STEER Sensor
STEER plugs into your car and tells you, in plain English, exactly how it's doing. No jargon. No guessing. Just the simple truth, every time you drive.

Three steps. That's the whole thing.
No tools. No appointment. No idea what "OBD2" means required.
Plug it in
Find the port under your dashboard — the app shows you exactly where. STEER clicks in and stays there. It takes about a minute.
Open the app
Download STEER for iPhone and sign in with your email. It finds your car on its own — you don't enter anything.
Know your car
You get a single score from 0–100 and a plain-English summary of how your car is doing. That's it. You're done.
iPhone required (iOS 18 or later). One STEER works in any car — move it between vehicles anytime.
Your car, finally in plain English.
A single score, 0–100
One number tells you how your car is doing right now. Up is good. Down means take a look.
Plain-English alerts
Instead of "P0171", you get "your engine is running slightly lean — here's what that means and whether it's urgent".
A heads-up before you drive
If your battery is getting weak, you'll know in the morning — not on the side of the road.
Recall checks
STEER checks your car against official US recall data automatically, so you're never the last to know.
Ask the mechanic, anytime
Got a worry? Ask in your own words and get a calm, honest answer. (For safety concerns, always see a certified mechanic.)
Every car in one place
One STEER, or one for each car. The app keeps the full history for all of them — under one subscription.
Included free for 14 days with every order.
Your STEER comes with the app, and the app is useful on its own — you'll always see your car's score, how many issues it found, and whether anything is a safety concern. That part is free, forever.
STEER Pro is the full picture: the why behind every alert, what it'll likely cost to fix, monthly health reports, instant notifications when something changes, and the mechanic chat. It's the difference between "something's off" and "here's exactly what's off, and what to do".
Every order includes 14 days of Pro, free. We turn it on at checkout so you can use the thing you bought from day one. If it's not for you, turn it off in two taps before day 14 — you won't be charged. After that it's $99 a year — about $8 a month, less than a single diagnostic visit at a shop, and one subscription covers every car in your household.

Does it work with your car?
Built for any car sold from 1996 onward — over 99% of what's on the road. Two clicks to check yours.
Not sure? Order it — if it doesn't work with your car, send it back within 30 days for a full refund. Technically: STEER connects through the standard OBD2 port every car has had since 1996. iPhone with iOS 18+ required.
Built by people, not a faceless brand.
Most people aren't car people. They just want to get to work, get the kids to school, and not get stranded — without feeling talked down to at the repair shop.
We built STEER for them. Not for mechanics, not for gearheads. For the person who sees a dashboard light and just wants a straight answer: is my car okay, yes or no.
It's a small device, a simple app, and an honest promise — we watch your car so you don't have to worry about it. That's the whole company.
— Sebastian Pardo, Founder
If it's not right, we make it right.

Everything you might be wondering.
Will it work with my car?
Almost certainly yes. STEER works with virtually every car made from 1996 onward, across every major brand. It needs an iPhone running iOS 18 or later. If it doesn't work with your car, return it within 30 days for a full refund — no questions.
Do I need to be good with cars or tech?
No — that's the whole point. If you can plug in a phone charger and use an app, you can use STEER. It explains everything in plain English. No codes, no jargon, no manual.
Is the subscription required?
No. The STEER app works for free — you'll always see your car's score, how many issues were found, and whether anything is a safety concern. STEER Pro adds the detailed explanations, repair-cost estimates, alerts, and the mechanic chat. Every order includes 14 days of Pro free, so you can decide for yourself.
What happens after the 14-day free trial?
If you keep Pro, it's $99 a year — about $8 a month, and one subscription covers every car in your household. If Pro isn't for you, turn it off in the app before day 14 and you won't be charged a cent. We email you on day 11 as a reminder. The free app keeps working either way.
How do I cancel Pro?
Two taps inside the app, anytime. No phone calls, no emails to send, no "are you sure" maze. If you cancel during the trial, you pay nothing.
Is it safe for my car?
Yes. STEER only reads information your car already produces — it doesn't change anything or send commands to your car. It's the same kind of connection a mechanic's tools use, and it's FCC and CE certified.
When will it arrive?
Orders ship in 3–5 business days with free shipping. You'll get tracking by email as soon as it's on its way. We currently ship to the United States and the European Union.
What if I have two or three cars?
One STEER moves between cars in seconds, or get a 2-pack or 3-pack so every car has its own. Either way, one STEER Pro subscription covers your whole household — you never pay per car.
Stop wondering about your car.
Plug in STEER, open the app, and get the simple truth — every time you drive. 14 days of STEER Pro included, free.
