App Concept

DiagFlow Pro

DiagFlow Pro is a mobile app that provides expert-guided, vehicle-specific diagnostic workflows for intermittent fault codes. Enter the fault codes and vehicle details, and the app presents a prioritized checklist of components to test, with instructions and likely fix rates, helping DIYers avoid costly trial-and-error part replacement.

Key Features

Fault code symptom matcher with frequency and conditions data from community reports
Step-by-step diagnostic tree with component test procedures and pass/fail criteria
Part compatibility database and direct links to verified suppliers
Cost estimator per diagnostic path including labor time and part prices

Target Users: DIY car owners and independent mechanics working on European diesel vehicles (e.g., VW, Audi, Skoda, Seat).

Revenue Model: Freemium: free fault code lookup; $9.99/month or $79.99/year for full diagnostic workflows and community data. One-time per-vehicle premium unlock at $49.99.
