Your car has been trying to tell you something. Steer translates it. Plug the Steer sensor into the port under your steering wheel and the app reads what your car already knows โ€” then explains it the way an honest mechanic would: in plain language, with no jargon and nothing to upsell you. WHAT YOU GET: โ–  AI MECHANIC Ask anything about your car and get a straight answer. Send a photo of a warning light, a leak on the driveway or a part you don't recognize, or just describe the noise it makes. It knows your exact car and your latest scan. โ–  ONE NUMBER, 0 TO 100 Your Steer Score answers "how is my car right now?". No trouble codes to look up, no tables to read. Watch it move over time. โ–  PROBLEMS IN PLAIN LANGUAGE Every issue comes with what it means, whether it is safe to keep driving, and what the repair usually costs. Not "P0420 โ€” Catalyst System Efficiency Below Threshold". โ–  DEEP SCAN 21 systems and 126 live parameters, across every module your car will talk to. Start it, lock your phone, and get a notification when it is done. โ–  DASHBOARD LIGHT LIBRARY Every warning light on your dashboard โ€” check engine, ABS, airbag, TPMS, oil, battery โ€” what it actually means, and how urgent it really is. โ–  MAINTENANCE THAT KNOWS YOUR CAR Service intervals based on your VIN and your real mileage, not a generic checklist. Oil changes, filters, brakes, belts. โ–  SAFETY RECALLS We check your VIN against the manufacturer recall database and tell you if your car is affected. โ–  EVERY OBD2 CAR SINCE 1996 80 makes and thousands of models, 1996 to 2026. TRY IT BEFORE YOU BUY Open the app and tap "Try a real scan". You get the whole experience on a demo car โ€” scan, results, AI Mechanic โ€” with no sensor, no account and no card. WHAT YOU NEED Steer works with the Steer OBD2 sensor, available at steer.so. It is not compatible with third-party adapters. MEMBERSHIP Free forever: live codes, battery alerts and basic diagnosis.
