelve zones, each producing species found nowhere else. The Boreal Sentinel stands watch where the forest goes quiet under snow. The Abyssal comes up from pressure nothing on the surface survives. Where you travel changes what crosses over. IT HAS A VOICE Every entity is synthesized in 3D space: a rooted hum, a distant wail, a heartbeat that outlived its owner. Wear headphones and you will hear it behind you before you turn around. YOUR COLLECTION • A Codex of 26 species, revealed as you document them • Quantum Captures, each a unique record carrying the signal that made it • A Haunting Map of the ground you have covered • A Geo Passport tracking all twelve zones • Streaks, achievements, and shareable Haunting Reports PRIVACY BY ARCHITECTURE There is no server. No account. No ads. Nothing you scan ever leaves your device. The app never connects to nearby devices, never reads their contents, and never touches MAC addresses. It listens to the public broadcasts every device already makes, and turns them into ghosts. Location is coarsened to roughly 100 meters before it is used at all, and it is entirely optional. Anonymous usage and crash diagnostics can be switched off in Settings. REQUIRES An iPhone running iOS 18 or later, with Bluetooth and camera access. LiDAR-equipped iPhones (Pro models, iPhone 12 Pro and later) add full room-mesh occlusion, so entities hide behind real objects; all other iPhones play with standard AR. The more signals around you, the more crosses over. QUANTUM GHOST PRO A one-time unlock, no subscription. All 26 entities including every Rare, Ultra Rare, and Legendary class, full Codex lore, EVP transcripts, unlimited Haunting Map pins, and unlimited report exports.
