Refueling 2013 E-150 cargo vans is extremely slow because the pump repeatedly shuts off after less than a quarter gallon, wasting time at the gas station.

Mechanics are unsure of the root cause and provide conflicting, expensive repair advice without a guaranteed fix.

Implied Software Gaps

Mobile diagnostic tool that quickly identifies evap system component failures causing pump shut-off during refueling

App Concept

EvapSnap Diagnostic

EvapSnap Diagnostic is a mobile app that uses a sensor adapter plugged into the vehicle's OBD-II port to instantly diagnose evaporative emission system issues. It walks the user through a step-by-step test, pinpoints the failing component (charcoal canister, purge valve, etc.), and recommends repair costs with local mechanic estimates. No more guessing or unnecessary repairs.

Key Features

Plug-and-play OBD-II sensor adapter for real-time evap system health
Step-by-step guided diagnostic test with pass/fail indicators
Component-level fault identification (charcoal canister, purge valve, vent valve)
Automated repair cost estimator with local mechanic recommendations

Target Users: Small business owners and fleet managers of commercial vans (e.g., E-Series, Transit) who experience slow refueling and want a quick, reliable diagnosis without mechanic guesswork.

Revenue Model: $14.99 one-time app purchase, plus $29.99 for the sensor adapter hardware. Optional $9.99/month premium subscription for unlimited diagnostics, fleet management dashboard, and priority mechanic matching.
