AI Vehicle Diagnostic Help

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Stop guessing. Start diagnosing. EngineIQ Diagnostic is an AI-powered automotive diagnostic app built to help drivers, DIYers, mobile mechanics, and technicians find problems — not just replace parts. Most code readers stop at the trouble code. EngineIQ helps you go further. Enter your vehicle symptoms, diagnostic trouble codes, freeze-frame data, scan notes, repair observations, and test results. EngineIQ Diagnostic analyzes the information and helps rank the most likely problems from most probable to least probable, giving you a smarter path forward before you waste money on random parts. Whether you are dealing with a check engine light, drivability issue, no-start condition, sensor fault, misfire, fuel problem, electrical concern, or confusing scan data, EngineIQ helps organize the diagnostic process so you know what to check next. EngineIQ Diagnostic helps you: • Rank likely causes based on the information you enter • Follow a step-by-step troubleshooting workflow • Avoid guessing from codes alone • Reduce random parts swapping • Organize symptoms, notes, reports, estimates, and invoices • Build a clearer diagnostic path before making repair decisions • Work smarter as a DIYer, driver, mobile mechanic, or technician EngineIQ is not just another scanner app. It is designed to help you think through the problem, understand possible causes, and follow a structured workflow toward the real issue. Codes do not always tell the whole story. A P-code may point you in a direction, but it does not automatically tell you which part failed. EngineIQ Diagnostic helps you combine codes, symptoms, data, and observations into a ranked diagnostic approach. No more guessing. No more throwing parts at the car. No more wondering what to test next. Start with a 7-day free trial, then continue with EngineIQ Diagnostic for $14.99/month.
