About

Finder of Hidden Things The Goblin is a performance tool for mentalists, magicians, and experimental artists who work with hidden magnetic props. It allows you to sense when a magnetic object or an object containing a concealed magnet is moved near your phone. The app listens to changes in the phone’s built-in magnetic sensor and responds in real time with subtle haptics or vibration. This is not a proximity scanner, and it does not track people, objects, or locations. A magnet sitting still may produce little response. Movement creates change, and change is what the Goblin reacts to. Designed for live performance, the Goblin behaves more like a living creature than a simple meter. It learns the room’s background magnetism, filters environmental noise, and reacts only when something genuinely changes. This keeps behaviour stable in real-world venues such as theatres, bars, homes, and outdoor spaces. Features: • Magnetic movement sensing using the phone’s magnetometer • Adjustable Fog control to balance sensitivity and stability • Discreet haptic feedback or strong vibration modes • Stealth Mode for pocket and walk-around performance • Automatic noise filtering and room adaptation • Hands-free operation once configured Typical Uses: • Detecting movement of a concealed magnetic ring or coin • Performance cues for mentalism and magic routines • Creative exploration of magnetic motion The Goblin does not collect personal data and does not use the camera. All sensing happens locally on your phone.
