Liminal Finder

Liminal Finder is an observational entertainment app that uses sensors built into your device to search for places where the boundary feels thin.

It combines subtle changes detected by motion, magnetometer, barometer, location, and ambient-sound measurements to visualize the “thickness” of the boundary around your current location.

■ Observations based on sensor readings Every displayed value comes from measurements actually detected by the device. The app does not inflate readings with random numbers. Some days, nothing unusual will happen.

■ Explore on foot Walk, change direction, and choose quieter places. Continued movement helps the observation settle.

■ Deep Search When the observation conditions align, Deep Search becomes available. Cover the rear camera lens for 10 seconds to measure dark-frame noise. Camera images and audio are never saved or transmitted.

Liminal Finder is intended for entertainment. It presents effects based on device sensor values and does not detect or prove supernatural or parallel-world phenomena.
