The free OBD2 app that tells you what the warning light actually means
Plug a cheap Bluetooth OBD2 adapter into your car, scan it, and get a plain-language answer in under a minute. No mechanic markup, no guessing. Free to start.
What you get for free
A check engine light, answered in plain English
Read and clear fault codes
Pull every stored OBD2 code, P0420, P0300, P0171 and the rest, then clear it once the fault is fixed. You never pay just to read a code.
Green-to-red safe-to-drive verdict
Every code gets a colour rating: green, yellow, orange or red. You know whether to keep driving or pull over, not just a cryptic number.
NHTSA recall lookup
Check your vehicle by VIN against open manufacturer recalls, explained in plain language with what to do next. No paywall on safety information.
Live engine data
Watch key sensor readings as you drive: coolant temperature, RPM, fuel trims and more, explained in plain language.
Ask the AI mechanic
Type a symptom or a code and get a plain-language explanation of the likely causes and what to check first. Free to try.
Compatibility
Works with most Bluetooth OBD2 adapters
Skanyx is hardware-agnostic. Any standard ELM327 Bluetooth OBD2 adapter, the kind that costs under 20 euros, plugs into the port under your dashboard and pairs with the app. If your car is petrol from 2001 or diesel from 2004 onward in the EU, it has the port.
No proprietary dongle to buy. Use the adapter you already have.
Free vs Pro
What is free, and what is not
Free
Reading and clearing codes, the safe-to-drive verdict, live sensor data, recall lookup by VIN, plus a taste of the AI mechanic. Enough to understand most warning lights yourself.
Pro, 12.99 euros per month
Unlimited AI diagnostics that remember your car, the 0 to 100 Health Monitor score, Inspection Readiness so you know if it will pass emissions, freeze frame data on every stored code, fault prediction that flags issues before they strand you, and your full history. Cancel anytime.
We will always let you read a fault code for free. That is the whole point of Skanyx.
Why Skanyx
Other free apps stop at the raw numbers. Skanyx tells you what they mean.
Apps like Torque and Car Scanner are good at streaming raw data, and Skanyx reads the same standard OBD2 data they do. The difference is the layer on top: a plain-language read of what the code means for your car, a colour verdict on whether it is safe to drive, and a health score you can act on without a workshop manual. For manufacturer coding or deep module work, a brand-specific tool is still the right call. Skanyx is built for the owner who just wants to know what is wrong and what to do next.
Free OBD2 app questions
Is Skanyx really a free OBD2 app?+
Yes. Reading and clearing fault codes, the safe-to-drive verdict, live sensor data and recall lookup are free, and you get a limited go at the AI mechanic too. Pro costs 12.99 euros per month and adds the Health Monitor score, Inspection Readiness, freeze frame data, unlimited AI diagnostics, fault prediction and full history, but you never pay just to read a code.
Which OBD2 adapter do I need?+
Any standard ELM327 Bluetooth OBD2 adapter works, the kind sold for under 20 euros online. Skanyx is hardware-agnostic, so there is no proprietary dongle to buy. Plug it into the port under your dashboard and pair it in the app.
Will it work on my car?+
If your car is OBD2 compliant, yes. In the EU that means petrol cars from 2001 and diesel cars from 2004 onward, and almost every car sold since. Skanyx reads the standard powertrain and emissions data that every OBD2 car shares.
Is it on iPhone and Android?+
Yes. Skanyx is live on both the Apple App Store and Google Play, free to download on iPhone and Android.
Do I need any mechanical knowledge?+
No, and that is the point. Skanyx translates the code into plain language, tells you with a colour whether it is safe to drive, and the AI mechanic explains what to check first. It is built for owners who do not know cars.
