Map the Unmappable Underground.
Turn echoes and footsteps into precise 3D cave maps — no GPS, no line-of-sight, no tedious manual sketches.
You're crawling through a tight passage 200 meters below the surface, sketching on wet paper with a compass that keeps drifting. By the time you surface, half your notes are smudged and the geometry doesn't close. SonicQuilt listens to the ambient sound bouncing off cave walls and tracks your movement to stitch together a living 3D "quilt" of every chamber, squeeze, and passage — automatically, as you explore. Surface with a complete, share-ready survey instead of a pile of cryptic field notes.
Hands-Free Mapping While You Explore
SonicQuilt builds the map from sound and motion as you move, so your hands stay free for climbing, rigging, and safety.
Accurate Geometry Without GPS
Acoustic profiling captures passage width, ceiling height, and chamber volume where satellite signals can't reach.
Real-Time 3D Preview Underground
See the quilt grow on your device as you survey, catching missed passages before you leave the cave.
Instant Export to Standard Formats
Export to Therion, Survex, or OBJ with one tap — no hours of digitizing paper sketches back at camp.
