App Concept
DiagFlow Pro
DiagFlow Pro is a diagnostic decision support app for DIY mechanics and small shops. It guides users through a structured troubleshooting tree based on symptoms, codes, and vehicle make/model. Unlike generic OBD scanners or forums, it narrows down tests dynamically, reducing guesswork and costly part swaps.
Key Features
- Code-specific troubleshooting trees with vehicle make/model/year filters
- Step-by-step guided tests with pass/fail logging
- Community-verified fix database with success rates
- Parts and test ordering integration within the app
Target Users: DIY mechanics and small automotive repair shops that need efficient diagnostic guidance for intermittent or complex fault codes.
Revenue Model: Freemium with $4.99 per diagnostic tree unlock or $29.99/month unlimited access subscription.
