01 / The constraintBEFORE

Affordable OBD tools produce screenshots and opaque readings with little provenance, poor comparison, and no trustworthy handoff between owners, buyers, technicians, and fleets.

02 / The responseSHIPPED

A mobile and API platform for standard OBD reads, guided evidence scans, signed device records, deterministic comparisons, offline verification, public NHTSA context, and conservative diagnostic workflows.

— / The build

A local-first vehicle evidence platform that pairs with compatible customer-supplied adapters, preserves exactly what the car reported, and turns diagnostic sessions into privacy-reduced records another device can verify offline.
