About this app

Steer turns your car's data into plain English. Plug the Steer Sensor into your car's OBD2 port, open the app, and know what's wrong, how urgent it is, and what the repair should cost — before it becomes an expensive surprise.

IMPORTANT: Steer works exclusively with the Steer Sensor (available at steer.so). It is not compatible with generic ELM327 or other third-party OBD2 adapters.

WHY STEER

Most car owners don't speak mechanic. Steer is built for the rest of us: no raw codes, no jargon — just clear answers about your car's health and what to do next.

ONE DEEP SCAN, THE FULL PICTURE
• Scans 21 vehicle systems and 126 parameters in minutes
• Reads the systems behind your dashboard warning lights, including the check engine light
• Find out at home — not on the side of the road

STEER SCORE — YOUR CAR'S HEALTH AT A GLANCE
• One 0–100 score that tracks your car's overall health
• Watch it improve as you fix issues, and catch problems while they're still cheap

ISSUES & SAFETY — WHAT'S WRONG, AND WHAT TO DO
• Every fault code translated into plain English
• Severity and urgency for each issue: keep driving, schedule it, or stop
• Know what each repair should cost before you walk into the shop — stop overpaying

PREDICTIVE MAINTENANCE — A FORECAST FOR YOUR CAR
• A maintenance plan built from your car's real mileage and condition
• A timeline of what's coming: oil, brakes, filters, rotations
• Reminders before things are due, so small services never become big repairs

AI MECHANIC — THE AI THAT KNOWS YOUR CAR
• Not a generic chatbot: it's connected to your car and your scan history
• Ask anything — "My check engine light just came on. Can I keep driving?" — and get an answer based on your car's real data
• Add photos or ask by voice, and get repair cost estimates for your area

BATTERY HEALTH
• Tracks your battery's cranking and resting voltage over time
• Know it's dying before the morning it leaves you stranded
