Your check engine light is on. Now what? Auto AI Diagnostics turns your iPhone into an AI-powered car diagnostic tool. Plug a Bluetooth OBD2 adapter into the port under your dash, tap scan, and AXEL — your AI shop foreman — reads the fault codes straight from your car's computer and explains what's going on in plain English or Spanish: what's happening, how serious it is, whether it's a DIY fix or a shop job, and what to do next. FEATURES: • Real fault codes pulled straight from your car's computer — engine and control modules • Automatic VIN read directly from your vehicle's ECU • AI-powered diagnosis with evidence and an action plan — not just a code definition • Fault code descriptions verified against the web for accuracy • View Conditions: see the mileage, battery voltage, and speed recorded when each fault set • Live engine data — RPM, coolant temp, battery voltage, throttle, and more • Odometer tracking with every scan • Scan history so you can track issues over time • DIY repair guidance and YouTube repair video suggestions for your exact vehicle • Ask AXEL follow-up questions about your specific car • Works with older, pre-2008 (K-line) vehicles too • The entire app in English or Spanish — including AXEL's AI diagnosis. Switch anytime. WHAT YOU NEED: A Bluetooth OBD2 adapter (ELM327-compatible, sold separately). It plugs into the OBD port under the dashboard on the driver's side — and on iPhone there's no pairing needed, the app finds it automatically. Works with most gas-powered cars and light trucks sold since 1996 (OBD2), including many pre-2008 K-line vehicles. Auto AI Diagnostics helps you understand your car and make informed decisions — it's information and guidance, not a substitute for a professional inspection when safety is on the line.

Worried about a light on your dashboard? DashLight AI tells you what it means in seconds. Just snap a photo of the warning symbol — or pick one from your library — and our AI identifies it, explains the problem in plain language, and tells you the one thing you really want to know: is it safe to keep driving? WHAT YOU GET • Instant identification of dashboard warning lights • A clear severity rating — Low, Medium, High, or Critical • "Can I keep driving?" guidance for every light • Likely causes and the recommended next step • An estimated repair-cost range so there are no nasty surprises • Detects multiple lights in one photo BUILT FOR REAL DRIVERS No jargon, no guesswork. DashLight AI turns a confusing symbol into a simple, confident answer — so you know whether to keep driving, book a garage, or stop right now. KEEP A HISTORY Save your scans and revisit them anytime. Handy for tracking a recurring issue or showing a mechanic exactly what came up. PREMIUM Upgrade for unlimited scans, the full diagnosis on every light, repair-cost estimates, unlimited history, and the AI Mechanic for follow-up advice. IMPORTANT DashLight AI provides general guidance and can be wrong. It is not a substitute for inspection by a qualified mechanic. If a red warning light is on, stop safely and have your vehicle checked. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
