DiagFlow
DiagFlow is a mobile app that connects to any OBD-II scanner, instantly translates trouble codes into plain English, and runs a guided diagnostic tree to pinpoint the root cause. No more forum hopping or parts cannon – just data-driven fixes for your car's issues.
Key Features
- Instant OBD code interpretation with severity and common causes
- Step-by-step diagnostic workflows based on symptoms and live data
- Live data graphing for sensors (e.g., A/C pressures, transmission solenoids)
- Community-verified fixes with upvote/downvote system
Target Users: DIY car owners and weekend mechanics who own an OBD-II scanner and want to diagnose problems without relying on expensive shop visits.
Revenue Model: Freemium subscription: free tier includes basic code reading and 1 diagnostic per month; Pro tier ($4.99/month) unlocks unlimited diagnostics, live data graphing, and advanced workflows.
