App Concept
BlowByPro
BlowByPro is a mobile app that guides DIY mechanics through engine blow-by diagnostics using video analysis and sound recognition. It interprets blow-by severity from engine RPM video and recommends step-by-step mitigation methods (e.g., catch can, high-mileage oil additives) or when a teardown is unavoidable.
Key Features
- Video-based blow-by severity analysis using RPM and smoke pattern recognition
- Personalized mitigation plan from a database of known engines and common fixes
- Step-by-step video guides for catch can installation, additive use, and compression test
- Community Q&A with verified mechanics for edge cases
Target Users: DIY boat owners and classic car enthusiasts who maintain older engines but lack professional mechanical training
Revenue Model: $9.99 per diagnostic report or $4.99/month subscription for unlimited diagnostics and guides
