About this app

Meet Strion. The co-pilot your car has been missing.

Plug a Bluetooth OBD2 adapter into your vehicle, connect once, and Strion quietly goes to work in the background: logging your trips, watching your engine's vitals, and decoding those mysterious dashboard warning lights, all in plain English.

No fiddling. No "start trip" button to forget. Strion knows when you're driving and when you've parked.

WHAT STRION DOES

Automatic trip tracking
Trips start and stop on their own using live engine data. Review every drive with detailed stats: distance, duration, and driving events.

Know your driving
Strion flags hard braking and hard acceleration so you can see (and smooth out) your habits behind the wheel.

Engine Health Check
Get an instant, easy-to-read health report built from your car's real-time sensor data. Spot trouble before it becomes a tow truck.

Decode the dreaded check-engine light
Strion reads diagnostic trouble codes (DTCs) and explains what they actually mean using a built-in offline fault-code database. So you visit your garage next time with awareness.

Your own Intelligent car expert
Chat with Strion's built-in intelligent assistant. Ask what a fault code means, what your engine health says about your car, or what to do next. Tap "Intelligent Analysis" on any code or health report for a clear explanation in seconds.

History, insights & reports
Browse your full trip history, track analytics over time, estimate your carbon footprint, and export polished PDF reports to share or keep.

WHAT YOU'LL NEED
- A Bluetooth (BLE) OBD2 / ELM327 adapter
- A vehicle with a standard OBD2 port (most cars from 1996 onward)

Whether you're a curious commuter, a weekend gearhead, or just tired of guessing what that orange light means; Strion turns your car's hidden data into something you can finally use.

Plug in. Drive. Let Strion handle the rest.
Your car's AI co-pilot: Track trips, check engine health & decode fault-codes.
