Summary. Sonic Compass is an iPhone app that claims to train users toward an innate 'sense' of magnetic North using principles from cognitive science and predictive processing. Its core Learning Mode has users predict North's direction after a cue and then hear spatial audio feedback, an 'active inference' loop meant to build new neural pathways; a Sense Mode gives continuous ambient audio orientation, and a Vibration Mode offers silent haptic pulses when facing North. It targets hikers, accessibility users, urban travelers, and self-described biohackers interested in acquiring a previously inaccessible sense, and is developed by Mikhail Samin.
