Steer: OBD2 Car Scanner
AI Mechanic & OBD Diagnostics
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
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 — then explains it the way an honest mechanic would: in plain language, with no jargon and nothing to upsell you.
WHAT YOU GET:
■ 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.
■ 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.
■ 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 — Catalyst System Efficiency Below Threshold".
■ 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.
■ DASHBOARD LIGHT LIBRARY
Every warning light on your dashboard — check engine, ABS, airbag, TPMS, oil, battery — what it actually means, and how urgent it really is.
■ MAINTENANCE THAT KNOWS YOUR CAR
Service intervals based on your VIN and your real mileage, not a generic checklist. Oil changes, filters, brakes, belts.
■ SAFETY RECALLS
We check your VIN against the manufacturer recall database and tell you if your car is affected.
■ EVERY OBD2 CAR SINCE 1996
80 makes and thousands of models, 1996 to 2026.

• Redesigned welcome screen.
• Plugged in a non-Steer adapter? The app now tells you right away — and you can try the demo scan or get a Steer sensor.
• Your profile picks up your name from Apple or Google automatically.
• Stronger account control: deleting your account also revokes Steer's access to your Apple ID, and signing in to a deleted account is now clearly explained, with support one tap away.
