Shadetree: Car Repair Advisor

Your car knows what's wrong with it. Shadetree helps you listen. Plug an inexpensive Bluetooth OBD-II adapter into the port under your dash and Shadetree records what your car reports on every drive: engine readings, transmission temperatures, fuel trims, battery and charging health, fault codes, and more. THE CAR PAGE IS THE DATA Open your car and everything it has said is right there. Anything worth watching is drawn as a chart with its history across drives. Tap any reading for what it means in plain language and its typical range. ASK ABOUT THIS CAR One tap gathers everything your car has reported, recent drives, trends, codes, and the weather they happened in, and opens the AI you already use (Google, ChatGPT, or Claude) with a mechanic's-eye question already asked. No VIN, no location, ever. YOURS, PRIVATELY No account. No ads. No trackers. Your drives, locations, and history stay on your iPhone and in your own private iCloud. Anonymous coverage sharing (which readings a model of car can answer) helps unlock readings for cars like yours; it never includes your VIN or location, and you can turn it off. A plain-English privacy policy in Settings says exactly what leaves the phone and when. Works with common ELM327-compatible Bluetooth LE adapters. Deep support for Honda vehicles today, with standard OBD-II readings on most cars sold since 2008. Try the built-in sample car before buying anything. Shadetree adds to your warning lights, your manual, and a real mechanic. It does not replace them.
